About this episode

Russ Evans and Shannon Nordstrom field a string of real-world repair questions focused on saving money and avoiding expensive misdiagnoses. A 2015 F-150 radio/audio issue turns out to be hacked wiring and missing OEM harness/amp modules, with advice to source the correct pigtails and modules from car-dash-part.com or use a stereo shop to keep factory integration. Other calls cover Honda timing chains vs belts, flex-fuel “rich” codes from improper fuel blending, TPMS sensor failures and why they’re usually tire-mounted, and an overheating Buick where temperature-drop and head-gasket checks come first. Practical tips and “fix it once” guidance throughout.

"Spring into deals for seasonal savings. Shops select one pint annuals for just two dollars, plus get a free additional cobalt 40 volt 2 amp hour battery. When you buy, select cobalt 40 volt trimmer and blower combo kit. Our best lineup is here at Lowe's."

Lowe’s is a store where you can buy tools and supplies. They were talking about a sale on items like batteries and tool kits.

Brand

cobalt 40 volt trimmer and blower combo kit

"plus get a free additional cobalt 40 volt 2 amp hour battery. When you buy, select cobalt 40 volt trimmer and blower combo kit. Our best lineup is here at Lowe's."

Cobalt makes cordless tools. The “40 volt” part means the battery is part of a specific tool system, so you may be able to use the same battery in different tools.

This sponsor is a place to buy used car parts. Buying used parts can cost less, but you should double-check that the part will fit your exact vehicle.

Car

Ford F150

"But I bought a 2015 F-150 here in Charlotte, and everything seemed to be all right other than the radio didn't work. I said there was no sound."

This is a Ford F-150 pickup from 2015. The speaker’s truck had a radio/audio problem—no sound—and they had to figure out what was wrong with the wiring and parts behind the seats.

Term

wiring issue

"I figured it'd be something simple as a small wiring issue or something a fuse or so I go at home and I get to digging into it a little more and a little more. Yeah, it's a it's a wiring issue."

A wiring issue means the wires that carry power or audio signals aren’t connected correctly. In this case, someone cut the wires behind the seat, so the radio can’t work until the connections are restored.

Term

fuse

"I figured it'd be something simple as a small wiring issue or something a fuse or so I go at home and I get to digging into it a little more and a little more."

A fuse is like a safety switch for the electrical system. If too much current flows, it “blows” to prevent damage, and that can stop things like a radio from working.

Term

pigtail

"My problem is now I'm trying to find their original equipment, but I also need a pigtail that is OEM connection back to an OEM receiver and all the other hardware."

A pigtail is a short wiring harness section with the correct connector on one end and bare leads on the other. It’s commonly used to splice into a vehicle’s factory wiring without cutting the main harness, making repairs and upgrades cleaner.

Concept

aftermarket radio and receiver

"And their suggestion is to go to an aftermarket place and see if they could either build me one or just change the whole system out to an aftermarket radio and receiver and sub and module and whatever else I need."

An aftermarket radio is a replacement stereo that isn’t the original factory one. If the factory wiring parts are hard to find, you may need adapters or extra pieces so the new stereo fits and works correctly.

Term

VIN number

"They have all kinds of receivers and parts on their list when I put the VIN number in, but I can't, I can't seem to find a contact number."

The VIN is like your truck’s unique ID number. Parts sellers use it to figure out exactly what your vehicle needs so you don’t buy the wrong connector or module.

Concept

data bus

"…the radio is, is, is on the, is on the data bus and it's communicating with other stuff. So you need all that OEM stuff to work together…"

Modern cars don’t run each gadget separately. Instead, many computers in the car talk to each other through a shared network. If that network setup isn’t right, the radio and other electronics can malfunction.

Term

OEM

"So you need all that OEM stuff to work together, or you have to get an aftermarket kit that allows you to convert it properly."

OEM just means the exact parts made for your car by the original manufacturer. With newer cars, using the right parts (or a kit meant for your exact setup) helps everything communicate correctly.

Term

aftermarket kit

"…or you have to get an aftermarket kit that allows you to convert it properly. So now, having said that…"

An aftermarket kit is a set of parts made by a company other than the car maker to make upgrades work. It’s especially important in newer cars because the electronics may need special adapters to communicate properly.

Concept

truck that went through an auction

"…usually what it ends up being is a truck that went through an auction. This is my, my best case scenario. It's a truck that went through an auction that had been used as a job truck…"

Auction trucks can have a sketchy past. If they were used for work, someone may have removed parts (like seats) and later tried to put things back, but not everything gets restored correctly.

Term

retrofit

"…sometimes they'll put things back there and then somebody will retrofit it and put it back to an interior again."

A retrofit is when you add parts to a car after it’s already been built. Sometimes people make it look right, but the underlying wiring or electronics may still be incomplete.

Term

amplifier

"…if you look up somebody that has the proper amplifier, there might be a module associated with that system, but I would more go for the amplifier because I believe that's what sits back in that back corner…"

An amplifier is the part that makes the audio loud and clear by powering the speakers. If the wrong amplifier (or missing audio hardware) is installed, the sound system can act up even if the radio itself looks fine.

Term

harness

"...to go out and get you the harness or cut it off as you need. Sometimes the cutting off part is not the best option..."

A harness is basically the car’s wiring bundle—wires that connect everything together. If someone cuts it or removes parts, you may need the right wiring pieces to make the system work correctly again.

Term

digital

"...some of these run a little bit of digital, some run coax. It's not as easy to splice that stuff..."

“Digital” here means the audio signal is sent in a more computer-like way. If the wiring is cut or spliced incorrectly, it can be harder to get the signal working cleanly again.

Term

coax

"...some of these run a little bit of digital, some run coax. It's not as easy to splice that stuff. Russ, go ahead. There's parts you can buy to splice coax."

Coax is a specific kind of cable used for certain signals. It’s not always as easy to splice as regular wires, so a bad splice can cause audio problems.

Term

aftermarket sub

"...somebody properly cut the wires. They installed an aftermarket sub back there, maybe a different amp..."

An aftermarket sub is a non-factory speaker for bass, usually added with extra wiring and an amp. If it was removed later, the wiring behind it might be damaged or cut.

Term

modules

"...while I'm buying that, I want to buy all the modules that were plugged into it..."

Modules are electronic control units that plug into the vehicle’s wiring harness to manage functions (in this case, likely audio-related components). When buying harness sections, you may also need the matching modules that were originally connected, otherwise the system may not function as expected.

Concept

factory stereo vs aftermarket audio repair choices

"...your two choices like Shannon said, car dash part. ...the second option is get it into a car stereo repair shop... keep the head unit... but get yourself an amp and speakers... put a sub behind the seat... third option is just take it all out..."

They’re basically saying you have three ways to fix a messed-up factory audio system: keep the factory stereo by repairing the wiring, keep the factory head unit but upgrade the speakers/amp/sub, or rip it all out and install a new in-dash system. Which is best depends on what you want to keep and how bad the wiring damage is.

Term

head unit

"...they might be able to do what the previous owner had, keep the head unit, the dash with navigation, whatever you had..."

The head unit is the main screen/radio in the dash. If you keep it, you can often preserve features like navigation while upgrading the speakers and sub.

Term

sub behind the seat

"...get yourself an amp and speakers put in back there, they'll put a sub behind the seat..."

A “sub behind the seat” is a compact subwoofer location used in many vehicles to save space while still adding bass. If the wiring for that sub was cut during removal of an aftermarket setup, restoring the correct connections is often necessary to get bass back without rattles or distortion.

Term

car stereo shop

"so I think if you get into a car stereo shop, they would be able to look at it and probably get you hooked up with an amp in there."

A car stereo shop is a place that installs and repairs car audio. They can help figure out what’s wrong with the sound system and what parts you actually need.

Term

key fob

"...I went yesterday to get a key because I only had one fob and so it's a push button. So I was going to get another fob programmed at a locksmith..."

A key fob is the remote transmitter used to lock/unlock and often start a vehicle with push-button ignition. Programming a key fob typically requires the vehicle to communicate with its receiver/immobilizer system, so missing components can block the process.

Term

push button

"...it's a push button. So I was going to get another fob programmed at a locksmith..."

Push-button start means you start the car by pressing a button, usually with the fob nearby. If the car’s keyless system isn’t working right, programming a new fob can fail.

Term

programmed

"...he goes out plugs into it, but it won't, it won't program the key... till you fix that problem, I can't, I can't get a key programmed because it won't communicate with the truck."

Programming means setting up the new remote so the car recognizes it. If the car can’t communicate with the key system, the remote won’t get accepted.

Concept

communication port

"...if the communications down, if the information's already in there, think about it like a home computer that used to have a CD drive... if somebody opens that door and rips the CD drive out, you can't put anything new in it."

Think of it like a computer missing a plug-in port. Some things might still work, but you can’t add new devices or make new connections until the missing link is restored.

Term

clone key

"...you could just go down to ACE hardware, have a clone key made of your key... it thinks it's got two of the same key in it and not two separate keys."

A clone key is basically a copy of your existing key that the car already recognizes. It can be an easier workaround when programming a brand-new key fob isn’t working.

Company

ACE hardware

"...you could just go down to ACE hardware, have a clone key made of your key. And then that would work on the truck..."

ACE Hardware is mentioned as a place that can cut and clone keys. While key-cutting services vary by location and key type, the episode’s point is that a physical key duplicate may be cheaper and faster than full electronic reprogramming.

Car

Honda Accord

"Jim, what can we do for you? Well, I was listening last week when you were talking about the timing belt or the belt partner on a Honda Accord, I think it was. Right. We were talking about the external belt that runs the alternator and the, you know, power steering on cars and air conditioner and all that."

They’re using the Honda Accord as an example to explain what parts you might need to replace. Some cars use a timing belt or timing chain, and there’s also a separate belt that runs things like the alternator and power steering.

Term

external belt

"Right. We were talking about the external belt that runs the alternator and the, you know, power steering on cars and air conditioner and all that."

This is the belt on the outside of the engine that powers things like the alternator and air conditioning. If it starts squealing or slipping, it can affect multiple systems, so replacing it promptly helps prevent bigger problems.

Company

Daco complete belt kit

"And we were talking about the Daco complete belt kit, which allows you to replace the whole system at once instead of just one piece... At that point, what we suggest is the belt kit that Daco has. And we use those in our shop... it needs a belt and it needs a tensioner and the idler as a kit."

A complete belt kit means you replace the belt plus the other parts that help it stay tight and run smoothly. Doing it all together can be cheaper and prevents the problem from coming back if the tensioner or idler is worn.

Concept

replace the whole system at once (belt kit approach)

"And we were talking about the Daco complete belt kit, which allows you to replace the whole system at once instead of just one piece... it needs a belt and it needs a tensioner and the idler as a kit. And it's cheaper to get it all together."

Rather than replacing only the belt, the idea is to replace the belt and the other parts that make it run correctly. That way, you’re less likely to have the same squeak or problem come back soon.

Term

timing chain

"That was the timing. That was the other one. That was the timing chain. What's your thoughts on that? Well, I'm just inquiring about a 2015 Honda Civic... Well, there's no maintenance on either one. If everything's working well for, so like on the timing chain side, if there's no noise when you start it, the chain is meant to last the life of the engine."

A timing chain performs the same job as a timing belt—keeping crankshaft and camshaft timing synchronized—but it’s typically designed to last much longer. The speaker notes that if it’s quiet and maintained, it can last for the life of the engine, though noise like rattling can be an early warning sign.

Car

Honda Civic

"Well, I'm just inquiring about a 2015 Honda Civic. I assume that has to have the same changes made or maintenance on that. Well, there's no maintenance on either one. If everything's working well for, so like on the timing chain side, if there's no noise when you start it, the chain is meant to last the life of the engine... But as far as the belts go, when it does come time to replace a belt... you're 11 years old already in the Civic, so it's getting real close to belt time."

They’re talking about a 2015 Honda Civic and what usually needs replacing as it gets older. The timing chain is often expected to last a long time, but the belts that run accessories can wear out and may need a full kit when they start making noise.

Term

oil changes

"And with proper maintenance to the vehicle, you know, three months, 3000 mile oil changes on this specific car, longer drives, they'll typically last a very long time."

Oil changes are used here as a proxy for proper engine maintenance that helps timing chains last longer. Clean, correctly maintained oil reduces wear and helps the engine run quietly, which the speaker ties to timing chain longevity.

Car

Honda Crvs

"...g. They've got 300,000 miles on these Civics and CRVs and things. So they're fine. But as far as the be..."

The Honda CR-V is a small SUV made for everyday driving and family use. The podcast is pointing out that CR-Vs can last a long time, even with very high mileage. That’s usually a sign it’s a dependable vehicle to own.

Term

tensioner

"Okay, well, you didn't tell me it's squeak. We had squeaks sometimes in the morning. Okay, well, it needs a belt and it needs a tensioner and the idler as a kit."

A belt tensioner keeps the accessory belt tight and properly aligned as it stretches and wears. If the tensioner is weak or failing, a new belt can still squeak or slip, which is why shops often replace the tensioner as part of a belt kit.

Term

idler

"Okay, well, you didn't tell me it's squeak. We had squeaks sometimes in the morning. Okay, well, it needs a belt and it needs a tensioner and the idler as a kit."

An idler pulley helps guide the accessory belt and reduces friction and misalignment. Like the tensioner, an idler can wear out and cause noise (squeaking) or belt tracking issues, so replacing it with the belt kit can fix the root cause.

Term

dry belts

"If your car is running good and it's quiet, enjoy that smooth run in Honda and keep an eye on your dry belts just like any other car"

“Dry belts” refers to accessory drive belts (like serpentine belts) that can wear, crack, or become noisy when they dry out. Belt condition matters because a failing belt can affect multiple systems (alternator, water pump on some engines, power steering on others).

Car

2009 Chevy Impala

"Here's my issue. I got a 2009 Chevy Impala with 125,000 miles. I got a P0 172, which is a rich code. I've owned this car for about three years. It is a flex fuel vehicle."

A 2009 Chevy Impala is a car model from Chevrolet. Yours is described as a flex-fuel version, which means it can run on gasoline or ethanol blends, and that’s why the computer is tracking “alcohol content.”

Term

P0 172

"Here's my issue. I got a 2009 Chevy Impala with 125,000 miles. I got a P0 172, which is a rich code. I've owned this car for about three years."

P0172 is a check-engine code that usually means the engine is running “too rich,” or using more fuel than it should. On a flex-fuel car, ethanol blend changes can make the computer’s fuel calculations more sensitive.

Term

E85

"It is a flex fuel vehicle. I've never run E85 in it. Get the same top tier gas from the same station all the time."

E85 is a fuel that’s mostly ethanol. Since it’s not the same as regular gas, the car has to change how it runs to make it work correctly.

Concept

flex fuel vehicle

"It is a flex fuel vehicle. I've never run E85 in it. Get the same top tier gas from the same station all the time. In February of 25, I had a high alcohol content at 78%."

A flex-fuel car can run on different mixes of gasoline and ethanol. The car’s computer has to figure out what blend you’re using so it can adjust how much fuel to inject.

Term

alcohol content

"In February of 25, I had a high alcohol content at 78%. The fix at that time was to reset the computer and it went back to normal. I've got same problem. This month, alcohol content shows 54%."

“Alcohol content” is the car’s estimate of how much ethanol is in the fuel. Even if you don’t have an alcohol sensor, the computer can still guess based on how the engine is running.

Term

reset the computer

"In February of 25, I had a high alcohol content at 78%. The fix at that time was to reset the computer and it went back to normal. I've got same problem."

Resetting the computer means clearing the car’s stored fault info so it can start fresh. It can make the problem seem gone for a bit, but it doesn’t fix the cause if the issue keeps happening.

Concept

flex fuel systems don't use a sensor

"So the systems don't use a sensor. When they use the sensor, the only problem they would ever encounter was that sometimes the sensor would fail."

The host is saying the car may not directly measure ethanol with a special sensor. Instead, it figures out the fuel blend indirectly, so the readings can still shift even without a sensor being present.

Term

run that tank of fuel all the way down to less than a quarter, like an eighth of a tank

"They have the parts on the car already to do it. Most of them are working pretty good, but the problem is when you run in flex fuel, you need to run that tank of fuel all the way down to less than a quarter, like an eighth of a tank,"

The advice to run the tank low is about getting a representative sample of the current fuel blend into the system. In flex-fuel diagnostics, if the tank still contains older fuel, the car’s inferred ethanol percentage can lag and keep reporting inconsistent “alcohol content” until the new blend dominates.

Car

BMW E30

"...change it to something else. If you're going E85, E30, anything but E20 and below, you need to do that..."

The BMW 3 Series is a luxury car that comes in different body styles, most commonly a sedan. The podcast is talking about using certain types of fuel with higher ethanol content, and it’s warning that not all ethanol blends are appropriate. Using the wrong blend can cause problems if the car isn’t set up for it.

Term

fuel gauge / tank fill percentage change

"...your fuel gauge is going at least a certain percentage of it, it's about 60%, I think 60 to 80%. If it sees that much of a change when you restart the car, it knows you refueled it."

When you refuel, the car notices the tank level jump. Then it watches how the oxygen sensor readings change to figure out what kind of fuel it’s now burning. If the change is messy (like topping off with a different blend), the car may not interpret it correctly.

Term

oxygen sensor

"...it looks at the oxygen sensor now compared to the oxygen sensor before that change occurred... it sees, whoa, we're really lean, we must have increased the alcohol content. Let's dump more fuel... should I change the oxygen sensors?"

The oxygen sensor tells the computer whether the engine is burning fuel “too rich” or “too lean.” If the readings change a lot after refueling, the computer tries to correct the fuel mixture. If the sensor is worn out, it can give misleading information.

Term

mass airflow sensor (MAF)

"...dirty air system, air intake system in the car. Mass airflow sensor dirty? ...the mass airflow sensor is the biggest... we did to fix these other two cars was a new mass airflow sensor..."

The mass airflow sensor measures how much air is going into the engine. The computer uses that number to decide how much fuel to inject. If the sensor is dirty or wrong, the car can add or subtract fuel in the wrong way.

Term

CRC emission system cleaning kit

"...we did to fix these other two cars was a new mass airflow sensor and a CRC emission system cleaning kit, which cleans the..."

This is a cleaning product made by CRC for emissions-related parts. The idea is to remove buildup that can affect how the engine runs and how the sensors read. In the story, it helped after they also fixed the airflow measurement.

Term

throttle body cleaner

"...we used to clean the mass airflow sensor, we use the throttle body cleaner to clean the throttle body. And we use the injection system cleaner in the tank to clean the engine."

The throttle body controls how much air gets into the engine. Over time, carbon buildup can make it less responsive or affect airflow. Using throttle body cleaner helps remove that buildup.

Term

injection system cleaner (in the tank)

"...we use the injection system cleaner in the tank to clean the engine. And then we reset everything and we're good."

This is a fuel additive you put in the gas tank to help clean the fuel system. It can reduce gunk that affects how the injectors spray fuel. It’s usually used as maintenance or as part of a troubleshooting plan.

Term

fuel trims

"...I can instantly see what's going on with the fuel trims, because the first thing I did, I looked and I said, here we go, we got high alcohol content... So I reset that. And then I took it for a drive."

Fuel trims are the car’s “corrections” to make the mixture run right. If the trims move a lot, it can mean the car is compensating for something—like dirty sensors or different fuel. Monitoring trims helps confirm what’s really going on.

Term

zirconium

"...they've got zirconium in them, which wears as the sensor runs, it's made to dissipate. That's how part of the way the sensor works."

Zirconium is a material used inside many oxygen sensors. It helps the sensor “sense” oxygen in the exhaust and send a signal to the computer. Over years of heat and use, that sensing material can wear out, so the sensor becomes slower or less accurate.

Term

injectors

"...and also injectors because it had three of the injectors that were, they were starting to leak. So as you go, things pile up."

Fuel injectors are the parts that spray fuel into the engine. If they start leaking or don’t spray correctly, the engine can run rough and may misfire. Over time, that can make other problems show up too, so repairs can “pile up.”

Concept

diagnostic trouble codes (slow response)

"...you'll get a slow response code in them that if it's not caused by something else like a mass air flow or a vacuum leak, yeah, you can get that. So it's, it's probably time to replace them..."

Cars store warning codes when sensors don’t behave the way they should. A “slow response” code can mean the oxygen sensor is getting old, but it can also happen if something else is wrong (like air leaks or a bad air sensor). Good diagnosis checks the likely causes before swapping parts.

Term

vacuum leak

"...you'll get a slow response code in them that if it's not caused by something else like a mass air flow or a vacuum leak, yeah, you can get that."

A vacuum leak is like a small air leak in the engine system. It can make the engine run with the wrong fuel/air mix, which can trigger warning lights. That’s why mechanics consider vacuum leaks when they see certain sensor codes.

Company

car-part.com

"check out car-part.com. It's fast and it's easy. Over 200 million parts strong all across North America... Whether it's an engine, transmission, doors, seats, or wheels, you can find them on car-part.com."

Car-part.com is a website where you can buy used car parts from junkyards. It can help you find parts that fit your specific car, which can save money versus buying new.

Concept

buying recycled

"Whichever you choose, buying recycled is good for the environment and good for your wallet."

Recycled parts are used parts from cars that were taken apart. They often cost less than new parts and are better for the environment because they don’t require making everything from scratch.

Company

Berkeley One Classics

"For 50 years, Berkeley One Classics has ensured a wide range of vehicles from sports cars and rare exotic cars to antique vehicles... They also have discounts for car club members."

Berkeley One Classics is an insurance company that specializes in classic and specialty vehicles. They’re pitching coverage and discounts for people who own cars that may not fit standard insurance categories.

Term

snow tires

"Maybe that person is you or maybe you want a set of spare wheels that you can install on your vehicle over the winter months with snow tires to avoid damaging your nice summer wheels."

Snow tires are tires made for winter weather so your car grips better on snow and ice. Using a separate set (often on spare wheels) helps keep your regular summer wheels from getting beat up.

Company

Road ready wheels

"Road ready wheels has replacement wheels for many OEM manufacturers at substantial cost savings. These wheels look and perform like OEM wheels so save money and go with road ready wheels when you need a replacement."

Road ready wheels is a company selling replacement wheels for your car. They’re being marketed as a lower-cost option when your wheels are damaged, leaking air, or corroded from road salt.

Term

corrosion

"Are you tired of needing to add air to your tires every few days because your wheels have been eaten away by road salt and corrosion?"

Corrosion is rust or metal breakdown caused by things like road salt and moisture. In winter, it can damage wheels and lead to leaks or other wheel problems.

Term

factory steel wheels

"of road ready wheels will stop the leaks. Do you have factory steel wheels and have shopped in the seemingly endless and expensive aftermarket wheel scene not knowing what to get but you want a better look?"

Steel wheels are the basic wheels your car came with from the factory. They’re usually tough and not too expensive, but they can be heavier than nicer alloy wheels.

Term

aftermarket wheel scene

"Do you have factory steel wheels and have shopped in the seemingly endless and expensive aftermarket wheel scene not knowing what to get but you want a better look?"

Aftermarket wheels are wheels you buy that aren’t the ones your car came with. The tricky part is making sure they fit correctly and work with your car’s sensors.

Term

TPMS sensors

"These wheels are a direct fit so your factory caps and TPMS sensors will fit. Find out more and or yours at RoadReadyWheels.com."

TPMS sensors are little parts that monitor your tire pressure. If you change wheels, you need sensors that will work with your car so the tire-pressure warning doesn’t stay on.

Car

2001 Chevy pickup

"Let's talk to Dale. You're on the end of the hood show. Dale what can we do for you? I talked with you guys last week. I had that 2001 Chevy pickup that was losing electricity overnight."

They’re talking about a 2001 Chevrolet pickup that had an electrical problem. The story is used to explain how to diagnose the issue instead of guessing.

Concept

battery drain diagnosis vs quick fix

"Yes. And you had talked you know about well you got to run down all the circuits and everything and find out what you said as an alternative to just put a battery disconnect."

They’re basically saying: don’t just use a temporary trick to stop the problem—find out what’s actually causing the battery to drain. Otherwise, the real issue could still be there.

Term

battery disconnect

"Yes. And you had talked you know about well you got to run down all the circuits and everything and find out what you said as an alternative to just put a battery disconnect."

A battery disconnect is a way to fully turn off power from the battery. People use it when they suspect something is draining the battery, but they haven’t fixed the root problem yet.

Term

circuits

"Yes. And you had talked you know about well you got to run down all the circuits and everything and find out what you said as an alternative to just put a battery disconnect."

Circuits are the car’s wiring routes that carry electricity to different parts. Checking circuits helps find what’s pulling power when the car is supposed to be off.

Term

remote battery shutoffs

"Well I called you know like one of your sponsors is what that you know that does remote starts and stuff. I called them well do you have remote battery shutoffs. No they didn't and I called around a little bit"

Remote battery shutoffs let you turn off the car’s battery power without going to the battery. It can help stop battery drain when the car isn’t being used.

Term

negative side

"take your battery loose and on the negative side they send a post that you turn in to your battery you know so your looms can hook onto it"

A car battery has two terminals: one is the negative and one is the positive. The negative terminal is connected to the car’s ground, and disconnecting it first is a safer way to start electrical work.

Term

interrupter

"you know so you got an interrupter there and the other side the positive you just put another wire from the that little brain"

An “interrupter” here sounds like a switch that turns power on and off. People use this kind of thing to stop the battery from draining or to control when an electrical system gets power.

Term

positive

"you know so you got an interrupter there and the other side the positive you just put another wire from the that little brain"

The positive terminal is the battery’s main power output. If you connect something there, it can get power—but you have to be careful so you don’t create a dangerous wiring situation.

Term

illuminated grill emblems

"yeah so your emblem would light up when you oh wow listen to that gotta go fancy so okay just bottom line"

An “illuminated grill emblem” is a badge on the front of the car that lights up. It usually needs wiring and a secure mount so it works reliably and doesn’t get damaged by moisture.

Term

hack

"okay just bottom line thank you for the return call on that but it's you're you're using it and you're battery's not dead anymore it's obviously this is a hack it's not not a fix it's a hack to make it not have the problem"

In this context, a “hack” means a workaround that temporarily avoids a problem without addressing the root cause. It can be useful to restore functionality, but it may be unreliable, unsafe, or create new issues over time.

Term

battery storage

"well you because there are there are things in there they're gonna rely on that's battery storage that are gonna be affected here and there but"

Your car battery isn’t just for starting—it also keeps certain electronics powered. If you mess with how the battery is connected or isolated, some things may forget their settings, like the clock.

Term

fuel tank

"...I kind of touched on some things um I try to keep my alcohol content zero percent but what I put in the fuel tank is a little questionable because I'm cheap..."

The fuel tank is where your gas goes. The caller is basically saying they might be using something in the gas that isn’t ideal, and that can sometimes cause problems that show up later.

Car

Buick Enclave

"...nt camera potentially to add on to my 2015 Buick enclave that embeds into that hollow spot in the Buick g..."

The Buick Enclave is a larger SUV with three rows of seats, made for families or groups. The podcast is discussing adding a camera option to a 2015 model. That kind of upgrade usually involves fitting the camera hardware and making sure it works with the vehicle’s display system.

Brand

AC Delco warranty

"...maybe replacing it for me underneath the AC Delco warranty for like the third time..."

ACDelco is a GM parts brand. If you have an AC Delco warranty, it may cover repairs or replacements, which can save money when something like a TPMS sensor keeps failing.

Concept

calibrate

"...if it gets relocated to a different tire but they'll calibrate it I don't know how that works..."

Calibration is the car learning the new tire sensors after a tire/sensor change. Without it, the car might not show correct pressure or might keep warning you.

Term

tire pressure monitor sensor

"...they calibrate it I don't know how that works so yeah you need to tell me you're having problems with one... if your light's on just wait until you need tires... clean the wheel off as it gets in the sensor portion of the tire pressure monitor sensor..."

Cars use sensors in the tires to keep track of tire pressure. If a sensor is dead or can’t communicate, the car warns you with a light and the readings can be wrong or missing.

Concept

replacing sensors while tires are already off

"...then they come back to me and they get the tires done and we put in sensors it's so much cheaper to do it while the tires are already off the car..."

The host recommends doing TPMS sensor replacement during a tire change because the wheel is already dismounted. This reduces labor time and cost versus removing the tire twice, and it ensures the sensor is installed with proper cleaning and fitment.

Term

low battery

"...we put four sensors in that because they were all showing low battery and on cold days it would give you bars across the dash and not read the sensor at all..."

Many TPMS sensors are battery-powered and can report a low-battery condition before they fully fail. As the battery weakens—often more noticeable in cold weather—the sensor may transmit inconsistently, leading to missing or incorrect readings.

Term

stop leak

"...there's nothing that the tire can do to cause a sensor to go bad except for stop leak fix a flat you put that in the tire you're going to probably ruin the sensor..."

Some tire sealants can get into the sensor area and cause problems. The host is warning that if you use stop leak, you may end up needing a new tire sensor.

Term

fix a flat

"...except for stop leak fix a flat you put that in the tire you're going to probably ruin the sensor..."

“Fix a flat” is a common aerosol/sealant product used to temporarily seal punctures. The host claims it can ruin TPMS sensors because the sealant can reach the sensor portion of the tire/wheel assembly, making replacement necessary.

Term

scanner

"...there's nothing that could be happening on the car wise causing that sensor to fail the sensor's actually bad and they can read it when they hand out scanner they go around and read it..."

A scanner is a device the shop plugs in to check what the car is seeing. It can tell whether the tire sensor is actually sending data or if that sensor isn’t working.

Term

valve stem

"...it's 100% self-contained it's just connected right onto the valve stem there..."

The valve stem is where you put air in the tire. Some TPMS sensors are attached right to that valve area, so if they fail, it’s usually the sensor itself.

Term

400 megahertz

"...there's two sensors you've got a 315 megahertz and the 400 range megahertz on all cars..."

TPMS sensors use radio signals, and there are different common frequencies. If the sensor’s frequency doesn’t match what the car expects, the tire warning system may not work properly.

Company

Autel

"...we have a handheld alt autel device and we have boxes of these sensors that we can program per car..."

Autel makes tools that mechanics use to diagnose cars and program certain parts. Here, they’re using an Autel tool to set up tire sensors so the car can recognize them.

Term

315 megahertz

"...i think your car is 315 megahertz but you pre-program it and then you just put it in..."

315 MHz refers to the radio frequency TPMS sensors transmit on. Different regions and vehicle platforms use specific frequencies, so using the correct frequency sensor is important for the car to receive the signals.

Term

relearn on the car

"...you just put it in and then you do the relearn on the car and then it'll work... and i do the hit the relearn on the steering wheel and i program each one of these sensors..."

A TPMS “relearn” (or reset) is the process of teaching the vehicle which sensor IDs are installed. Even if sensors are physically installed, the car may still need a relearn procedure—often via the steering wheel controls—to start reading them correctly.

Term

ready sensors

"...they call them like ready sensors that's another brand... if you go to advanced auto parts... ask them what brands they have behind the counter..."

Some tire sensors come pre-set, so you can install them without special programming equipment. You may still need to reset the car’s tire system so it knows the sensors are there.

Term

hit the relearn on the steering wheel

"...so i just shake them and then i do the hit the relearn on the steering wheel and i program each one of these sensors..."

The car can be reset to recognize new tire sensors using the controls on the steering wheel. The steps depend on the car, but it’s usually a menu option or a button sequence.

Term

mounting and balancing four tires

"...i'll be good then i know okay i can go ahead and break these tires down and put these sensors in... why go to the work of mounting and balancing four tires..."

Mounting and balancing are the shop services required to install tires onto wheels and ensure smooth rotation. The segment highlights that doing this for multiple tires is expensive, so confirming the real cause (sensor vs module) before disassembly can reduce repair costs.

Term

wireless module

"...i've got a problem with the electronic receiver on the car the wireless module but on yours i i think you're gonna find you got a bad sensor..."

Your car has a receiver that listens for the tire sensors. If the sensors are fine but the car still can’t “hear” them, the problem could be that receiver module instead of the tires.

Term

breaking the tire

"but if you come in and say i just want a sensor put in 75 plus breaking the tire you have to buy 150 bucks a tire yeah and some places get that 75 dollar sensor that same one they're selling for 150 bucks"

“Breaking the tire” refers to dismounting a tire from the wheel so the sensor can be accessed or replaced. This adds labor and shop fees, which is why the total price can jump compared with just buying the sensor part.

Car

Hyundai Elantra

"yeah thanks for taking my call appreciate it you bet um i have a 2008 Hyundai Elantra that i actually talked to you guys a couple years ago about putting a timing belt in which i did do and it's now got 340 000 miles on it"

This is a 2008 Hyundai Elantra, and the caller is asking how long it can keep going after already doing major maintenance like a timing belt. When a car gets very high mileage, you have to decide which repairs are worth the cost.

Part

timing belt

"yeah thanks for taking my call appreciate it you bet um i have a 2008 Hyundai Elantra that i actually talked to you guys a couple years ago about putting a timing belt in which i did do"

The timing belt is a rubber belt that keeps the engine’s moving parts lined up. If it breaks, the engine can get badly damaged, so it’s a big maintenance item.

Concept

340,000 miles

"and it's now got 340 000 miles on it and so i'm uh my question i guess is what do you think the odds of it going to 400 and is it worth replacing the on my own some of the uh the suspension components"

Once a car has a ton of miles, more things start wearing out. The key question is whether it’s still a good deal to keep repairing it or if the money would be better spent elsewhere.

Part

suspension components

"and is it worth replacing the on my own some of the uh the suspension components on the kind of all around the car well i i'm gonna say you've officially involved yourself in a game"

Suspension parts help the car ride smoothly and keep the tires planted on the road. When they wear out, the car can feel bouncy or handle worse, and tires may wear unevenly.

Term

antifreeze

"yeah run this but go now it now the game isn't is it worth it now the game is how long can you go i know if it's quiet and it's not burning any oil and it's not using antifreeze i can't fiverr me and it wasn't burning antifreeze and it wasn't burning oil i'd"

Antifreeze is what keeps the engine from getting too hot or freezing in cold weather. If a car is losing it, that can mean a leak or a cooling problem.

Term

casey ultimate

"pour a bottle of casey ultimate in that cooling system... i'd put the casey'll in it yeah and then just go..."

This sounds like a cooling-system additive meant to slow leaks. It might help temporarily, but if the engine has a serious problem (like a head gasket), it won’t truly fix it.

Term

cooling system

"...pour a bottle of casey ultimate in that cooling system... if it's got a cooling system that's starting to break down... head gasket that's starting to leak..."

Your cooling system keeps the engine from getting too hot. If it’s failing, the engine can overheat and cause expensive damage.

Term

head gasket

"...if it's got a cooling system that's starting to break down and you got a head gasket that's starting to leak it's gonna kill it it's gonna die..."

The head gasket is a seal between the engine’s main parts. If it starts leaking, coolant and engine gases can mix, and the engine can overheat and die.

Term

junkyard

"...what's the worst case scenario when the car dies what's going to happen with it send it to a junkyard get 150 bucks..."

A junkyard is where cars get taken apart for parts. If your car is too expensive to fix, you can sometimes sell it there instead of paying for repairs.

Concept

"playing with house money" / negotiation risk framing

"...getting roughly uh when you go over a bump she uh chatter yeah i'd be worried about your safety in the engine right now if you've made it that far you're playing with house money fix those things..."

The hosts are using a risk-management mindset: if you’ve already invested in repairs and the car is still running, you treat remaining time as “extra” rather than guaranteeing a perfect fix. It’s a practical approach to deciding when to repair versus cut losses.

Term

control arms

"...make sure checking the ball joints um make sure on the control arms with that can you..."

Control arms locate the suspension and help manage wheel alignment and ride quality. If control arms or their bushings are worn, you can get vibration, clunks, and alignment issues that lead to premature tire wear.

Term

lower a arms

"...for what problem for suspension driver level for suspension i was thinking or yeah like the lower a arms ball joints..."

Lower control arms (often called “lower A-arms”) are a key suspension component that connects the chassis to the wheel assembly. Replacing worn lower arms can restore proper geometry and reduce noise/handling problems.

Term

struts

"...lower a arms ball joints struts and then uh shocks in the back..."

Struts are suspension components that combine shock damping with structural support (on many cars). Worn struts can cause bouncing, poor steering response, and uneven tire wear.

Term

shocks

"...struts and then uh shocks in the back just you said the key word better than nothing..."

Shocks damp suspension movement so the tires maintain contact with the road. If shocks are worn, you can get excessive body motion, reduced grip, and a rough ride.

Term

ball joints

"...comes in and says i was like hey your ball joints are bad yeah i just put those on well when two months ago where'd you get them amazon i'm like oh okay..."

Ball joints are parts in your suspension that help the wheel move up and down while still steering correctly. When they wear out, the ride can get noisy or sloppy and your tires may wear unevenly.

Company

dormantproducts.com

"...you can go to dormantproducts.com's website and if they sell it that means it's a part that commonly fails..."

The host references dormantproducts.com as a way to identify parts that commonly fail for a specific make and model. The underlying idea is that if a company sells a part specifically for that application, it’s often because it’s a frequent failure item.

Car

Chrysler Town and Country

"...just a clarification so i have an old one chrysler town and country 96 000 miles looking to just do my 100 000 mile maintenance um you guys would recommend a transmission flush..."

They’re talking about a 1996 Chrysler Town and Country and whether you should service the transmission at around 100,000 miles. The decision depends on how bad the transmission fluid looks and how the transmission has been treated.

Car

Chrysler Town

"...yep um just a clarification so i have an old one chrysler town and country 96 000 miles looking to just do my 10..."

The Chrysler Town & Country is a minivan, which is a family vehicle with sliding doors and lots of interior space. The podcast mentions an older one with 96,000 miles and talks about doing a maintenance task. That’s the kind of question owners ask when planning routine upkeep.

Term

transmission flush

"...you guys would recommend a transmission flush over a transmission drain and fill on that oh yeah yeah you want to get all of it out on that one..."

A transmission flush is a way to replace a lot of the old transmission fluid. Mechanics debate it because if the fluid is really neglected, changing it too aggressively can sometimes cause problems.

Term

transmission drain and fill

"...transmission flush over a transmission drain and fill on that oh yeah yeah you want to get all of it out on that one..."

A drain-and-fill is a simpler transmission service where they drain some of the old fluid and add new fluid. It usually changes less fluid than a flush, which can be safer if you’re not sure how the transmission has been maintained.

Term

transmission fluid

"...if the fluid is completely black because you've gone way too long and you've got it overheated 25 years no if you've got it way too long mean like you've run it overheated it turned it black but if it's just a darkish you know like a reddish orange color it should be fine for a flush..."

They’re using the look of the transmission fluid to judge whether the transmission is in good shape. If it’s very black from neglect, it may indicate trouble; if it’s only dark, a flush may be less risky.

Term

overheated

"...if you've gone way too long and you've got it overheated 25 years no if you've got it way too long mean like you've run it overheated it turned it black..."

If the transmission gets too hot, the fluid can break down faster. That can lead to dirty fluid and more wear inside the transmission.

Term

bypass valve

"...make sure there's not a bypass valve or a thermostatic control or something in line that's causing problems after that flush just make sure the flow is right..."

A bypass valve is like a built-in path that can route fluid around a section of the system. If it’s not allowing the fluid to circulate properly during a flush, the flush may not actually clean/replace what you want.

Term

thermostatic control

"...make sure there's not a bypass valve or a thermostatic control or something in line that's causing problems after that flush..."

Thermostatic control helps keep transmission fluid at the right temperature. If it prevents proper flow during a flush, the fluid might not get replaced as effectively as expected.

Term

Flow Max

"...just go get yourself a prescription for some of that what flow max or whatever just write down the old they don't do they don't have that for the transmission..."

Flow Max is mentioned as a product that can help with fluid flow. The takeaway is: if the transmission isn’t flowing correctly during service, you may need help getting it moving properly.

Car

2015 Buick

"hey guys i sure appreciate you taking my call you bet i've got a 2015 buick on core with the lego engine in it all plastic and i've got an overheating problem"

They’re talking about a 2015 Buick they own. The whole problem they’re trying to fix is the car overheating, which is a big deal because it can lead to expensive engine damage if it’s not solved.

Term

overheating problem

"hey guys i sure appreciate you taking my call you bet i've got a 2015 buick on core with the lego engine in it all plastic and i've got an overheating problem and my son's a mechanic"

Overheating means the engine is getting too hot. That can happen when the coolant isn’t circulating correctly or when parts like the thermostat or water pump aren’t working right.

Term

orange in there

"completely flush in the motor out put the orange in there and uh that seemed to solve the problem"

The caller switches from green antifreeze to “orange” coolant after flushing. Coolant color is often tied to chemistry (though color alone isn’t a perfect identifier), and the point here is that changing coolant type can affect corrosion control and heat transfer.

Part

PCV

"it it took on that little whistle where the pcv is built into the intake so i took it to my mechanic of 30 years and he replaced all that got rid of the whistle"

PCV is a system that helps keep the engine’s internal air pressure under control. If it’s not working right, it can cause odd noises and can make the engine run differently, which matters when you’re troubleshooting overheating.

Part

water pump

"i decided well the water pump was making a little grumbly sound so we put a new water pump on it and then we put new thermostat in it"

The water pump moves coolant through the engine to carry heat away. If it’s weak or failing, the car can overheat when you drive but may seem okay while idling.

Term

metal thermostats as opposed to a plastic one

"my fourth thermostat in it i got one of the metal thermostats as opposed to a plastic one still does the same thing"

Thermostats can be built with different materials, and the internal design can affect how reliably they open/close and how they respond to heat. The caller tried a metal thermostat to address repeat overheating, suggesting the original thermostat type or spec may not have been resolving the root cause.

Concept

diagnosis trap: replacing parts without fixing the root cause

"still does the same thing and i mean i'm i'm in so far deep into this car now that i i'm just like i've been all over the internet every youtube video there's very little about these things on there because it'll break keeps saying replace the thermos ... if you pull over and leave it running does it cool down uh yes and no sometimes it will sometimes it won't"

They’ve already replaced several parts, but the problem keeps coming back when they drive. That’s a sign the real cause might be something else, and just swapping parts can cost money without solving it.

Term

P0597

"put this last thermostat on it it started throwing a p0597 which says replace the thermostat so well that's because it saw the temp the temperature fluctuate so much"

P0597 is an error code your car’s computer sets. It usually means the car thinks the thermostat isn’t controlling engine temperature correctly, so it may suggest replacing it.

Term

handheld temperature guns

"step one you need to get yourself one of those little handheld temperature guns the laser pointer and while the engine's running in the driveway idling check the each radiator hose in and out"

A laser temperature gun measures how hot something is from a distance. Here it’s used to see if the radiator is cooling the engine coolant properly by comparing two spots.

Term

radiator hose in and out

"idling check the each radiator hose in and out and make sure you've got a good temperature drop across the radiator if you find it's 215 going in and 212 coming out with the fans running that's not enough that radiator is plugged"

You measure the temperature where coolant goes into the radiator and where it leaves. If the temperatures don’t change much, the radiator may not be cooling the coolant.

Concept

exhaust gas check of the coolant

"but before you go putting the radiator in you need to do the exhaust gas check of the coolant to make sure it doesn't have a head gasket out that could be restricting the coolant flow causing those readings because there's no actual coolant flowing"

This test checks whether exhaust gases are getting into the coolant. If they are, it can mean the head gasket is leaking, and that can mess up cooling and cause overheating.

Term

coolant flow

"restricting the coolant flow causing those readings because there's no actual coolant flowing it's just sitting there getting hot so check the exhaust gases"

Coolant flow is how well coolant moves through the engine to carry heat away. If flow is blocked, the engine can get hot even if parts like the radiator seem fine.

Term

temperature in and out

"that they're about 50 bucks pick that up try it and then check that temperature in and out and that'll tell you if it's an engine or put a bottle of kasey on it"

You compare the coolant temperature going into the radiator versus leaving it. If they’re almost the same, the radiator may not be cooling properly.
