The Car Show with Dane Donovan - 4/25/2026
About this episode
Dane Donovan opens with community updates and then pivots into practical maintenance warnings for summer. He discusses possible oil supply strain—no panic, but consider stocking if you change your own oil. With Cincinnati weather swinging fast, he urges listeners to test A/C now and explains why R-1234yf refrigerant is expensive and why A/C repairs often involve pressure/vacuum testing, dye, and multiple visits to find slow leaks. Callers cover vibrations (often drive shafts), clutch-carpet wear from high heels, transmission fluid “drain and fill” vs flush, a mysterious “wet belt” engine claim, and sunroof-related water intrusion.
Dane Donovan discusses car maintenance and repair. He talks about the importance of checking tire pressure and fluids, especially with the upcoming warmer weather. Dane also shares a personal story about his own car troubles and how he learned to replace his drive shaft. He answers listener questions, including one about a Honda CRV with a vibration issue and another about a Toyota Tacoma's potential maintenance needs. Additionally, Dane recommends a local business, Water Doctor Cincinnati, for fixing water leaks in vehicles.

checking the tire pressure
"So perfect day to be out and uh, you know, getting underneath that hood, checking the you know, checking the tire pressure, checking you know, your fluids, which we talk about all the time on this show."
Tire pressure is how much air is in your tires. If it’s too low or too high, the car won’t handle as well and the tires can wear out faster.
Tire pressure affects grip, ride comfort, and fuel economy. Checking it regularly helps ensure the tires are inflated to the vehicle’s recommended spec, which can also improve tire wear.
checking your fluids
"...checking the tire pressure, checking you know, your fluids, which we talk about all the time on this show."
Your car needs different liquids to work correctly. Checking fluid levels helps you catch problems early—like low oil or low coolant—before they turn into expensive repairs.
“Fluids” usually means items like engine oil, coolant, brake fluid, power steering fluid (if equipped), and windshield washer fluid. Keeping them at proper levels helps prevent overheating, brake issues, and component wear.
supply issue / back-ordered parts (oil)
"We're you know, orders are already getting back filled because because of the supply... No need to go panic and rush the stores. But we do need to think ahead... if we do have a supply issue..."
They’re saying oil might be harder to find for a while because of supply problems. If that happens, it’s smart to plan ahead so your car doesn’t miss maintenance.
The hosts are talking about a supply-chain problem that can lead to delays and back-ordered automotive consumables like engine oil. When supply tightens, it can become harder to buy what you need for routine maintenance, so planning ahead matters.
stock up a month or two
"Maybe if you change your own oil at home, maybe stock up a little bit... maybe a month or two, you know, just just in case... But we do need to think ahead..."
They’re recommending buying a little extra oil ahead of time so you’re not stuck later if stores run short. It’s meant to be a small backup, not a huge stockpile.
The hosts suggest keeping a small buffer of consumables (specifically engine oil) in case future availability becomes limited. This is a practical “just-in-case” approach to maintenance items rather than panic buying.
engine oil
"Maybe if you change your own oil at home, maybe stock up a little bit... we want to make sure that we protect our cars... making sure that the car has oil in it."
Engine oil is what keeps the engine parts from grinding against each other. The hosts are basically saying: make sure you have oil so you can keep your car maintained.
Engine oil is the lubricant that keeps internal engine parts from wearing out by reducing friction and carrying heat away. The episode emphasizes that having oil available (and keeping the car topped up) is essential for keeping vehicles running reliably.
gas prices are through the roof
"Okay, we all know that gas prices are through the roof. We know that, you know, oil's an issue..."
They’re saying gas is really expensive right now. When fuel costs jump, people tend to drive differently and pay more attention to efficiency.
“Gas prices through the roof” refers to unusually high fuel costs, which can change driving behavior and increase the importance of fuel economy. While not a technical car term, it’s a relevant ownership context that often affects how people plan trips and maintenance.
air conditioning (A/C)
"There's going to be a run on batteries, on alternators, on air conditioning, right."
Air conditioning is what cools the inside of the car. When it gets hot fast, people notice if the A/C isn’t working well and may need service.
A/C is the system that cools the cabin using refrigerant and a compressor. The episode implies that as temperatures rise, demand for A/C performance increases, which can lead to more service issues or parts sales.
batteries
"There's going to be a run on batteries, on alternators, on air conditioning, right."
A car battery provides starting power and supports the electrical system when the engine isn’t running or during high-demand moments. Temperature swings can affect battery performance, which is why the hosts expect more battery-related issues during seasonal changes.
alternators
"There's going to be a run on batteries, on alternators, on air conditioning..."
The alternator is what keeps your car’s battery charged while you drive and powers the car’s electronics. They’re saying hot/cold weather can make electrical systems work harder.
An alternator is the engine-driven generator that powers the vehicle’s electrical system and recharges the battery. The hosts connect weather swings to increased demand on electrical systems, which can make alternator and battery health more noticeable.
R-1234yf
"The other thing that I want to put on your radar is understand that a lot of these new cars, okay, have a free on it. It's called one two, three, four YF and it is very expensive... if you have One two three four yf you're looking at at least three hundred and fifty dollars..."
R-1234yf is the refrigerant used in many newer cars’ AC systems. It’s the “cooling chemical,” and it can be pricey, so recharging the AC can cost a lot more than older cars.
R-1234yf is a newer refrigerant used in many modern cars because it has a lower environmental impact than older refrigerants. It’s often significantly more expensive, so an AC recharge can cost much more, especially if leaks are frequent or hard to locate.
R-134a
"You know, a standard if you have a if you have R one thirty four, you know it's typically dependent upon how much free on. It's called one two, three, four YF..."
R-134a is the chemical inside your car’s AC that makes it cool. If your AC is low, the shop adds more of this refrigerant.
R-134a is a common refrigerant used in many older automotive AC systems. Shops often charge by refrigerant type, and R-134a is typically cheaper than newer refrigerants, which is why the speaker contrasts costs.
refrigerant leaks causing repeat AC recharge costs
"Well you have the new free on and is it is a lot more expensive... We put a dye in there... but that's not always the case, right, and then unfortunately we're charging it up again for three hundred and fifty dollars."
If your AC keeps losing its cooling chemical, adding more fixes it temporarily. If the leak isn’t repaired, you’ll likely have to pay again later.
If an AC system is losing refrigerant, simply recharging it treats the symptom, not the cause. Over time, the refrigerant level drops again, leading to repeat service visits—especially expensive when the car uses costly refrigerants like R-1234yf.
AC leak dye
"We put a dye in there, but then potentially, you know, six months later or six weeks later, you're out of free on again and we're putting hopefully with us putting the die in there, we're able to find the leak, but that's not always the case..."
Leak dye is a special additive that helps a mechanic find where the AC refrigerant is escaping. If the leak is hard to spot, you might still end up paying to recharge the AC again.
AC leak dye is added to the refrigerant system so technicians can later locate where the refrigerant escaped. It can help confirm the leak source, but it doesn’t always make the leak easy to find, which can lead to repeat recharges.
phone lines are wide open
"Okay, the number call five one, three, seven, four nine fifty five hundred. The phone lines are wide open... So uh, again, the phone lines are wide open five one, three, seven, five hundred."
They’re inviting listeners to call in with questions about their cars. It’s basically the “call-in” part of the show.
The hosts are taking listener calls during the show. This is a common radio format segment where advice and questions about car problems, maintenance, or buying decisions come directly from the audience.
smart maintenance
"Your car isn't just a machine, it's your daily partner, and with new cars becoming more expensive than ever, smart maintenance for your current vehicle just makes sense."
Smart maintenance just means taking care of your car before something breaks. If you check things like fluids, tires, and brakes on time, you’re less likely to get stuck—especially when you’re traveling.
“Smart maintenance” is the idea of keeping a car reliable by following the right service schedule and addressing small issues early. Instead of waiting for a breakdown, you do preventive checks so repairs are cheaper and the car is less likely to fail on a trip.
free on
"Coolant keeps the engine cool. Freeon keeps the air conditioning cold... So free on is a gas... because the gas is pressurized, it's always under pressure..."
“Freon” is the refrigerant gas that makes the A/C cool. You can’t just add any can—your car needs the right type and the right amount, or the A/C won’t cool properly.
“Freon” is commonly used as a generic name for refrigerant, the pressurized gas used in an A/C system. Modern cars use specific refrigerants (often labeled on the A/C service port), and the technician must use the correct one and charge it to the right amount for the system to work.
vacuum test
"...we have to hook that up to a system, suck it down to find out what what freeon was in the system, right, do a vacuum test to make sure that the system is holding vacuum right... If it passes that test, then we fill it back up."
Before adding refrigerant, a shop pulls a vacuum on the A/C lines to make sure there are no leaks. If the vacuum doesn’t hold, refrigerant will escape later and the A/C won’t work right.
A vacuum test (pulling a vacuum on the A/C system) checks for leaks and verifies the system can hold vacuum before charging with refrigerant. This step helps ensure moisture and air are removed and that the system won’t lose refrigerant after service.
A/C refrigerant charge (right amount)
"...I would recommend now you can't stop at a gas station or something like that and get a can of a free on... you've got to make sure that you put the right amount... if you put too much free on... it won't work. If you don't put enough... it won't work."
A/C systems must be charged with the correct refrigerant amount; too little or too much refrigerant can prevent proper cooling and can stress components. Because each vehicle’s system volume and design differ, technicians use measured charging and verification steps rather than “topping off.”
compressor
"...we'll put it in there and then we'll test the system. Then we can check to see if the compressor is doing what it needs to. We're checking to make sure we don't see any major leaks."
The compressor is the “pump” of the A/C system. It squeezes the refrigerant so it can move through the system and pull heat out of the cabin.
The A/C compressor pressurizes the refrigerant and circulates it through the system, enabling heat transfer. During diagnosis, technicians often verify compressor operation and look for symptoms like low cooling performance or pressure/temperature mismatches.
black light
"So we put a dye in there to verify and make sure that you know, if there is a leak, we can find it with a black light... with a green dye... with a black light"
A black light is used to reveal fluorescent dye that was added to the AC system. The dye glows under UV light, making the leak location visible on components, fittings, or hoses. This method is commonly used when leaks are slow and hard to spot by inspection alone.
AC leak diagnosis can require multiple visits
"And sometimes that might take one or two or three visits before we can find it... it can be stressful and it can absolutely with the new stuff absolutely be expensive."
If the leak is small, it may not be obvious right away. The mechanic might need to refill the AC and check again later until they can see the dye at the leak spot. That’s why it can take more than one visit.
Slow AC leaks often don’t show up immediately, so diagnosis can take repeated testing and re-checking. The process typically involves recharging the system, adding dye, and then inspecting with a black light until the leak source is found. This is why repairs can feel drawn out and expensive even when the shop is doing the right steps.
recharge-and-trace process (like an inner tube)
"No, we didn't fix anything. We filled it back up... It's just like an inner tube... We have to fill it back up to try to find where it leaked out at."
It’s similar to a tire or inner tube that slowly loses air—you have to put air back in before you can find the hole. For AC, the mechanic refills the system so the dye can travel to the leak. Then they can pinpoint and fix the real problem.
The speaker compares a leaking AC system to an inner tube: you can’t tell where the air went until you add pressure (recharge) and then look for the escape point. In practice, the shop refills the refrigerant so the dye can circulate and reveal the leak location. Only after identifying the leak can the underlying problem be fixed.
AC
"...a lot of times we'll charge that AC and you know, they call back three weeks later..."
“AC” here means the car’s air-conditioning system. If it leaks, the refrigerant level drops and the AC won’t work well until it’s fixed and recharged again.
In this context, “AC” means the vehicle’s air-conditioning system. When it’s not cooling properly, shops may recharge refrigerant, but leaks can cause the system to lose pressure again.
AC recharge without finding the leak
"...a lot of times we'll charge that AC... they call back three weeks later... Well, we didn't fix anything. We filled it back up..."
Sometimes a shop just refills the AC refrigerant but doesn’t fix the leak. Since the system is still pressurized, the refrigerant can leak out again and the AC stops working.
The hosts describe a common AC repair failure mode: recharging refrigerant without locating and repairing the leak. Because the system stays under pressure, it can leak out again quickly, leading to repeat callbacks.
condenser
"...let's say the condenser's leaking, which is in front of the radiator, in front of the bumper..."
The condenser is a heat-exchanger for the car’s air conditioning. It sits at the front of the car and can get hit by rocks or wear out, which can cause the AC to leak.
The condenser is part of the AC system located in front of the radiator. It rejects heat from the refrigerant, and it can be damaged or corrode from road debris, leading to refrigerant leaks.
Honda Crv
"...he had a on the CRV and he was chasing a vibration... possibly into transmission."
A Honda CR-V is the vehicle in the story. The caller thought the vibration might be from the transmission, but the shop discussion points toward the drive shaft/driveline.
The Honda CR-V is mentioned as the vehicle where the caller experienced a vibration. The discussion suggests the vibration could be related to the driveline (drive shaft) rather than only the transmission.
drive shaft
"...he was chasing a vibration... thinking it's possibly into transmission... If that thing's all well drive... it's got a drive shaft..."
The drive shaft is the part that sends power from the drivetrain to the wheels. If it’s worn or out of balance, it can cause shaking or vibration.
A drive shaft transfers rotational power from the transmission to the differential/axles, especially on vehicles with rear-wheel drive or all-wheel drive. Vibration can come from imbalance, worn components, or issues in the driveline.
road force balanced
"...I did new tires, made sure they were roads force balanced..."
Road force balancing is a more advanced way to balance tires by checking how they act while rolling under load. It helps fix vibration that can happen even after a basic balance.
Road force balancing is a tire balancing method that accounts for how a tire and wheel behave under load while rolling. It can reduce vibration that standard balancing might miss, especially when tires have irregularities.
tie rod ends
"...I did new tires, made sure they were roads force balanced, went ahead and replaced the tyrod ends, you know, made sure it was lined up correctly..."
Tie rod ends are steering parts that help control how the wheels point. If they’re worn, they can contribute to vibration or a shaky feel, so replacing them can help rule out steering causes.
Tie rod ends connect the steering linkage to the steering components and allow precise wheel alignment. Worn tie rod ends can cause steering-related vibration or instability, so replacing them is part of diagnosing vibration complaints.
carrier bearing
"...replaced the tyrod ends... ended up being my drive shaft... there was no leakage or nothing from that little carrier bearing in the middle of the draft shaft. ...but it was vibrating."
The carrier bearing helps hold the drive shaft in the right position. If it’s worn, the car can vibrate even if you don’t hear grinding or see obvious damage.
A carrier bearing supports the drive shaft and helps keep it aligned while it spins. Even if it isn’t making noise or leaking, a worn carrier bearing can still contribute to vibration.
all wheel drive
"did he say it was all wheel drive? Okay, no, it wasn't even making well. And some of them, yeah, but some of them are just two wheel drive."
All-wheel drive means the car can send power to both the front and rear wheels. That helps the car grip better when roads are slippery, but it can be more complicated to maintain.
All-wheel drive (AWD) means power is sent to more than just the front or rear axle, typically both axles. It’s used to improve traction in low-grip conditions, but it can add complexity and cost compared with two-wheel drive.
universal joints
"the you joints in those drive shafts go bad, and those the you to do. Yeah, and those and those drive shafts are not uh serviceable."
Universal joints are the flexible couplers inside the drive line that let the shaft keep turning even when parts move at different angles. If they wear out, the car can start making noise or feel rough, and sometimes you have to replace the whole drive shaft.
Universal joints (U-joints) allow a drive shaft to transmit torque while accommodating movement and angles between drivetrain components. When U-joints wear, you can get vibration, noise, or driveline clunking, and on some vehicles they’re not sold separately from the drive shaft.
non-serviceable driveline components
"and those and those drive shafts are not uh serviceable. You have to replace the entire drive shaft."
On some cars, the small worn-out part inside a drivetrain assembly can’t be replaced by itself. Instead, the shop has to replace the whole assembly, which costs more.
Some driveline parts are designed as sealed assemblies, meaning the worn component isn’t intended to be replaced individually. That drives up repair cost because the fix is to replace the entire assembly (like a complete drive shaft) instead of a single joint.
Honda Cord
"... friend. She has a twenty fourteen twenty fifteen Honda Cord five speed. She she only drives about ten minutes..."
The Honda Accord is a regular family car (a sedan) made for everyday driving. It’s designed to be easy to live with, especially for short trips like errands or commuting. The podcast is mentioning it because of how someone uses their Accord day to day.
The Honda Accord is a mid-size sedan known for being practical and comfortable for everyday driving. It often comes up in conversations because it’s a common choice for commuters and families, and it’s typically discussed in terms of long-term ownership and ease of use. In this podcast context, it’s mentioned alongside a specific Accord model and driving pattern, which is relevant to how the car fits real-world use.
clutch pedal floor
"She likes to wear high heels to work and she doesn't want to wear sneakers. She's got a problem with the clutch pedal floor where she's worn through the carpet into the jute down to the floorboard. It's I know, it's a very it's a non unusual question."
They’re describing the spot on the floor where the clutch pedal is. If the carpet is worn through there, it can expose the floor underneath and cause drafts, noise, or even moisture problems.
“Clutch pedal floor” refers to the area of the cabin beneath and around the clutch pedal where the driver’s foot rests and where wear can occur. If the carpet is worn through down to the floorboard, it can lead to exposed insulation, water intrusion, and a more uncomfortable or noisier cabin.
jute
"She's got a problem with the clutch pedal floor where she's worn through the carpet into the jute down to the floorboard. It's I know, it's a very it's a non unusual question."
Jute is the thick, fibrous padding under the carpet that helps with sound and insulation. If it’s worn down or exposed, the car can get noisier and the area can be more vulnerable to moisture.
Jute is a natural-fiber sound-deadening and insulation material used under carpets in many cars. When it gets compressed or damaged—like from heavy wear at the clutch pedal—it can reduce noise insulation and can hold moisture if the carpet is compromised.
WeatherTech mats
"And is there or do you know? I'll listen next week. Do you know any customers? I use weather Tech, mats Whebber, she uses chits. A Honda so she can use. Factory."
WeatherTech makes aftermarket floor mats/liners that are shaped to fit the car. They help protect the carpet from getting ruined by dirt, water, and everyday wear.
WeatherTech is an aftermarket brand known for molded floor liners designed to protect factory carpeting from dirt, water, and wear. In cases like worn pedal-area carpets, quality floor liners can help prevent further damage by taking the abuse instead of the original carpet.
factory mats
"I use weather Tech, mats Whebber, she uses chits. A Honda so she can use. Factory. But do you know obviously outside of having to"
“Factory mats” are the floor mats that came with the car from the manufacturer. They’re usually a perfect fit, but some people switch to aftermarket mats for extra protection.
“Factory” mats means the original equipment manufacturer (OEM) floor mats that came with the car. OEM mats can fit perfectly, but some owners still prefer aftermarket liners if they want deeper coverage or more durable protection.
Floorboard wear from foot traffic (heels)
"That that that is a unique situation. Somebody who wears heels every day and puts a hole all the way down to the metal of the car. And he did."
They’re talking about a car floor getting worn through because someone’s heels rub on it every day. When it goes all the way to the metal, it can cause rust and you’ll likely need protection or repair.
The speakers describe a “unique situation” where someone wearing heels every day wears through the floorboard down to bare metal. This is a form of localized, mechanical abrasion that can lead to corrosion and interior damage if not addressed.
AC system leak-down over time
"...let's say there aren't any leaks, aren't any problems... but the stuff whatever, the three on eventually oozes out naturally anyhow at some point... the seals and the gaskets in the AC system will then allow... it's a pressurized system, it will eventually allow the the the gas to you know, sneak out of those seals..."
Air-conditioning doesn’t always fail suddenly. Over years, tiny leaks can develop in the seals and hoses, so the refrigerant slowly runs low and the A/C stops working well.
Even if an A/C system has no obvious problem today, refrigerant can slowly escape over time through aging seals and gaskets. Because the system is pressurized, small leaks can let refrigerant “sneak out,” leading to reduced cooling or complete failure later.
refrigerant ("Freon")
"...if the compressor is working or not, if it doesn't, if I don't know if there's free on it, if there's a pressure switch on the compressor..."
The term “Freon” is commonly used to refer to the refrigerant used in A/C systems (even though modern systems may use different refrigerants). Refrigerant amount is critical because the compressor and pressure switch rely on proper charge to function correctly.
refrigerant dye
"...we do, you know, put an oil and a dye in there. So in two weeks when you bring back... that leak has presented itself, and then we can figure out what we need to do..."
Sometimes you can’t find an A/C leak just by looking. A technician can add a special dye, then later check for where it shows up to find the leak.
Refrigerant dye is added to the A/C system so that, when the refrigerant leaks out, the dye marks the leak location. This helps technicians pinpoint where the refrigerant escaped when they can’t easily see the problem.
A/C leak diagnosis with dye and time
"...we don't know where it leaked out at, so we do, you know, put an oil and a dye in there. So in two weeks when you bring back... hopefully that leak has presented itself..."
They add something that makes the leak easier to spot, then wait a bit. When you come back, they look for the marked spot to know what part is leaking.
The diagnostic approach described is to add dye (and often oil) to the A/C system, then wait for the leak to appear. The technician uses the dye’s location to guide the repair, rather than guessing where the refrigerant is escaping.
recharging vs repairing the leak
"...they're like, you know, you fix my AC and now it doesn't work again. It's like, no, we didn't fix it. We just filled it back up."
The speaker emphasizes that refilling/recharging refrigerant may temporarily restore cooling, but it doesn’t fix the underlying leak. If the leak remains, the refrigerant will escape again and the A/C will fail later.
water pump
"...a compressor or an alternator, or a water pump or other things before they go bad."
The water pump moves coolant through the engine so it doesn’t overheat. If it fails, the engine can get too hot and cause serious problems.
The water pump circulates coolant through the engine to keep temperatures under control. A failing water pump can lead to overheating and potential engine damage if it’s not addressed.
preventive replacement vs replace when needed
"...there a point to where maybe some things should be replaced before they go bad... I would I wouldn't recommend replacing alternator, compressor or anything like that before it goes bad."
They’re basically saying: don’t just replace expensive parts “just because.” Instead, keep up with regular maintenance and fluids, and only replace parts when they actually show problems.
The hosts discuss whether it’s smart to replace components like the alternator, A/C compressor, or water pump before they fail. The takeaway is that routine maintenance (oil and fluid service) matters more than proactively replacing major parts on a fixed schedule unless there’s a known issue or warning signs.
Toyota Coma
"So it says here you have a twenty seventeen Toyota Coma."
They mention a 2017 Toyota, but the exact model name in the transcript (“Coma”) is unclear. The point of bringing it up is to talk about what maintenance items matter for that type of vehicle.
The transcript appears to reference a 2017 Toyota model, but the model name is transcribed as “Coma,” which doesn’t clearly match a known Toyota model. The discussion around seating/storage and drivetrain suggests they’re talking about a specific Toyota truck/SUV configuration, likely relevant to maintenance intervals and fluid checks.
oil change
"...making sure that you know the oil change regular, making sure all the fluids."
An oil change is when old engine oil is replaced with new oil. It helps keep the engine running smoothly and prevents extra wear.
An oil change replaces used engine oil with fresh oil to maintain lubrication and protect engine wear. Regular oil changes are one of the highest-impact maintenance items, especially as mileage increases.
power steering fluid
"...your coolant, your powasteering fluid, rear differential..."
Power steering fluid helps make steering easier. If it’s low or bad, steering can feel heavy and the system can wear out.
Power steering fluid helps transmit hydraulic pressure to assist steering effort. Low or degraded fluid can cause whining noises, stiff steering, or damage to the power steering system.
coolant
"...transmission fluid, your coolant, your powasteering fluid..."
Coolant (antifreeze) carries heat away from the engine and prevents freezing and corrosion. Keeping the correct coolant level and condition helps avoid overheating and protects the cooling system.
transmission fluid
"...you've got transmission fluid, your coolant, your powasteering fluid..."
Transmission fluid is the fluid that helps your transmission shift smoothly. If it gets old or low, shifting can feel rough and the transmission can wear out faster.
Transmission fluid lubricates and helps transfer hydraulic power in an automatic or manual transmission. Over time it can break down, leading to harsher shifting, overheating, or premature wear.
rear differential
"...rear differential, front differential, if it's. Four wheel drive."
The rear differential is what lets the two rear wheels turn at different speeds, especially in turns. It needs its own fluid so the gears stay lubricated.
The rear differential splits engine torque between the rear wheels and allows them to rotate at different speeds when turning. Differential fluid maintenance helps prevent wear and overheating in the gears.
front differential
"...rear differential, front differential, if it's. Four wheel drive."
The front differential helps the front wheels turn at different speeds when you corner. If the fluid isn’t maintained, the gears can wear out faster.
The front differential performs the same job as the rear differential, but for the front axle—splitting torque between front wheels. On four-wheel-drive vehicles, keeping front differential fluid fresh is important for smooth operation and gear longevity.
spark plug
"you Have you replaced the spark plug yet? Yes? Okay, what about the cool I do I do."
Spark plugs help your engine start and run by creating the spark that ignites fuel. If they get worn out, the engine can run rough or misfire. It’s a normal maintenance item.
Spark plugs are the ignition components that create the spark needed to ignite the air-fuel mixture in gasoline engines. They wear over time and can affect misfires, fuel economy, and drivability. The hosts mention replacing spark plugs as part of routine maintenance.
gradual fluid replacement to avoid "shocking" a neglected transmission
"...you know, just doing a drain and fill driving it and then you know, slowly introducing that fluid so you know, we're not shocking that transmission... So you want to slowly introduce that so you don't... get some of the particles... but not all of it because it's just too it's just too hard on it."
If you’ve gone a long time without changing transmission fluid, doing it all at once can cause problems. The hosts suggest changing it gradually so the transmission can adjust and you don’t stir up too much dirt at once. Repeating the service helps clean things out step-by-step.
The episode describes a common maintenance strategy: when transmission fluid has been overdue, you refresh it gradually. The goal is to reduce contaminants over time while minimizing the risk of stirring up debris that could affect valves, passages, or clutches. This approach is often paired with repeating drain-and-fill services across several intervals.
Donovan's Auto Center
"Way back in nineteen fifty eight, my grandfather opened Donovan's Auto entire Center right here in Cincinnati... Donovan's Auto entire Center is still Cincinnati's honest choice for auto repair... Three area locations."
This is the name of a local auto repair shop mentioned during the show’s advertisement. They’re saying they do honest repairs and have several locations. It’s not a car part or technical concept.
Donovan’s Auto Center is the family-owned auto repair business mentioned in the episode’s local ad read. The hosts emphasize “honest auto repair” and multiple Cincinnati-area locations. This is a branding/advertising reference rather than a technical automotive topic.
wet belt
"I was just reading General Motor. Chevrolet the past two years has been using a motor that has a wet belt in it for the Chevy tracks. I just didn't know if you knew anything about those engines..."
A wet belt is a rubber belt that works while it’s sitting in engine oil. That oil helps protect it, but it can also mean the engine is designed differently and belt service may be more complicated.
A “wet belt” is a timing/drive belt that runs inside the engine oil bath instead of in open air. Keeping the belt lubricated can reduce noise and wear, but it also changes how the belt is serviced and what failure modes to watch for.
engine longevity / belt durability
"I just didn't know if you knew anything about those engines, if they're long, you know, longevity is good, or you know why a belt not moversus a chain?"
The caller’s core concern is longevity—whether a wet-belt design improves durability compared with other belt arrangements. Belt life is influenced by materials, lubrication, heat, and contamination, so a design change can affect maintenance expectations.
belt vs chain (timing drive comparison)
"I just didn't know if you knew anything about those engines... longevity is good, or you know why a belt not moversus a chain?"
They’re comparing belts and chains inside engines. Both can drive important components, but they tend to wear differently and can lead to different maintenance schedules.
The transcript raises the common comparison between belt-driven and chain-driven engine timing/drive systems. Belts and chains differ in typical wear characteristics, noise, and service needs—so manufacturers may choose one based on cost, packaging, and expected lifespan.
serpentine belt
"I just googled because I was wondering if they were still using serpentine belt, god belt, so to speak."
A serpentine belt is the main belt that powers several engine accessories at once. They’re asking whether the newer “wet belt” idea replaced the older, more common belt setup.
A serpentine belt is the long, single belt that drives multiple accessories (like the alternator and power steering pump) on many vehicles. The caller is wondering whether GM/ Chevrolet moved away from this familiar belt approach toward a wet-belt design.
timing belt
"you got. It's just like a timing belt. You got to go in there and take everything apart."
A timing belt is what keeps the engine’s moving parts “in sync.” If it breaks, the valves can hit the pistons, which can destroy the engine—so it needs scheduled replacement.
A timing belt synchronizes the crankshaft and camshaft(s) so the engine’s valves open at the correct time. Because it’s a wear item, it typically requires periodic replacement, and failure can cause severe engine damage.
oil maintenance
"It said that the oil maintenance is very critical to the how long they can last. So you want to."
Oil maintenance means changing the oil on time and using the right oil. Clean oil helps protect the engine and keeps things from wearing out too fast.
Oil maintenance is critical because engine oil affects lubrication, cooling, and the condition of internal components. If oil change intervals are ignored or oil quality is poor, it can accelerate wear and shorten the life of parts that depend on clean lubrication.
sun roof
"A sun roof, it's not leacoing. My carpet is soaked... nine out of ten times when there is water intrusion in a vehicle, it is due to the sunroof. Now, your sunroof has drains, Okay, tubes that run down the A pillars and the B pillars... empty out on the ground."
A sunroof has seals and drain tubes. If the drains get clogged or disconnected, water can back up and end up soaking the carpet and headliner even if the roof itself seems fine.
A sunroof can leak even when it doesn’t look obviously broken because water often enters through the seals or around the opening and then travels inside the headliner. Many sunroofs rely on drain tubes that route water down the A- and B-pillars to the ground; if those drains clog or detach, water can soak carpets and spread across the cabin.
water intrusion diagnosis
"Oka, Okay, all right, so here's well most likely nine at it. Nine out of ten times when there is water intrusion in a vehicle, it is due to the sunroof... Now, again, nine out ten times, if there's water intrusion vehicle, it's coming from the sun roof or the panoramic sunroof..."
The hosts discuss a diagnostic rule of thumb: when a vehicle has interior soaking, the cause is often the sunroof (including panoramic sunroofs). They explain the mechanism—water entering the roof area and then following the drain path or leaking past seals—so listeners understand why carpets and headliners get wet.
A pillars and B pillars
"Now, your sunroof has drains, Okay, tubes that run down the A pillars and the B pillars... and empty out on the ground."
The A- and B-pillars are the vertical parts of the car’s body near the windshield and doors. Sunroof drain tubes often run down them, so if the tubes clog, water can end up inside the car.
The A- and B-pillars are structural vertical body sections that also commonly house hidden routing for water drainage. In sunroof systems, drain tubes often run down these pillars to move water away from the cabin; if they clog, water can overflow into interior trim.
drains
"Now, your sunroof has drains, Okay, tubes that run down the A pillars and the B pillars... What happens is debris, dirt, soot get into those drains... a lot of times the product that they use for the drains will over time and age will shrink right and contract and then disconnect itself..."
Sunroof drains are the tubes and channels that carry water away from the sunroof area. The transcript describes how debris can clog these drains, or how aging sealant/material can shrink and disconnect the drain path—both leading to water intrusion.
oil supplier
"...I started the show with, hey, just think about you know, they're my oil supplier, saying that we're gonna probably run out of oil or have a supply issue. So think about that with your vehicle."
Engine oil is what keeps your engine lubricated. If you can’t get oil when you need it, it can delay maintenance—so it’s smart to plan ahead before a trip or a busy season.
The host mentions an “oil supplier” and the idea of running out or having a supply issue. For car owners, this is a reminder that engine oil is a consumable item and you should plan ahead so you can keep up with oil changes and top-offs.
pre-trip car readiness checklist
"...So think about that with your vehicle. If you're gonna go on a vacation this summer, you want to make sure your car is ready to go to hit the road. Make sure your tires are properly inflated..."
The host is talking about getting your car ready before a vacation. The big points are oil and making sure your tires are in good shape so you don’t get surprised on the road.
This segment is essentially a checklist for getting your car ready for summer travel: plan for oil availability, check tire pressure and tread, and ensure the car is road-ready. It’s a practical ownership topic rather than a deep technical one.
tires properly inflated
"If you're gonna go on a vacation this summer, you want to make sure your car is ready to go to hit the road. Make sure your tires are properly inflated and you have good you know, you know, tread, and make sure that car is ready to go."
Tire pressure matters. If your tires are too low or too high, they don’t grip the road as well and they wear out faster, so it’s worth checking before you drive far.
“Properly inflated” means setting tire pressure to the vehicle’s recommended spec. Correct pressure affects ride comfort, braking grip, fuel economy, and tire wear—especially important for long trips.
tread
"...Make sure your tires are properly inflated and you have good you know, you know, tread, and make sure that car is ready to go."
“Tread” refers to the rubber grooves on a tire that help channel water and provide traction. Worn tread reduces grip in rain and increases stopping distances, so checking tread depth is a key pre-trip safety step.
new tires
"I actually decided to put new tires on my car as well, So you know, you. Think about these things."
Replacing old tires with new ones can make your car safer and easier to control. It’s especially helpful before a long drive when you want maximum grip.
The host says he “decided to put new tires on my car as well,” which highlights the practical decision to replace tires before a trip. New tires can restore traction and reduce the risk of uneven wear or poor wet-weather performance.
