Has it ever happened to you that you broke something in your car but didn’t know what it was called? It can be frustrating not being able to replace it. That’s why we’re here to help. Every driver should have a basic understanding of their vehicle, and that’s why we’ve put together a guide on the top 10 car parts you should know about. So, if something breaks, you’ll be able to find the replacement part on Perrys Car Parts. We have spare parts for over 200 car brands. Just input your registration number and you’ll find a wide range of products suitable for your vehicle.

1. Battery

Your car’s battery is crucial. Without it, your vehicle won’t start since it provides the necessary electricity for the engine. The battery is rechargeable and powers car accessories like radios and lights. Remember to turn off your lights and radio when the engine is off to prevent draining the battery. You’ll usually find the battery under the hood, and it’s a good idea to check it every six months to a year to see if the terminals need cleaning.

2. Axles

Axles are small bars that help you move, brake, and turn your wheels. They support the weight of the wheels and are an essential component of the steering system. While axles are usually sturdy, they can rust. If that happens, Perrys Car Parts can help you out. Just enter your registration number, and you’ll find specific axle beams for your car model.

3. Brakes

Taking care of your brakes is crucial since your car won’t be able to stop without them. Most modern vehicles have a hydraulic brake system, where the force on the brake pedal applies power to the brakes. If you hear a squeaky noise when pressing the brake pedal, it’s probably time to replace your brake pads and discs. Worn-out pads and discs can be dangerous, so it’s better to be safe than sorry.

4. Pistons

Pistons play a vital role in handling the gasoline explosions that power your car. They give power to the tires, making the car move. They work by handling the combustion process in the engine, where fuel and air mix and explode.

Cars and Their Powerful Pistons

Cars are equipped with an impressive arrangement of four to six pistons, taking on the shape of sturdy cylinders, which constantly reciprocate in an upward and downward motion. The mesmerizing efficiency of these pistons determines the number of revolutions your beloved car can conquer.

However, let us not overlook the crucial fact that excessive velocity can pose potential harm to these intricate pistons. This unwarranted celerity can lead to accelerated wear and tear, as well as unwelcome accumulation of grime. Fear not, for we offer a diverse range of impeccable piston essentials, tailored to suit your exquisite automobile model. Our selection encompasses an array of piston rings, seals, springs, sophisticated assays, and resilient head valves.


The radiator is like your car’s cooling superhero, tirelessly working to prevent overheating. It hangs out near the engine and relies on a generous supply of coolant to keep things cool. This magical fluid travels through your vehicle, attracting and whisking away all that pesky heat. As it reaches the radiator, a breeze passes through its fins, transforming the hot air into a cool, refreshing breeze. If your car starts to overheat, it’s probably time to give some love to your radiator. Luckily, we’ve got you covered with a wide range of engine cooling solutions, radiator fans, hoses, and sealing caps. No more hot-headed engines!

Shock Absorbers

Picture this: You’re cruising down a bumpy country road, but you’re feeling as smooth as silk. How? Shock absorbers, my friend! These unsung heroes keep your wheels glued to the road, absorbing all the jolts and vibrations along the way. Located beneath your car, they deserve some extra attention during your regular vehicle check-ups. You don’t want to mess with these suspension masters.

Air Filters

We’ve got not one, but two types of air filters to keep your car breathing easy. The first type ensures the air that enters your vehicle is as fresh as a daisy, constantly circulating clean air for your comfort. The second type is a special kind of clean freak, dedicated to purifying the air in your car’s engine. It’s super important to replace any worn-out or clogged filters to prevent debris and dirt from sneaking into your car chamber or, even worse, blocking that precious airflow. So let’s keep those filters clean and the air pristine. Your car will thank you!

Catalytic Converter

Behold, the car’s eco-warrior: the catalytic converter! It’s on a mission to filter out those harmful emissions, leaving only pure carbon dioxide and water in its wake. Talk about an environmental champion! Your car will turn from a noisy polluter into a planet-friendly vehicle. Now that’s something to feel good about.

Vehicle catalytic converters are incredibly durable and typically require no replacement throughout their lifespan. However, there are instances where they may experience blockages or damage, especially in older cars. Should you suspect a problem with your catalytic converter, indicated by a dashboard warning light, it is imperative to promptly replace it. It is important to note that driving without a catalytic converter is unlawful in the UK, so ensure immediate installation upon obtaining the replacement part.

The alternator is a crucial component that powers your car’s electrical system. It works by charging the battery while the car is running, converting mechanical energy into electrical energy. It’s important to note that leaving your radio or lights on when the car isn’t running can drain the battery. So, if you’re experiencing battery issues, it’s essential to check the alternator as well.
