Essential Gear Every Modified Diesel Owner Needs to Carry
Tesla Semi
Car

Tesla Semi

The Tesla Semi is a large electric truck used to move freight. Instead of using diesel fuel, it runs on electricity stored in batteries. The podcast mentions semi trucks and breakdowns, which is relevant to how these vehicles perform in daily use.

Term

single rear wheel

It means there’s one tire on each side at the back, not two. That affects how the truck carries weight and rides over rough roads.

Term

dual rear wheel chassis

This describes a truck with two tires on each side at the back. It helps the truck handle heavy loads and can make the ride and grip better.

Term

13 speed

A 13-speed truck has lots of gear options. That helps the engine stay in the right RPM range when you’re driving a heavy rig.

Term

PT pump swaps

This is a modification to the diesel fuel pump system. The goal is usually to change how the engine gets fuel, often for more straightforward fueling and fewer emissions controls.

855 Cummins
Car

855 Cummins

Cummins 855 is an older diesel engine used in big trucks. In this story, they’re talking about converting its fuel system to a more mechanical style.

Term

mechanical injection

Mechanical injection means the diesel fuel system is controlled without modern electronics. People like it in some builds because it can be simpler and easier to modify.

Term

dyno

A dyno is a testing machine that measures how much power and torque a vehicle makes. It’s how you can confirm results after modifications.

Term

rear wheel torque

It means how much twisting force the truck is actually sending to the rear wheels. It’s a practical way to judge how strong the truck feels when you drive it.

Term

turbo blew

When someone says a “turbo blew,” they mean the turbocharger failed—often due to oil starvation, overspeed, bearing failure, or damage from debris. In a modified diesel context, turbo failures are a common roadside problem because the turbo is critical for boost.

Term

reverse rotation

“Reverse rotation” refers to a turbocharger variant whose compressor and turbine are designed to spin in the opposite direction from the more common setup. This matters for fitment and compatibility—if you install the wrong rotation turbo, it won’t produce the intended boost behavior.

Brand

Borg S 400s

BorgWarner (often shortened in speech) is a major turbocharger brand used on many performance and diesel builds. “S400” refers to the S400 turbo family, which is commonly associated with larger turbo setups aimed at higher boost and airflow.

Dodge Spirit
Car

Dodge Spirit

The Dodge Spirit is a regular passenger car made by Dodge. In the podcast, it sounds like someone had one and added performance parts to make it faster. That’s why it’s being mentioned with turbo-related details.

Brand

Garrett GT 55s

Garrett makes turbochargers. A turbo is a device that uses the engine’s exhaust to spin a fan that forces more air into the engine, which can boost power.

Part

boots and couplers

On turbo setups, “boots” and “couplers” are the rubber hoses and connectors that connect the air pipes. They help keep the pressurized air from leaking.

Concept

limp it

“Limp it” refers to driving a vehicle in a reduced-capability state after a failure, typically to get it to safety or a shop. On modified diesels, this often means avoiding full boost/load while the driver manages a temporary fix.

Term

fabrication

“Fabrication” here means making parts by hand—cutting and welding metal to build something that fits your vehicle.

Concept

Junker Dragtrik

“Junker Dragtrik” sounds like a specific custom diesel build. It’s the kind of project where the owner modifies the truck heavily for fast runs, not just normal street driving.

Term

five inch stack

On a diesel, a “stack” is a vertical pipe that changes airflow/exhaust routing. “Five inch” just means the pipe is about 5 inches wide.

Term

double wall

“Double wall” means the pipe is built with two layers. That extra layer helps it handle heat better and last longer under heavy use.

Term

Las Vegas Motor Speedway

This is a well-known racing track in Las Vegas. The hosts mention it to help you picture the tall exhaust “stack” on a drag truck.

Concept

break down in the middle of nowhere

They’re talking about getting stuck far from help and having to fix the truck with what you brought. With modified diesels, exhaust and pressure-related problems can be the hardest to patch quickly.

Term

stove pipe

“Stove pipe” is a slang term for a straight, stovepipe-style metal exhaust/pipe section. In the context here, it’s being used as an improvised part to route exhaust/stacking when stranded.

Term

silicone couplers

Silicone couplers are flexible connectors that join two pipe sections. They help the system stay together even with heat and movement.

Term

S curves

“S curves” means the pipe is bent in an S shape. Bends like that can make exhaust routing harder and may affect how smoothly gases flow.

Term

exhaust sealed up

When they say they didn’t “seal up” the exhaust, they mean the exhaust parts weren’t tight enough at the connections. That can cause leaks that let soot escape and can mess with how the emissions equipment works.

Term

filter

They’re talking about the diesel soot filter. It catches the smoky particles from the exhaust, and if it gets clogged or damaged, the truck can lose power and may need to be pulled or serviced.

Term

cold air

“Cold air” likely refers to using a cold-air intake or routing intake air to stay cooler, which can improve charge density and combustion efficiency. If the setup can’t use that cold-air path (or it’s blocked by fitment/exhaust issues), the engine may not perform as expected under load.

Term

T six flange

A flange is the part with bolt holes that connects two exhaust/turbo parts together. If the flange type doesn’t match, the parts won’t seal well and you can get leaks and soot.

Term

Borg 475

“Borg 475” is a turbocharger setup people use for diesel performance. The important part is that the turbo has specific mounting/flange shapes, so if you match the wrong parts, it won’t fit or seal correctly.

Term

HT three B

“HT three B” is a specific turbo variant name. In this conversation, they’re saying it doesn’t match the other turbo’s flange/connection style, which can lead to leaks.

Term

drill and tap

“Drill and tap” means making a hole and adding threads inside it so a bolt can screw in. If they’re talking about doing this for turbo mounting, it usually means the parts didn’t line up right.

Term

die grinder

A die grinder is a small handheld tool for grinding metal. If they had to grind the turbo to make holes line up, it’s a warning that the parts may not fit/seal as intended.

Term

soot leaks

Soot leaks are when smoky exhaust particles escape from a bad connection. That can make the soot filter clog faster and can hurt power.

Term

roadside fixes

Roadside fixes are the quick repairs you do when your truck breaks down on the side of the road. The idea is to get it running well enough to drive again or at least make it to town.

Term

lag

Lag is the delay you feel when you press the gas and the truck doesn’t speed up right away. With turbos, it’s often how long it takes for boost to build.

Term

turbos

Turbos are devices that use the engine’s exhaust to spin and push extra air into the engine. More air helps the diesel make more power, but it can also change how quickly it responds.

Term

stranded

“Stranded” means the truck won’t run or can’t move, so you’re stuck where you are. On modified diesels, certain failures can leave you without an easy fix.

Term

ran it out of fuel

If you run out of fuel, the diesel can’t keep burning because it’s not getting fuel. Sometimes air gets into the fuel lines, and you have to get the system primed again to restart.

Term

engine oil

They’re talking about adding engine oil into the fuel tank. That’s not the same as diesel fuel, and it can lead to problems like extra smoke and clogged or damaged fuel parts.

Term

sump

A sump is a low spot where fluid collects. In a diesel setup, it can help make sure fuel is available when the truck is moving around or when fuel supply is tight.

Term

diesel

Diesel is the fuel the engine is designed to burn. Using the wrong kind can cause the engine to run poorly or not at all.

Term

blow boots

On modified diesel setups, there are rubber seals/hoses that connect parts of the turbo/boost system. If they “blow,” they split or pop off, and you lose boost pressure.

Term

towing

Towing means pulling a heavy trailer, which makes the engine work harder for longer. That extra stress can overheat and strain the turbo/boost connections.

Term

ambient temperatures

Ambient temperature is just how hot the air is outside. When it’s very hot, the whole engine bay runs hotter, and the turbo/boost parts can get stressed more easily.

Term

making boosts

Boost is extra pressure from the turbo that pushes more air into the engine. More boost usually means more pressure on the rubber hoses/seals that connect the turbo system.

Term

tie wire

Tie wire is a thin wire you can twist to hold something in place. Here, it’s being used as a temporary fix to keep a rubber connection from coming apart.

Term

duct tape

Duct tape is a quick, temporary patch. It can help in a pinch, but it usually won’t last long on a hot, high-pressure turbo/boost connection.

Term

hot side

The “hot side” is the part of the turbo system that gets the hottest. Heat can damage the rubber/silicone couplers that seal the intake plumbing. Using better boots helps them survive that heat.

Term

intercooler boots

On a turbo diesel, the intercooler cools the compressed air before it goes into the engine. The “boots” are the heat-resistant rubber/silicone pieces that connect the intercooler to the pipes and keep everything sealed. If they’re weak, they can come loose on hot days or heavy pulls.

Term

sustaining more than 30 pounds

“30 pounds” means the turbo is pushing about 30 psi of extra pressure for a while. Holding that kind of boost builds up heat and stress on the hoses and clamps. If your boots aren’t strong enough, they can come off.

Term

compound

“Compound” here refers to running more than one turbo. That can make more boost and create more stress on the hoses and connections that carry the pressurized air. So the intercooler boots need to be better quality to keep from popping off.

Term

single turbo

A “single turbo” means the engine uses one turbocharger. Even if it’s not a fancy multi-turbo setup, hard work like towing up grades can get the intake parts very hot. If the intercooler boots aren’t good, they can soften and pop loose.

Term

boot torque

“Boot torque” just means tightening the clamp on a rubber protective cover to the right tightness. It helps keep the cover sealed and protected so dirt and water don’t get inside.

Term

clamps

Here, “clamps” are the metal bands that hold a rubber cover in place. If they’re not tight enough, the cover can loosen and let dirt in.

Term

spade

A “spade” is a type of electrical plug/connector shape. If it cracks, the alternator wiring may not connect reliably, which can affect charging.

Term

hot-wired

“Hot-wired” here means they used a temporary wire connection to bypass the broken connector so the truck would keep working. It’s a get-you-home fix, not a proper long-term repair.

Term

six speed

“Six-speed” means the truck has six gears. Using lower gears can raise RPM to slow the truck down using the engine.

Term

engine braking

Engine braking means you slow down by using the engine instead of just the brakes. Downshifting can raise RPM, and if it’s held too high, it can stress the engine.

Term

unloaded RPM above 3000

This is basically saying the engine was revving high while not really under load. Keeping RPM that high for too long can be hard on the engine.

Part

rod bolts

Rod bolts are the fasteners that hold the connecting rods to the crankshaft. If they come loose or fail, the engine can get badly damaged very quickly.

Concept

windowed the block

“Windowed the block” means the engine got so badly damaged that metal parts broke through the engine block. That’s usually a total engine failure, not a simple fix.

Term

LBZ

LBZ is a nickname/engine code for a particular Duramax diesel version. Enthusiasts use it to tell which generation they’re talking about, since different versions behave a bit differently.

Concept

hand roadside breakdowns

They’re talking about getting stuck on the side of the road and needing help. The idea is that modifications can increase the chances of problems, so you should be prepared with the right basics.

Term

OEM quality parts

OEM quality parts are made to match what the vehicle manufacturer originally designed. They’re contrasting that with aftermarket parts, which can be better or worse depending on the brand and design.

Term

aftermarket quality parts

Aftermarket parts are made by companies other than the vehicle maker. For modified diesels, some aftermarket parts are great, but others aren’t as well-engineered, so they can cause problems.

Term

CP3 pump

The CP3 pump is a key fuel system component on many diesel trucks. It helps pressurize fuel for the engine, and when you modify a diesel, people often upgrade or change how this pump works.

Term

high pressure fuel lines

These are the fuel pipes that send diesel to the engine using very high pressure. If one cracks or breaks, the engine may not run right—or at all. Having a spare can help you fix the truck roadside and keep from being stranded.

Term

rubber isolators

Rubber isolators are parts that help absorb vibration. If a fuel line is constantly shaking, it can eventually crack. The hosts are talking about using isolators (or bracing around them) to reduce that shaking.

Term

aftermarket portion

An aftermarket portion refers to fuel-system hardware that’s been replaced or added beyond the factory configuration. In this segment, the speaker points to a specific aftermarket section that “teed” two pumps together, which changes how the system vibrates and where stress concentrates. That can make certain failure points more likely than on stock setups.

Term

T that teased the two pumps together

A “T” is a connector that splits or combines fluid flow. In this case, it connects two pump lines together. Connectors can be stress points, so if they vibrate or aren’t braced well, lines can crack there.

Term

19 mill range

They’re talking about a tool size—about 19 mm. That matters because the right wrench/socket is needed to loosen and tighten the fittings when you swap a fuel line. It’s basically the “what size tool do I need” detail.

Term

11 sixteenths

That’s an inch-based tool size written as a fraction. The point is that some tool kits don’t include the larger sizes the speaker needs.

Term

five eighths

“Five eighths” is a fractional inch size for a wrench or socket. The speaker is saying many kits top out at that size.

Term

three quarter

“Three quarter” means 3/4-inch, which is a common large wrench/socket size. They want a kit that includes that bigger size.

Brand

GearWrench

GearWrench is a brand that makes hand tools like wrenches and sockets. The speaker picked it because the kit includes the sizes they need.

Term

Crescent wrench

A Crescent wrench is an adjustable wrench. You can set it to different bolt or nut sizes so you’re not stuck needing the exact tool size.

Term

channel locks

Channel locks are adjustable pliers. They grip parts tightly so you can loosen or tighten things when a wrench doesn’t work.

Term

lug nut

A lug nut is the nut that holds your wheel onto the car. If you ever need to change a tire, you need to be able to loosen and remove it.

Term

JV Weld

JV Weld is a strong glue/epoxy you can use for quick fixes. Here it’s used to patch a radiator leak so the truck can get by until you can fix it for real.

Term

turbo pipe

A turbo pipe is a tube that carries the pressurized air made by the turbo. If it comes loose or cracks, the engine can lose power because the boost can’t stay in the system.

Term

radiator

A radiator is the heat exchanger that removes heat from engine coolant before it recirculates. If a radiator fitting breaks or a hose pops off, coolant can leak quickly and the engine can overheat.

Term

hydro lock

Hydro lock is when liquid gets into the engine where it should only have air/fuel vapor. Since liquid can’t compress, it can cause major damage.

Term

MPT

MPT here means a specific type of screw thread used on plumbing-style fittings. If the thread is gone or damaged, it’s hard to make a tight seal.

Term

tapped

Tapping means cutting threads inside a hole so a screw or fitting can thread in. It’s a way to create a proper connection after damage.

98 12 valve long bed Dodge
Car

98 12 valve long bed Dodge

They’re talking about a Dodge truck with a Cummins diesel engine that has 12 valves per cylinder head. People like these engines because they make a lot of pulling power and are popular to modify.

Term

line rupture

A “line rupture” is when a hose or pipe that carries fluid suddenly bursts. That can cause leaks and can even lead to problems like overheating or not being able to drive.

Part

PDT transmission line

A transmission line is a hose/pipe that carries transmission fluid. If it breaks, the transmission can’t work correctly, so having a spare helps you get back on the road or track.

Part

spare torque converter

A torque converter is part of an automatic transmission that helps transfer power from the engine to the drivetrain. If it fails, the truck may not move correctly, so a spare can save a race day.

Term

ATF

ATF stands for automatic transmission fluid. It’s the fluid that keeps the automatic transmission working and helps it shift properly, especially when the truck is working hard.

Term

overdrive

Overdrive is an extra gear that helps the engine spin slower when you’re driving steadily. If you lose overdrive, the transmission may not be getting the right fluid pressure, so it can’t use the higher gear.

Term

fluid

Transmission fluid is what the transmission uses to shift. If the fluid level gets low, the transmission may not have enough pressure to keep the gears engaged.

Term

transmission hose

A transmission hose is a rubber line that carries transmission fluid. If it fails on the road, you can lose fluid and the truck may not shift properly, so having a way to repair it can help you get moving again.

Term

factory cooler line steel

The transmission cooler line is the line that sends transmission fluid to a cooler to keep it from overheating. If the line rubs through, it can start leaking and you can lose transmission function.

Term

compression fittings

Compression fittings are quick connectors that clamp onto a metal line to make it leak-free. They’re handy when you need to fix a line fast and get back on the road.

Term

transmission's blown

“Transmission’s blown” usually means the transmission is badly damaged and won’t work right. The speaker is saying some people jump to that conclusion, even when a simpler fix might work.

Term

tow truck

A tow truck is what you use to pull a vehicle that can’t drive itself. Here, it’s part of the backup plan when the truck starts making scary noises.

Concept

coast off

“Coast off” means you let the vehicle roll to move it without using the engine much. It can help you get to a safer spot, but it doesn’t solve what’s wrong.

Ford power stroke
Car

Ford power stroke

Power Stroke is Ford’s diesel engine used in certain Ford trucks. Here, it’s the truck the mechanic used to help tow and rescue the speaker’s vehicles.

Part

push rods

Push rods are internal engine parts that help move motion from the camshaft to the valves. If a push rod breaks, the engine can start making loud, bad-sounding noises and may run poorly.

Term

hammering

“Hammering” means a loud, harsh knocking noise from the engine. In this case, it’s caused by a broken internal part (a push rod) in one cylinder.

Concept

broken push rod not bent

They’re saying the push rod snapped cleanly instead of slowly bending. That usually means something caused a sudden break, which can help figure out why it failed.

Term

heat treated

Heat treating is how manufacturers “tune” the metal so it can handle stress without failing. If it’s done wrong, parts can crack sooner than they should.

Term

alternator

The alternator is what keeps your car’s battery charged while you drive. If it stops working, the battery can only run the car for a little while, and then the car starts acting like it’s dying.

Concept

roadside repairs

Roadside repairs are what you deal with when the car breaks down and you’re not near a mechanic. The point here is that alternators fail often enough that it keeps happening to them.

Ford Excursion
Car

Ford Excursion

The Ford Excursion is a big SUV that’s built like a truck, so it can tow and carry a lot. The podcast mentions it in connection with an alternator issue, which is part of the car’s electrical charging system. If the alternator isn’t working right, the battery can drain and the car may act up.

Term

battery power

“Battery power” here refers to running the vehicle’s electrical systems using stored energy in the battery rather than charging them through the alternator. This is why a failing alternator can feel intermittent—everything may work until the battery voltage drops too low.

Term

ECM

The ECM is the engine’s computer. It tells the engine what to do, and if it gets damaged in a crash or failure, the engine may not run correctly or at all.

Part

cam

The camshaft tells the engine when to open and close the valves. If it breaks, the engine timing goes wrong and the engine can be badly damaged.

Part

water pump

The water pump moves coolant to keep the engine from overheating. If it fails badly, the engine can overheat fast and get damaged.

Part

oil pump

The oil pump sends oil through the engine to keep parts lubricated. If it fails, the engine may not get oil pressure and can be destroyed quickly.

Part

water neck

The water neck is part of the coolant plumbing. If it cracks or splits, coolant can leak out and the engine can overheat.

Part

timing case

The timing case is the cover that protects the parts that keep the engine’s timing in sync. If it breaks, those parts can get damaged and the engine can fail badly.

Term

common rail

Common-rail is a modern way diesel engines deliver fuel. It uses a pressurized fuel system and needs more electrical power to control it, which is why charging issues can be more of a problem.

Term

injectors

Diesel injectors are the valves that spray pressurized fuel into the engine’s cylinders in precise timing and quantity. In a common-rail diesel, they depend on electrical power and control signals, so weak charging or low voltage can prevent the engine from running or from building proper fuel pressure.

Term

CP three

CP3 is the name people use for the diesel’s high-pressure fuel pump. It’s responsible for building the pressure the engine needs, so if the truck’s electrical system isn’t supplying enough voltage, the fuel system can’t work correctly.

Term

cruise control

Cruise control lets you set a speed and the truck keeps it for you. It’s useful on long drives because you don’t have to keep your foot on the gas.

Term

low pressure oil light

That warning light means the engine isn’t getting enough oil pressure. Since oil is what lubricates the engine, you should take it seriously and check what’s wrong.

Term

oil pressure

Oil pressure tells you how well the engine is pumping oil around. If it gets too low, the engine parts don’t get lubricated and can wear out or get damaged fast.

Term

turbo drain bolts

The turbo needs oil to keep it lubricated. The turbo drain bolts hold the oil return path; if they loosen, oil can leak and the turbo may not get the right oil flow.

Term

neutral

Neutral is the gear position where the engine isn’t pushing the wheels. Mechanics use how the car sounds in neutral vs drive to narrow down where a problem is.

Term

torque convertibles

In an automatic transmission, a torque converter is the part that uses fluid to help the engine turn the wheels. It helps the car get moving smoothly, especially from a stop.

Part

billet flex plate

A flex plate is a metal link between the engine and the automatic transmission. A “billet” flex plate is made from a solid piece of metal, usually to handle more stress than the factory part.

Sonoma Gmc S15
Car

Sonoma Gmc S15

The Sonoma is a pickup truck model. The podcast is describing a situation where the truck seems to lose oil, so the owner ends up carrying extra oil. That usually means there’s an oil leak or the engine uses oil faster than normal.

Term

low pressure issue

A low oil pressure problem means the engine isn’t pumping oil with enough pressure. When it gets hot, the host’s engine would trigger the oil warning light.

Term

interstage boost pressure gauge

This is a gauge that measures how much boost pressure is present in the turbo system. It helps you see if the turbo is performing the way you expect.

Term

AFC live line

AFC relates to controlling how the engine meters fuel based on airflow. The host is describing an in-cab setup to monitor/adjust engine behavior.

Term

oil drain on the turbo

Turbos use engine oil to keep them lubricated. They also have a return path to send that oil back—if that return gets blocked, oil can build up and start leaking out badly.

Concept

cooling-system overheating

Overheating means the engine is getting too hot because the cooling system isn’t working properly. If you don’t address the coolant problem, it can lead to serious engine damage.

Term

antifreeze

Antifreeze is a coolant mix that helps prevent the cooling system from freezing in cold weather and from boiling over when it’s hot. Plain water can work in a pinch, but it’s not ideal for long-term protection.

Term

thermostatic bypass

A thermostatic bypass is a temperature-controlled path for transmission fluid. It lets the fluid avoid the cooler when it’s too cold, and then it switches so the fluid goes through the cooler once it gets hot enough.

Term

transmission cooler

A transmission cooler is a heat exchanger that helps remove heat from automatic transmission fluid. By forcing fluid through the cooler once it reaches a certain temperature, it helps keep transmission fluid from overheating and degrading.

Term

pinch the top bypass line

They’re describing a workaround where you clamp off a hose that normally lets fluid skip the cooler. The goal is to force the transmission fluid to go through the cooler instead, especially if the temperature valve is stuck.

Part

tire plug kit

A tire plug kit is a set of tools and rubber plugs you use when your tire gets a puncture. You can plug the hole to keep air from leaking so you can drive to get it properly fixed.

Part

air compressor

An air compressor is what you use to put air back into a tire. Here, it’s the kind you can run from your truck’s power outlet so you can inflate the tire right away.

Term

cigarette lighter

A cigarette lighter is the old-style power outlet in a car. Today it usually means the 12-volt socket you can plug things into, like a tire inflator or phone charger.

Term

power port

A power port is the car’s outlet for plugging in accessories. In this context, it’s how the air compressor gets power so you can inflate a tire.

Dodge Charger
Car

Dodge Charger

The Dodge Charger is a car made for power and sporty driving. People often talk about it because it can be modified and because older ones are common. In the podcast, it’s mentioned as a vehicle someone used before.

Concept

boony kit

A “boony kit” is a nickname for a small set of handy tools you keep in your vehicle. The idea is to be prepared for simple roadside problems without needing to find help immediately.

Term

serpentine belt

The serpentine belt is a single belt that powers important stuff on the engine. If it comes off or breaks, the car can lose charging (alternator) and cooling (water pump), so it can overheat fast.

Term

tensioner

The tensioner is what keeps the belt tight. If the belt isn’t tight enough, it can slip or fall off when the engine is running.

Term

exhaust break

An exhaust brake helps slow the truck down by using the engine. It’s especially useful when towing, because it can take some work off the regular brakes.

Term

tows

Towing refers to pulling a trailer or another vehicle with a hitch-equipped vehicle. In the context of modified diesels, towing performance is often discussed in terms of how well the truck maintains speed and control under load.

Term

factory map sensor

A MAP sensor is a sensor that tells the engine computer how much pressure is in the intake. That helps the computer decide how much fuel to inject and how to manage boost. “Factory” means it’s the original sensor that came with the truck.

Term

boost gauge

A boost gauge shows how much pressure the turbo is making. If you don’t have one, you’re relying on other readings—like sensor data—to know what boost you’re actually running.

Term

40 psi

“psi” is a way to measure pressure. Here it’s talking about turbo boost pressure—how hard the turbo is pushing the engine.

Term

self-tappers

Self-tappers are screws that make their own threads when you drive them in. Here they’re used as a quick way to hold something tight near the turbo.

Term

turbo flange

A turbo flange is the metal “connector” where the turbo bolts to the pipe. If the sizes don’t match, exhaust can leak, so you need the right fit or a seal.

Term

JB Welding

JB Welding is a strong two-part glue/repair compound. Here it’s being used like a temporary seal to stop leaks around a turbo connection.

Term

fiberglass insulation

Fiberglass insulation is a heat-resistant material. In this story it’s used to help fill space and improve sealing near the turbo.

Concept

temporary field repair to get home

They’re talking about a quick, temporary fix you do just to make it to the next stop. It’s not meant to be a permanent solution—just enough to get home.

Term

spare tire

A spare tire is your backup tire if you get a flat. Before you leave, make sure it’s there and ready to use.

Term

battery terminals

Your battery has metal connection points. If they’re loose or corroded, the car may not start or may act weird, so it’s worth checking before a trip.

Term

low tire

A low tire is a tire with not enough air. It can make the ride worse and raise the risk of a flat, so checking pressure before driving helps.

Term

jack

A jack is what you use to lift the car when you need to change a tire. If you don’t have one, you can’t fix a flat yourself.

Term

splined lug

This is the special tool that fits your lug nuts. If your lug nuts are different from stock, you need the matching tool to take the wheel off.
