Technical Too Afraid to Ask
Term

tire inflation

"Tire inflation. That's number five out of eight. This one really knocks it out of the park. Under inflated tires increase rolling resistance."

Tire inflation means making sure your tires have the right amount of air in them. If they're not filled properly, it can make your car less safe and use more gas.

Term

rolling resistance

"Under inflated tires increase rolling resistance. That's friction and cause a decrease in fuel economy. I'm going to give you two statistics."

Rolling resistance is the difficulty your tires have when they roll on the ground. If it's high, your car uses more gas because the engine has to work harder.

Term

fuel economy

"...and cause a decrease in fuel economy. I'm going to give you two statistics."

Fuel economy is how far your car can go on a certain amount of gas. The better the fuel economy, the less gas you need to drive the same distance.

Term

natural leakage

"...it's a natural occurrence. It's not a leak that we can fix. It's what we call a natural leakage."

Natural leakage is when air slowly escapes from your tires just because of how they're made. It's normal and happens over time, especially when it's cold outside.

Term

tire pressure

"the winter months to stay on top of your tire pressures. But when you listen, when you get this next statistic on the fuel saving tips on tires being under inflated..."

Tire pressure is how much air is in your tires. If it's too low, it can make your car use more fuel and wear out the tires faster.

Term

friction

"When it comes to mechanicals and components on your vehicle, heat is the enemy. Friction is heat."

Friction is what happens when two things rub against each other. In cars, too much friction can cause parts to wear out faster and create heat.

Term

PSI

"For every one PSI of underinflation, you're losing 2% fuel"

PSI is a way to measure how much air is in your tires. It's important to keep it at the right level for safety and to save fuel.

Term

under-inflated tires

"...when the tires under inflated cuts into the sidewall of tire and chews it up..."

Under-inflated tires are tires that don't have enough air in them. They can cause your car to use more gas and can be dangerous if they blow out.

Part

tire sidewall

"...the inside of the tire on the sidewall because that's the part that take, cannot take a lot of heat..."

The sidewall is the side part of the tire that helps hold it together. If the tire doesn't have enough air, this part can get damaged and cause problems.

Term

oxygen sensor

"...the money light is on, it's an oxygen sensor or fuel cap. That's BS. You got to test."

An oxygen sensor checks how much oxygen is in the exhaust from the engine. It helps the car use fuel more efficiently and produce less pollution.

Term

fuel cap

"...the lights on, it's your fuel cap because that's what happened to me..."

The fuel cap is the part that closes your car's gas tank. If it's not sealed properly, it can cause warning lights to come on and let fuel vapors escape, which is bad for the environment.

Term

NOx emissions

"...Nox emissions. Nox emissions is the one that's not healthy. And that is unburnt fuel vapor..."

NOx emissions are bad gases that come from cars and trucks when they burn fuel. These gases can cause air pollution and health issues, making it important to reduce them.

Car

Jeep Wrangler

"...y 07 Toyota FJ Cruiser and also on the 97 Jeep TJ Wrangler Rescue that we rescued from the crusher. I had t..."
Car

Toyota Fj

"on my 07 Toyota FJ Cruiser and also on the 97 Jeep TJ Wrangler Rescue that we rescued from the crusher."

The Toyota FJ Cruiser is a rugged SUV that looks unique and is great for off-road driving, based on a classic model from the past.

Term

fuel-air mixture

"A worn oxygen sensor is unable to detect and adjust the fuel-air mixture correctly..."

The fuel-air mixture is how much fuel and air are mixed together in the engine. Getting this right helps the car run well and use less gas.

Term

fuel trim

"...for fuel trim. And we'll talk about that when we talk about tune ups on modern day vehicles, high tech vehicles."

Fuel trim is how your car's computer adjusts the mix of air and fuel for the engine. If it's not right, your car might not run well or could pollute more.

Term

wheel alignment

"...two vehicles that we did a bunch of front end work on, are ready to hit the alignment rack or wheel alignment..."

Wheel alignment is making sure your car's wheels are pointing in the right direction. If they're off, your tires can wear out faster and your car might not drive straight.

Car

Hyundai Accent

"potholes out there the size of our moon size craters big enough to swallow a Hyundai Accent and fill the hole and smooth it off."

The Hyundai Accent is a small car that is inexpensive to buy and run. It's a good option for people who want a reliable vehicle without spending a lot of money.

Term

steering geometry

"they knock out the steering geometry. They do. Period. Again, bring me 10 cars at random from the local grocery store parking lot. Just go around and pick them and bring them to me."

Steering geometry is how the parts of a car's steering system are set up. If it's not right, it can make the car harder to control and cause uneven tire wear.

Term

tire wear

"Tire wear is an indicator of number one, under inflation, over inflation. Number two, steering suspension components that are worn out."

Tire wear is how much the rubber on your tires gets used up. If your tires wear unevenly, it can mean there are problems with how the car is set up or how the tires are inflated.

Term

suspension components

"Number two, steering suspension components that are worn out. Number three, you just find it impressive."

Suspension components are the parts that help a car's wheels move up and down smoothly. They make sure you have a comfortable ride and help the car handle well on the road.

Term

pushing

"...that means a vehicle's pushing. If you watch NASCAR or any auto racing, they have to make adjustments on the fly..."

'Pushing' happens when a car doesn't turn as much as the driver wants it to. Instead of going around a corner, it goes straight, which can be dangerous in racing.

Concept

NASCAR

"...If you watch NASCAR or any auto racing, they have to make adjustments on the fly. When they get a yellow caution, the car can come in and they can touch it..."

NASCAR is a type of car racing in the United States where cars race around a track, usually in circles. Drivers and teams have to make fast changes to their cars during the race to keep them competitive.

Term

blowout

"...and then they blow, then they have a blowout, then a caution comes out because the tires all over the track..."

A blowout is when a tire suddenly goes flat while driving, which can make it hard to control the car. It's dangerous, especially if you're going fast.

Term

suspension problems

"If they don't, you've got suspension problems in the rear."

Suspension problems are issues with the parts of a car that help it ride smoothly. If something is wrong, it can make the car drive badly and wear out the tires unevenly.

Term

miles per gallon (MPG)

"miles per gallon. Penalty is 1.5 MPG, miles per gallon. So if you've been, if you've stuck around..."

Miles per gallon (MPG) tells you how many miles a car can drive using one gallon of gas. The higher the number, the less gas the car uses, which saves you money.

Term

fuel saving tips

"you got four fuel saving tips. Now, in episode two, when you listen to this, that'll wrap you up and give you eight fuel saving tips."

Fuel saving tips are ways to help your car use less gas. This can include things like keeping your tires properly inflated or driving at a steady speed.

Term

checklist

"This is a checklist that is absolute freaking gold, my friends. It's gold. Why? Because get your miles per gallon up..."

A checklist is a list of things you need to do or check on your car. It helps make sure you don’t forget anything important when taking care of your vehicle.

Term

RPM

"remember tomorrow morning when you're out driving, look at the RPM gauge. So between 2,200 and 2,500 RPM, 2,200 is a sweet spot."

RPM means how many times the engine's crankshaft makes a full rotation in one minute. If the number is too high, it can use more gas and wear out the engine faster.

Term

burnout

"...just like a fellow watching them do a burnout. I love it, a big smoky burnout. My father would say, there's someone got more money than brains..."

A burnout is when a car spins its wheels while staying in place, making lots of smoke. It's often done to show off or to make the tires stick better for racing.

Term

locking wheel nut

"...I used to have to go looking for the locking wheel nut dewy thingy to get the wheel nuts off..."

A locking wheel nut is a special nut that keeps your car's wheels from being stolen. You need a special key to take it off, which helps protect your wheels.
