How Burnout Pushed Him to Start His Own Shop with Caleb Mac
Term

online training

Here, “online training” means learning courses you do on a computer or phone instead of in a classroom. The point is that the shop manager wasn’t making it easy to get started.

Term

lube tech

A “lube tech” is a shop role focused on lubrication and basic service work (often oil changes and routine inspections). In the episode, it’s used to debate what skill level that job should require—diagnosing issues versus only doing simple tasks.

Term

alternator

An alternator is what keeps the battery charged while the engine is running. If it’s not working, the battery can run out and the car may act like it’s losing power.

Term

battery

The battery is the part that provides electricity to start the vehicle and run electronics. If it’s weak or failing, the car may not start or may behave oddly.

Term

flush machine

A “flush machine” is a tool shop techs use to run fresh fluid through a car system. It’s often used for services like fluid exchanges rather than troubleshooting problems.

Car

1996 Polaris XLT 600

This is a Polaris snowmobile from 1996. “XLT 600” is the model name, and it tells you it’s a 600cc-class machine built for riding in snow.

Term

heat exhaustion

Heat exhaustion is when your body gets overwhelmed by hot conditions. It can make you feel lightheaded, nauseous, and like you have to stop what you’re doing.

Place

North Dakota

North Dakota is a U.S. state. The speaker mentions it because the incident happened while he was working there, about a few hours from home.

Concept

used car dealer

A used car dealer sells cars that aren’t new. Here, it’s relevant because the speaker describes learning on the job at a dealer and then getting thrown into bigger repairs than just basic maintenance.

Ford F150
Car

Ford F150

A Ford F-150 is a popular full-size pickup truck. Here, it matters because the person says they replaced the engine on one very early in their career, which is a big job compared with routine maintenance.

Term

engine

An engine replacement means swapping out the engine in the vehicle. It’s a big repair because the engine connects to a lot of other parts that have to be put back correctly.

Term

transmission

The transmission is what helps the car shift gears and send power to the wheels. If a shop is doing transmission repairs, it usually means the car isn’t shifting or moving correctly.

Term

electrical diag

Electrical diag means figuring out what’s wrong with the car’s electrical system. It can involve checking sensors and wiring, especially when the car’s computer is reporting errors.

Term

safetied

“Safetied” means the car has been checked and approved under the local safety rules. It’s basically the difference between “sell it as-is” and “sell it only if it passes the minimum safety checklist.”

Term

rocker panels

Rocker panels are the body panels running along the lower sides of a car, between the doors and the wheel wells. On modern unibody cars, they can be structural members that help carry loads, so rust or missing sections can make the car unsafe.

Term

full frame

A full frame means the car has a separate metal frame underneath that does most of the structural work. With that design, some outer body parts may not be considered as critical to safety as they are on unibody cars.

Term

unibody

A unibody is when the car’s body acts like the main structure, instead of having a separate frame underneath. That means damage to parts like the rocker panels can affect safety more than it would on older cars with a separate frame.

Concept

salvage yard

A salvage yard is where vehicles that are too damaged or unsafe to return to normal road use are taken for parts or disposal. The discussion links safety standards to keeping unsafe cars off the road and sending them to salvage instead.

Term

frame repair

Frame repair means fixing the car’s main structural support after it’s been bent, damaged, or badly corroded. Since that structure affects safety, it’s closely tied to whether the car can be approved for driving.

Cupra Born
Car

Cupra Born

The Cupra Born is a small electric car with a hatchback body. It runs on electricity from a battery instead of using gasoline. The podcast mentions it while talking about adjusting to life changes, which is often part of choosing a car.

'78 El Camino
Car

'78 El Camino

The El Camino is a Chevy that looks like a regular car, but it has a small truck bed. A ’78 is the version from the late 1970s, and people often fix them up as hobby projects.

Term

scan it for codes

“Scan it for codes” means plugging in a diagnostic computer to read error messages stored by the car. Those messages can tell the mechanic what part or system is having trouble.

Cadillac SRX
Car

Cadillac SRX

The Cadillac SRX is a mid-size luxury SUV made by Cadillac. Here it’s the specific vehicle they were stuck fixing, because the passenger seat wasn’t working.

Term

no power

In car troubleshooting, “no power” means the seat (or another part) isn’t getting electricity. If it only has a couple volts instead of the normal 12 volts, that usually points to an electrical problem like a fuse or wiring.

Term

road test

A road test is when you drive the car to see if the problem shows up the way the customer describes it. It helps you figure out what to check next.

Term

recertify

“Recertify” means you re-check the car to make sure it’s good again after work was done. The speaker is describing his process for verifying the fix.

Term

ignition misfire

A misfire means the engine doesn’t burn the fuel in one or more cylinders when it should. The car can feel shaky or weak, especially when you’re driving harder.

Term

5.4 Triton

The 5.4 Triton is a Ford V8 engine size (5.4 liters). In this story, it’s the engine that was causing the misfire problem.

Term

break off

“Break off” means something on the engine can snap or come apart. The speaker is saying that’s a known problem on that engine, but they don’t specify which part in this clip.

Term

plugs

Here, “plugs” means spark plugs. They’re the parts that make the spark that lights the fuel in a gas engine. The “headache” is that spark plugs can be hard to remove if they’re stuck or corroded.

Term

eight new coils

“Coils” are ignition parts that create the electricity for the spark plugs. If a coil is weak or failing, the cylinder can misfire. Replacing “eight coils” suggests the engine has eight cylinders that each need proper ignition.

Term

impact

They’re talking about using an impact tool to loosen the stuck parts. In this case, it helps get spark plugs out without as much struggle. That can prevent damage and save time.

Term

coil boots

Coil boots are protective rubber covers for the ignition coils. They help keep water and dirt away from the electrical connections. If they’re damaged, the engine can misfire.

Term

leak down test

A leak down test listens for where air escapes from a cylinder. If air leaks past rings, valves, or a head gasket, the engine won’t seal well and can misfire. It helps narrow down the exact mechanical cause.

Term

compression test

A compression test checks how well each cylinder is sealing. If a cylinder can’t build enough pressure, it can’t burn properly and may misfire. It’s a common way to find mechanical causes.

Term

Hemi

“Hemi” is a nickname for a certain Chrysler engine design. It has a combustion chamber shaped like a half-sphere, which helps the engine breathe and burn fuel efficiently. Here it’s just the type of engine they were working on.

Term

rock arm

A rock arm is part of the valve train that helps open the engine’s valves. If it can’t move, the valve may not open when it should. That can cause that cylinder to misfire.

'01 F-250
Car

'01 F-250

This is a 2001 Ford F-250, a big work truck. The point here is that the truck had serious problems with the frame and cooling, so it became a stressful job for the technician.

Term

frame rails

Frame rails are the big metal beams that form the truck’s skeleton. If they’re rotted, the truck can be unsafe, not just cosmetically damaged.

Part

water pump

The water pump moves coolant around the engine so it doesn’t overheat. Here it was leaking badly, which is a serious problem on a running truck.

Term

coil spring front end

A leaf-spring front end is a suspension design that uses long, layered springs. The host mentions it to describe where the frame problem is in relation to the truck’s front suspension.

Term

leaf spring shackle

The leaf spring shackle is a small mounting/pivot piece that helps the suspension move. The host mentions it to pinpoint where the damaged metal is on the truck.

Term

magnafluxed

Magnafluxing is a way to check metal for hidden cracks without cutting it apart. The host is saying that frame repairs should be inspected with proper testing, not just welded and assumed to be fine.

Term

safety inspection

A safety inspection is an official check intended to confirm a vehicle meets minimum safety requirements. The speaker references it to explain that repaired frames may need to pass scrutiny after welding so the vehicle is considered safe to operate.

Term

frame swap

A frame swap means replacing the truck or car’s main metal “skeleton” with another one. It’s a big job because so many parts bolt to the frame.

Term

Cab

The cab is the part of the truck where the driver and passengers sit. “Pulled a cab” means taking that section off to work on the truck underneath.

Term

box off a truck

On a pickup, the “box” usually means the bed where you haul things. Taking it off can be necessary to reach parts underneath for big repairs.

Chevrolet Silverado
Car

Chevrolet Silverado

A 2012 Chevrolet Silverado 1500 is a full-size pickup truck. Here, it’s the truck the speaker worked on for a “frame” job, which is a big, structural repair.

Term

box frame

A box frame is the truck’s main metal support structure made from enclosed steel “tubes.” The speaker is saying they always inspect a particular spot on that frame because that’s where problems can begin.

Chevrolet HHR
Car

Chevrolet HHR

The Chevy HHR is a small car with a retro look. The speaker mentions it because the customer noticed a strong fuel smell, which usually means something in the fuel system is leaking or has failed.

Term

fuel line rotted out

“Fuel line rotted out” means the metal tube that carries gas has rusted through. That can cause fuel to leak, which is why the car smells like fuel and it can become dangerous.

Term

pre-vent line kit

A “line kit” is a set of replacement parts meant to fix a specific part of a fuel line. The speaker is saying there’s a ready-made kit you can buy, but some people try to do it another way first.

Term

flare unions

Flare unions are metal connectors that join tubing by using a flared end. They help make a tight seal, which matters a lot for fuel lines so they don’t leak.

Term

3/8 copper plumbing

This means they used 3/8-inch copper tubing from a plumbing aisle for the repair. It’s a budget-friendly substitute approach the speaker says can work on older cars.

Part

ball joints

Ball joints are parts in the front suspension that help the wheels move and steer smoothly. If they get loose, the car can feel unstable and the alignment won’t stay correct.

Ford Expedition
Car

Ford Expedition

The Ford Expedition is a big SUV. Here they’re talking about a problem with the suspension—ball joints were loose—so the owner was planning to get an alignment.

Term

alignment

A wheel alignment adjusts the angles of the tires relative to the road so they track straight and wear evenly. If suspension components like ball joints are worn, alignment settings may not hold until the worn parts are replaced.

Toyota Tundra
Car

Toyota Tundra

The Toyota Tundra is a full-size pickup truck. In this story, the speaker did brake work on someone’s son’s Tundra.

Part

brakes

Brakes are what slow and stop the car. The speaker is saying he worked on the brakes on a Toyota Tundra.

Tesla Semi
Car

Tesla Semi

The Tesla Semi is a large electric truck used to move cargo. Instead of using gasoline or diesel, it runs on electricity stored in batteries. The podcast mentions it in the context of hauling a truckload of items to cities.

Part

brake master cylinder

The brake master cylinder is the main part that creates pressure in the brake fluid when you press the brake pedal. If it’s wrong or not working, the brakes may feel like they don’t work at all.

Term

bleeding the m- master cylinder out

Bleeding the brakes means getting air out of the brake fluid lines. Air makes the pedal feel soft and can reduce braking effectiveness.

Term

bleeding all four corners

That phrase means bleeding the brakes at every wheel. It helps make sure there’s no air in the brake lines so each wheel brakes properly.

Part

axle seal

An axle seal is a seal that keeps oil from leaking around the axle. If it leaks, oil can get onto brake parts and make the brakes less effective.

Part

right rear axle

The right rear axle is the part that sends power to the right rear wheel. If a seal leaks there, fluid can get onto braking parts and make the brakes work worse.

Term

gear oil

Gear oil is the oil used inside the axle/differential. If it leaks onto the brakes, it can get in the way of braking and make stopping less effective.

Term

proportioning valve

A proportioning valve is a brake part that controls how strongly the brakes apply to different wheels. It’s there to help the car stop straight and not skid or lock up the wrong tires.

Term

disc kit

A disc kit is an upgrade that swaps drum brakes for disc brakes. Because disc brakes work differently, the brake system may need to be set up correctly so the pedal feel and stopping performance are right.

Term

starter

The starter is the part that turns the engine over when you turn the key. If the starter is bad, the car may not start, even if everything else is fine.

Term

solenoid

The solenoid is like the starter’s electrical trigger. It helps connect the starter motor at the right moment so the engine can crank.

Term

bench test

Bench testing is when a mechanic checks a part outside the car to see if it works. It’s a quick way to confirm the starter is actually fixed before putting it back.

Jeep Cherokee
Car

Jeep Cherokee

A Jeep Cherokee is a common SUV. Here it’s just the car the host was driving while thinking about the cost of the repair job.

Term

key programmed

Key programming is when the car is set up to recognize your specific key. If you get a new key or replacement fob, the car usually has to be programmed so it will start.

Term

project cars

Project cars are vehicles bought with the expectation they’ll need significant work—often repairs, upgrades, or mechanical restoration—before they’re fully usable. In this conversation, the point is that without the shop’s help, the owner can’t keep buying cars that require major mechanical work to get running.

Term

vulcanizing machines

These are machines that heat tires so the rubber “cures” and sticks together the right way. Because they get extremely hot, they can accidentally start fires if the shop isn’t set up safely.

Term

overhead door

An overhead door is the big garage door that opens upward. In a repair shop, it matters because it determines how easily cars can enter and how the bays are laid out.

Term

portable scissor lifts

These are small lift platforms that raise a car using a folding “scissor” mechanism. They’re useful in tight shops because you can move them around instead of dedicating space to a permanent lift.

Term

7.3 Powerstroke

“7.3 Power Stroke” is a Ford diesel engine size (7.3 liters). Diesel engines are often chosen for towing because they make lots of pulling power at low speeds.

1997 F-350 regular cab
Car

1997 F-350 regular cab

This is a Ford F-350 pickup truck from 1997. It’s the kind of truck people use for towing and work because it’s built to handle heavy loads, and the speaker also mentions it has a diesel engine and a manual gearbox.

Term

five-speed

“Five speed” means the truck has five forward gears. That can help the driver pick the right gear for towing, like when you’re going uphill or slowing down.

Term

OBS Ford

“OBS” is short for “Old Body Style.” It’s a nickname people use for the older-looking generation of Ford pickups, and the speaker is saying they’ve always liked that classic look.

Company

Tech Assist

Tech Assist sounds like a help service or support tool the mechanic used while diagnosing a tough problem. It’s there to give guidance when you’re stuck.

Term

PCM

PCM means the car’s main computer for the engine and drivetrain. It tells the engine how to run, and if it’s bad, the vehicle can act weird or not start—so replacing and reprogramming it can fix the problem.

Term

program it

When you replace a car computer, it usually needs to be set up for that specific vehicle. Programming makes sure the new module “knows” the car and can control it properly.

Farmall M
Car

Farmall M

Farmall M is an old tractor model made by International Harvester. The host is saying his is a 1948 tractor that’s been parked for a long time and they’re planning to restore it.

Part

carburetor

A carburetor is the part that mixes fuel and air so an older engine can start and run. In the episode, they’re taking it off to clean it because the tractor has been sitting for years.

Term

pressure washed

Pressure washing is using high-pressure water to remove dirt and grime from a vehicle or engine components. In this context it’s part of the restoration workflow before disassembly and cleaning of the carburetor and intake area.

Term

carb cleaner

Carb cleaner is a solvent used to remove varnish, gum, and other deposits from carburetors and related passages. The host sprays it after pulling the intake, then reconnects the battery and tests for spark to see if the engine will fire.

Term

spark

Spark is the electrical “zap” that lights the fuel in the engine. The host checks for spark to make sure the ignition system is working before expecting the engine to run.

Farmall 806
Car

Farmall 806

Farmall 806 is an older tractor model made by International Harvester. The speaker bought it mainly to run a loader for moving snow, but it’s ended up doing a lot of other work too.

Term

LS swap

An LS swap is when people put a GM LS V8 into an older car or truck. It’s popular, but some enthusiasts dislike it because it can feel less “authentic” than keeping the original engine—though EFI makes it easier to drive.

Term

EFI

EFI means the engine uses electronics to spray fuel in the right amount. The big benefit is that it usually starts easier and runs more consistently than older carb setups.

Term

throttle body injector

Throttle body injection is a way to feed fuel using electronic injectors at the throttle. It’s a common upgrade path because it can make an older engine easier to start and drive than a carburetor.

Dodge Warlock
Car

Dodge Warlock

The Dodge Warlock is a pretty unusual classic Dodge pickup. The story here is about modernizing it with a newer Hemi engine so it’s easier to run than a carbureted setup.

Term

ECU

The ECU is the engine’s computer. When someone “flashes” it, they update the software so the engine runs properly with the parts that were swapped in.

Term

OBD2

OBD2 is the built-in computer diagnostic system in most modern cars and trucks. It lets a mechanic plug in a scanner to see error codes so problems are easier to find.

Part

axle shaft

The axle shaft is the part that spins to drive the wheels. If it has to come out, it usually means the repair needs access to the parts near the wheel.

Part

carrier bearing

A carrier bearing is a support bearing that helps the axle spin smoothly. If it seizes (basically locks up), the axle won’t come out easily and the repair becomes much harder.

'04 Toyota Camry
Car

'04 Toyota Camry

This is a 2004 Toyota Camry. On cars like this, parts that connect the axle can get stuck or seize, which makes repairs take way longer than expected.

Term

pressed-in wheel bearing

A pressed-in wheel bearing is a wheel bearing that’s forced into place. To replace it safely, you usually need a press, not just regular hand tools.
