About this episode

Winter is here, and it's crucial to perform three essential checks on your vehicle: the exhaust system, battery, and timing belt. Niall Motormouth Jenkins shares insights on how to inspect these components to prevent costly repairs and ensure safety on the road. He emphasizes the importance of checking for exhaust leaks to avoid carbon monoxide issues, testing your battery to avoid unexpected failures, and understanding the risks associated with timing belts, especially in interference engines. Tune in for practical tips and a few laughs along the way!

Term

four-way flashers

"Here's an extra bonus motormouth tip. Put the four-way flashers on. Go to the back of the car. If the four-way flashers are working all the way around the car, that means your signals are all working."

Four-way flashers are the lights that blink on all sides of your car. You use them to warn other drivers when you're having trouble or need to stop unexpectedly.

Term

third brake light

"That means the brake lights are working at the back too except for the cyclops. The third eye, yeah, that's different. That's different."

The third brake light is an extra light on the back of your car that lights up when you press the brake pedal. It's usually located higher up, so it's easier for drivers behind you to see when you're stopping.

Term

power seat

"If it's a power seat or manual, just slip it forward and there you go. Brake lights are on."

A power seat is a car seat that you can move around using buttons instead of pulling on a lever. This makes it easier to find a comfortable position when you're driving.

Term

circle check

"What's the big deal about the walk around? You know what? Truck drivers, bus drivers, coach drivers, they all do their walk. They're circle check and we should do a circle check as well."

A circle check is when drivers walk around their vehicle to make sure everything is okay before they drive. They look at things like the lights and tires to catch any problems early.

Part

tire

"I'm looking at the tires, see if there's anything stuck in the tread that doesn't belong there."

A tire is the round rubber part of a car that touches the road. It's important to check them for any damage or things stuck in them to keep the car safe to drive.

Part

plug patch combo

"We were able to fix it with a plug patch combo but a spoon jammed in the tire and it was in and it was folded over."

A plug patch combo is a way to fix a hole in a tire. It uses a rubber plug to fill the hole and a patch on the inside to keep air from leaking out.

Company

"Thanks to Earl and Louise Grant at City Auto Sales and Leasing in Toronto. They're GTA's premier pre-owned auto store for well over 25 years now."

City Auto Sales and Leasing is a car dealership in Toronto that sells used cars. They focus on providing good quality vehicles and helping customers with financing options.

Company

Rainbow Motors and Garage

"...Rita and Ramiz, Shenouda, the owners at Rainbow Motors and Garage in Scarborough. You have a small car lot"

Car

Toyota Fj Cruisers

"...our old seven FJ cruisers got another exhaust leak,..."

The Toyota FJ Cruiser is a tough SUV that looks a bit like classic Land Cruisers. It's great for off-roading and has a unique style that many people love.

Part

exhaust system

"...exhaust system inspection, yep I got a leaker,..."

The exhaust system helps get rid of the gases that come from the engine. It also helps make the car quieter and cleaner for the environment.

Term

oxygen sensors

"...you got to open exhaust somewhere that throws off your oxygen sensors and what that means..."

Oxygen sensors check how much oxygen is in the car's exhaust. This helps the engine run better and keeps emissions low, which is good for the environment.

Term

carbon monoxide

"...the second thing is carbon monoxide doesn't smell taste or you can't even see it but in the winter it sits heavy underneath your vehicle, so if you're sitting there idling for way too long..."

Carbon monoxide is a dangerous gas that you can't see or smell. It can build up in your car if it's running for a long time without moving, which can be very harmful.

Term

battery testing

"...we need to be prepared and if we test the battery and and it's on the low side of the scale..."

Battery testing is when you check how well a car's battery is working. This helps make sure the car will start and run properly, especially in cold weather.

Term

booster cables

"...I got booster cables I thought well just check see if uh if uh CJ's in town...he goes yeah I gotta set two so we're good to go..."

Booster cables are long wires that help start a car with a dead battery by connecting it to another car's working battery. They transfer power from one battery to the other.

Term

standing voltage

"...the standing voltage on a battery is 12.6 to 13.4 volts and we want to see as close to 13.4 as possible..."

Standing voltage is the amount of electricity a battery has when it's not being used. It's a good way to check if the battery is still good.

Term

weak zone

"...if it drops into the weak zone which is around 11 to 10.6..."

The weak zone is when a battery's voltage is low, meaning it might not work well or could fail soon. It's a sign that you should replace it.

Term

timing belt

"...whether your engine under the hood has a timing belt show of hands I don't know it's another IDK moment that's what we say in the workshop IDK I don't know well you need to know because in the winter that's generally when they snap..."

A timing belt is a part of the engine that helps keep everything moving in sync. If it breaks, it can cause big problems, like damaging other parts of the engine.

Term

interference engine

"...if your engine is not is there's interference engine and non-interference and what does that mean okay try and make it simple..."

An interference engine is a type of engine where the moving parts can hit each other if something goes wrong, like if the timing belt breaks. This can lead to expensive repairs.

Term

engine damage

"...we're talking this may sound high tech but it just means major engine damage so if you go pile driving through slushy puddles..."

Engine damage means something is wrong with the engine that can make it not work properly. This can happen for many reasons and usually means it needs to be fixed or replaced, which can be very costly.
