"Today's guest is a 2023 Subaru WRX. What was going on with this vehicle?"

The Subaru WRX is a sporty car that is great for driving fast and handling well on different types of roads. The 2023 version has updates that make it even better than before.

Term

B service

"So this vehicle came to our shop for a maintenance service. About 40 something thousand kilometers, 46,000 kilometers due for a B service."

A B service is a maintenance check for your car that looks at many important parts to make sure everything is working well. It's more detailed than just changing the oil.

Term

EV

"...or if it's an EV, there are things that are not applicable to obviously, you know, to inspect..."

EV means electric vehicle, which is a car that runs on electricity instead of gas. They are better for the environment and can save money on fuel.

Term

oil and filter change

"...there's an oil and filter change, unless it's an EV. Although there is oil on some of them..."

An oil and filter change is when you replace the old oil in the engine with new oil and also change the filter that keeps the oil clean. This helps the engine work better and last longer.

Term

clutch fluid

"The oil was replaced. The brake fluid and clutch fluid we replaced. It was due basically being two years old. And so we actually noted that it was recommended and we did actually replace that."

Clutch fluid helps the car's clutch work properly. It's important to change it regularly so that the clutch doesn't have problems when you shift gears.

Term

brake fluid

"change the clutch fluid? Well, the clutch fluid is like brake fluid. It basically absorbs water like brake fluid. It's a good idea to do at the same time as the brake fluid because it's absorbing the same moisture out of the air as brake fluid is."

Brake fluid is the liquid that helps your car's brakes work. When you press the brake pedal, this fluid moves to help stop the car.

Part

clutch master cylinder

"there's only two components really. There's a clutch master cylinder and clutch slave cylinder. There's no ABS system and really expensive bits and pieces."

The clutch master cylinder is a part that helps the clutch work when you press the pedal. It turns your foot's pressure into fluid pressure to make the clutch move.

Part

clutch slave cylinder

"there's only two components really. There's a clutch master cylinder and clutch slave cylinder. There's no ABS system and really expensive bits and pieces."

The clutch slave cylinder is another part that helps the clutch work. It takes the pressure from the master cylinder and moves the clutch to either let the engine connect or disconnect from the wheels.

Term

air filter

"...there's a photo of the dirty air filter. And then just looking at good items..."

An air filter keeps dirt out of your car's engine. If it's dirty, it can make your car run less efficiently and use more gas.

Term

wheel alignment

"...we don't actually do a full wheel alignment inspection, but just noting how the car drives..."

Wheel alignment makes sure your car's wheels are pointing in the right direction. If they're off, it can cause uneven tire wear and make your car harder to steer.

Term

tire rotation

"...we measure the tires and we rotate the tires during a B service if it's necessary and doable..."

Tire rotation means changing the position of your tires on your car. This helps them wear evenly and last longer.

Term

battery inspection

"...there's a numbers of what we actually get on the battery inspection, brakes are measured,..."

A battery inspection checks if your car's battery is working well. This is important because a good battery helps start your car and keeps the electrical systems running.

Term

brakes

"...brakes are measured, brakes are in good shape on this vehicle, pads, rotor, you know, everything's in good shape."

Brakes help your car slow down or stop when you press the pedal. It's important to check them regularly to make sure they work well and keep you safe.

Term

tire tread measurements

"...and then tire tread measurements. And we adjust the tire pressures to factory specs,..."

Tire tread measurements check how deep the grooves are on your tires. This is important because deeper grooves help your tires grip the road better, especially in wet conditions.

Term

factory specs

"...we adjust the tire pressures to factory specs, which is noted on there. So pretty simple."

Factory specs are the guidelines set by the car maker for how things should be on your car, like how much air should be in the tires. Following these helps keep your car running well.

Concept

vehicle inspection

"...literally check your car every year or every two years? You know, not going to the extreme of okay..."

A vehicle inspection is when a mechanic checks your car to make sure everything is working well and it's safe to drive. It's a good idea to do this regularly.

Term

check engine light

"...there's a check engine light and I put a piece of tape over it so I can ignore the damn thing. But how much of a difference does it actually make..."

The check engine light is a warning light on your dashboard that tells you something might be wrong with your car. It's important to pay attention to it and get it checked out.

Term

annual inspection

"...an annual inspection is really important because things start to wear..."

An annual inspection is like a yearly check-up for your car to make sure everything is working properly and it's safe to drive. It helps catch problems before they get worse.

Brand

Toyota

"...even if it's a Toyota, they have issues. There are manufacturing faults and stuff that you will pick up..."

Toyota is a car company famous for making cars that last a long time and don't break down often. Many people trust Toyota because their cars are usually reliable.

"...you check the service bulletins and repair bulletins for each vehicle when they're coming in for an inspection..."
