There’s more to a car than just driving it. Sure, getting in the front seat and taking off seems to be easy as pie, but do you actually know how it all works?

If you do, you’re probably a car aficionado or a mechanic. For most other people, the knowledge is not generally filed away and easily accessible in your head, but thanks to the internet, it’s easy to find what you may not already know.

Knowing the parts of a car and how they work together is essential when trying to figure out any issues you may be having. It helps you troubleshoot where the cause might actually be.

The Most Important Parts of a Car

Take the time to get to know and understand your car. Learn how it works, and you’ll be better off in the long run.

1. The Battery

The battery is easily one of the most important parts of a car. It supplies the power that your car needs to start.

Don’t forget to turn the lights out if your car isn’t running because if you don’t, you’re liable to come back to a vehicle that has a dead battery.

2. Your Brakes

Did you know you have two separate braking systems in your car? One is the one you’re probably most familiar with – it is the one you use when you push the brake pedal in your car. These are the service brakes.

The other system is the emergency braking system. This one varies from vehicle to vehicle. Some are activated with a smaller pedal under your dash, near your service braking pedal. Others have a handle that you pull upward to engage the emergency brake. It is also widely known as a parking brake.

3. The Axle

Without the axle, your wheels wouldn’t turn. It’s the bar that runs under your vehicle and connects your wheels to the vehicle.

You’ve got two axles on your car. One is in the front, and one is in the rear. Axles are made of durable metals and so are more difficult to damage, which is good news for you.

That doesn’t mean that axles are invincible. To the contrary, they can rust and often do especially in places that deal with a lot of salt exposure. Rust can cause significant problems and can even cause your car to break down when it happens to an axle.

4. Fuel Injector

The fuel injector is a small car part that has a big job. It is the linking item that causes gas to go from your tank to your engine.

Having a working fuel injector can be the difference between paying more or less at the gas pump. The efficiency of fuel in your engine is increased by using a properly working fuel injector.

As a tip, you’ll want to clean and check it regularly to make sure it’s running correctly to increase its overall lifespan.

5. The Pistons

Depending on your vehicle, the number of pistons will vary. Some have four pistons, and some have six. Working pistons are critical to your engine’s performance as the pistons directly affect the how and why combustion works to make your engine go.

Pistons are responsible for rotating a certain number of times in a minute, also known as rotations per minute or RPMs. The faster the piston moves, the more RPMs your car’s engine handles.

In short, when your pistons are working at optimal performance, the car runs more smoothly, and fuel usage decreases.

6. The A/C Compressor

On a hot day where you walk outside and sweat through a shirt in less than the five seconds it takes to get from your house to your car, you want an air conditioner that works once you’re in your car.

That’s the job of your A/C compressor. It is responsible for ensuring that the air traveling through your car vents is either hot or cold.

When you have A/C problems, this is one of the first places to look. It could be a result of a coolant leak, a leaking seal, or other cracked and broken parts. If the A/C compressor doesn’t get lubricated properly, it will lead to a breakdown.

7. The Radiator

The radiator is one of the most important parts of a car because it is responsible for keeping your car from overheating.

It works by transferring heat away from the engine to keep your engine from going into a total breakdown. If the heat didn’t get transferred, you’d be looking at incredibly awful damage to your car.

The radiator kicks into gear when the engine reaches a temperature that is too high which then triggers a release of coolant and water. The liquid picks up the heat and sends it back to the radiator, therefore cooling the heat and keeping the temperature within safe ranges.
