Technical Too Afraid to Ask
Term

antifreeze

"You know, and find out, did your neighbor borrow some of your vehicle's antifreeze? Didn't leave a sticky note or anything?"

Antifreeze is a special liquid that helps keep your car's engine from getting too hot or too cold. It makes sure the engine runs smoothly in different weather conditions.

Term

closed system

"If you top it up, we have to ask ourselves, well, it's a closed system. Where did that antifreeze actually go to?"

A closed system means that the fluids in your car, like antifreeze, are supposed to stay inside and not leak out. If they do, it could mean there's a problem.

Term

TPMS

"Did you know? TPMS. Do you know what TPMS even stands for?"

TPMS is a system that checks if your car's tires have enough air. If the pressure is low, it lets you know so you can fill them up and stay safe while driving.

Brand

Lexus

"...ever since he got this Lexus SUV, he's like turned into a road animal."

Lexus is a brand that makes luxury cars, and it's part of Toyota, which is a well-known car company.

Term

maintaining his vehicle

"...and he's really good at maintaining his vehicle as well."

Maintaining a vehicle means taking care of it so it works well and lasts a long time. This includes things like changing the oil and checking the brakes.

Term

winter tires

"He says, Yeah, they just, I finally had my winter tire appointment and the tires are on."

Winter tires are special tires made for driving in cold weather, snow, and ice. They help your car grip the road better when it's cold outside.

Term

retorque

"I got to go back in a hundred K. They're going to retorque the wheels and say, Well, do you think we might want to get off at the next exit and take a look?"

Retorquing means tightening the bolts that hold the wheels on your car to make sure they are secure. This is done after putting on new tires.

Term

vibration

"Oh, no, I don't feel any vibration or anything."

Vibration in a car means that something might not be working right, like the tires or the wheels. If you feel it while driving, it's a good idea to check it out.

Term

PSI

"Let's get that right. A PSI inflation problem. It doesn't mean it's going up in inflation."

PSI is a way to measure how much air is in your tires. It tells you if your tires have enough air to drive safely.

Part

tire sensor

"it'll show you a picture of which tire sensor is picking up a reading that's showing that the tire inflation is low or it's below spec and they're not always completely accurate."

A tire sensor checks how much air is in your tires. If the air pressure is too low, it lets you know so you can fill them up and drive safely.

Part

Schrader valve

"The thingy, the Schrader valve that you put air into, that's part of the sensor but the sensor is on the inside, on the opposite side and they do tend to rot out."

A Schrader valve is the little piece on your tire where you put air in. It lets you inflate or deflate the tire as needed.

Term

corrosion

"but they still corrode. We're still seeing that."

Corrosion happens when metal gets damaged by things like moisture or salt, causing it to rust or break down. This can make parts like tire sensors stop working properly.

Term

tire pressure

"But anyways, when that TPMS light comes on, don't ignore it, you could have a tire that's cutting down..."

Tire pressure is how much air is in your tires. If the pressure is too low, it can make your car harder to control and can cause tires to wear out faster.

Term

steering tire

"you could lose control of the vehicle, especially if it's a steering tire."

The steering tire is the front tire that helps you turn your car. If it goes flat, it can make it very hard to drive safely.

Term

tire lifespan

"It causes loss of life of that tire, takes the lifespan of the tire away. Simple as that."

Tire lifespan is how long a tire lasts before it needs to be changed. It can be affected by how you drive and how well you take care of your tires.

Term

low pressure tire

"but because the vehicle's been driven on a very low pressure tire,"

A low pressure tire means it doesn't have enough air in it. Driving on it can cause problems like faster wear and even blowouts.

Term

car battery

"I'm testing car batteries. You'll want to watch that so that you can get a really good understanding of what makes up a car battery and why that's important to know..."

A car battery is what helps start your car and powers things like the lights and radio when the engine isn't running. It's important to know how it works to keep your car running smoothly.

Term

boost a battery

"...especially do not boost a freezing cold battery in the winter..."

Boosting a battery means using another battery to help start your car when the battery is dead. It's important to do it safely to avoid damage.

Term

voltage spikes

"...you risk number one, blowing a computer out of your car because of spiking, voltage spikes..."

Voltage spikes are quick bursts of electrical power that can happen when you start your car or when something goes wrong. They can hurt the car's electronics if they're too strong.

Term

battery explosion

"...the worst one, the battery can explode. So we don't want to see that happen because if you ever heard a cannon go off, that's exactly what it sounds like..."

A battery explosion happens when a battery gets too hot or is damaged, causing it to burst. This can be very dangerous and can hurt people nearby.

Term

H2SO4

"...the chemical composition is H2SO4. So when a battery is fully charged or in at least some state of charge, a fully charged battery is 12.6 to 13.4 volts. That's good..."

H2SO4 is sulfuric acid, a strong acid found in car batteries. It's dangerous and can harm you if it comes in contact with your skin or eyes.

Term

battery testing

"...go to our YouTube channel, Niall Motormouth Jenkins, and look in the library for battery testing, and watch it, and you'll see how I test batteries..."

Battery testing is how you check if a car's battery is working properly. It helps you find out if the battery needs to be charged or replaced.

Term

fuel economy

"...because we're running out of time here, I probably could have only just done three points, but we're giving you four. Fuel economy. Fuel economy for every one of us..."

Fuel economy is how well a car uses fuel. It tells you how far you can drive with a certain amount of gas, which helps you save money on fuel.

Term

electric vehicle

"Here's what you need to know about your electric vehicle. When it's freezing, stinking cold outside, the colder it gets, electrons slow down."

An electric vehicle is a type of car that runs on electricity instead of gas. It uses batteries to power an electric motor, which makes it different from regular cars that use fuel.

Term

fuel mileage

"...for all of us who are putting gasoline in our vehicles, in the wintertime, we get very poor fuel mileage. It drops..."

Fuel mileage is how far a car can go on a certain amount of fuel. In winter, cars often use more fuel because they need to keep the engine warm, which can make the mileage lower.

Term

air fuel mixture

"...because that engine is in the computers adjusting air fuel mixture to get the burn going. In other words, keep the fireplace burning hot inside that engine..."

The air fuel mixture is how much air and fuel the engine uses to run. If it's not balanced right, the engine won't work well, especially when it's cold outside.

Term

capillary action

"...put it in before you fill the tank so that the fuel creates what we call a capillary action like closing a dryer and it'll blend it. And if there is any water in the tank it'll dispel it..."

Capillary action is how liquids can move through tiny spaces, like when you soak a paper towel in water. In fuel systems, it helps mix things together and can push out water that might cause problems.

Part

fuel filter

"...from icing up your fuel filter because your fuel filter is a fuel purifier. It has several screens inside that filters out to .0001 microns..."

A fuel filter cleans the gasoline before it goes into the engine, making sure there are no dirt or tiny particles that could cause problems. It's like a strainer for your fuel.

Term

microns

"...that filters out to .0001 microns. Smaller than a grain of sand. Very teeny teeny weeny times teeny weeny..."

A micron is a tiny measurement used to describe really small things. For example, a grain of sand is much larger than a micron, which is why fuel filters can catch very small particles.
