Practical Automotive Advice to Save Money on Car Repairs Were Under The Hood
Concept

replica OEM wheels

“Replica OEM wheels” are wheels made by other companies that look like the original factory wheels. They usually cost less, but you still want to make sure they fit your car correctly.

Term

crank

To “crank” means the starter spins the engine. If the lights work but it won’t crank, the problem is often in the start/ignition path.

Concept

dash lights on but no start

If the dashboard lights come on but the car won’t start, the battery is probably okay, but the “start” signal isn’t getting through. That can be caused by the ignition switch or lock cylinder.

Term

ignition switch

The ignition switch is what tells the car to start when you turn the key. If it’s worn out, the lights may come on but the engine won’t crank.

Term

relays

A relay is like an electrical switch that controls power to another component. If it’s going bad, the car may act up intermittently. That’s why it comes up in starting problems.

Term

fuses

Fuses protect electrical circuits by breaking the connection when current is too high. A blown or failing fuse can cause certain functions to stop working, sometimes intermittently if there’s a loose fuse or related issue. The speaker mentions checking fuses after noticing weird starting behavior.

Term

voltmeter

A voltmeter is a tool that checks if electricity is reaching a part of the car. Mechanics use it to see whether a switch or wire is getting power.

Term

boost pressure

“Boost pressure” is the extra air pressure created by a turbocharger or supercharger. If throttle control and fueling don’t coordinate properly, boost behavior can change, which can contribute to smoke and poor performance.

Term

Eco Diesel

Eco Diesel is a diesel engine option. The host is saying that on this diesel, removing certain parts can be risky if corrosion has built up.

Term

torque wrench

A “torque wrench” is a tool that tightens fasteners to a specific torque value. The host suggests using one (and setting it conservatively) to avoid over-torquing and breaking glow plugs during removal.

Term

glow plugs

Glow plugs help a diesel start by warming things up. If they get stuck, removing them can be a big job.

Concept

under warranty

Under warranty means the car’s manufacturer will pay for certain repairs. They’re saying the dealership may only do the job if the warranty covers it.

Jeep Grand Cherokee

The Jeep Grand Cherokee is a common SUV. The speaker is saying they’ve seen them go to very high mileage, so it’s not always as bad as people fear.

Term

OEM replica wheels

These are replacement wheels that copy the look of the factory wheels. They can cost less, but you still need to make sure they fit your car correctly.

Company

road ready wheels dot com

They’re talking about a wheel seller called Road Ready Wheels. The point is you might be able to buy replacement wheels for less than you’d pay elsewhere.

Company

Berkeley one classics

They’re talking about an insurance company for classic or special vehicles. The goal is to get the right coverage so you’re protected without paying for too much or too little.

Term

snow tires

Snow tires are tires made for winter weather. They grip better on snow and ice than regular tires, especially when it’s cold.

Concept

direct fit

Direct fit means the wheels are made to bolt on properly. You shouldn’t need extra parts or modifications to make them work.

Term

33s

“33s” means the car has big tires. Big tires can help off-road, but they can also make the vehicle feel slower.

Term

jacked up

“Jacked up” means the car sits higher than stock, usually for off-roading. It can look cool and handle rough ground better, but it can also affect how it drives.

Term

misfire

A misfire means the engine isn’t burning fuel correctly in one or more cylinders. The car may shake, hesitate, or “chug,” and it can happen sometimes rather than all the time.

Term

OEM spark plug

OEM spark plugs are the same type (or very close) to what the car was built with. They’re usually a safer choice than cheap alternatives.

Brand

Motorcraft

Motorcraft is Ford’s parts brand. The idea here is to use a reputable, factory-style plug instead of a bargain one.

Term

porous block

A porous block means the engine block has a flaw that can let coolant leak where it shouldn’t. That can cause problems like coolant getting into the cylinders.

Term

K-Seal

K-Seal is a product you add to the coolant to try to stop small leaks. It won’t work for big leaks or serious internal coolant problems.

Concept

fix what you got

Instead of giving up on the car, you repair the problem. They’re saying it’s often smarter financially than selling it for a small amount and buying something else.

Concept

drive it gently

“Drive it gently” means don’t accelerate hard or push the car. It can reduce strain on a transmission that’s acting up.

Term

low oil pressure warning

This warning means the engine may not be getting enough oil pressure. If it’s real (not just a sensor glitch), the engine can wear out quickly, so it’s important to check it right away.

Term

changed the oil

They already changed the oil, which is usually the first thing you do when you see an oil problem. If the warning still shows up after the change, it usually means something else is wrong.

Concept

used engines

A used engine is an engine taken from another vehicle (usually a wrecked one) and installed in your car. It can be a cheaper way to fix a major engine problem than replacing everything new.

Term

wheelstander

A wheelstander is a car that lifts its front wheels during hard acceleration. It’s usually done on purpose for drag racing shows because it looks dramatic and requires tuning to do safely.
