Car detailing and cleaning is an important process for any car lover. We know how difficult it can be to keep your car looking as good as when you bought it, but occasionally, giving it some well-needed TLC can help keep it looking like you've just driven it out of the showroom.

The lightest scrape with a wall, lamppost or another car can leave a nasty scratch in your car's paintwork, and even the most careful drivers are likely to fall victim to a car scratch at some point. But you don't necessarily need to spend hundreds in a garage to get your pride and joy looking as good as new again.

Your car headlights are essential to your vehicle's lighting system. As well as illuminating the road ahead for you to see in poor conditions, they're also imperative for signalling to other road users where you are to them on dark roads.

The oil filter in your car is commonly underestimated. It's responsible for the healthy running of your car's engine. It cleans your engine oil by removing built-up contaminants, ensuring a clean engine over time.

Learning how to change the engine oil in your car without going to a mechanic can save you hundreds of pounds every year.

We rely on our cars for an awful lot, so there's nothing worse than when they show signs of being faulty or worn.

A dirty or failing air filter is one of the most common problems affecting your engine's performance. Whether you're a dab-hand with auto repairs or have a little basic knowledge, it can be too easy to forget about cleaning and checking the air filter

Whatever make or model your car is, it will have a catalytic converter that reduces the harmful emissions from the exhaust. This means your car is also at risk of catalytic converter theft

First things first, a cambelt is a timing belt. They're exactly the same component; we'll refer to both names in this guide. Whatever model of car you have, it will have a cambelt (timing belt), but you may not know what it does.

The ignition coil plays a crucial role in getting your car started and running the engine smoothly once you're on the road. Without it, your ignition system wouldn't be able to generate a spark, meaning the fuel in the engine combustion chamber wouldn't ignite. And you won't get very far if your car can't burn fuel.

The distributor – including the rotor arm and a distributor cap which covers it – is one of the many parts in the ignition system. So, naturally, you'll experience all kinds of problems when something is wrong with it – in fact, your car may not start at all.

The fuel filter performs the crucial job of preventing any pollutants from getting inside the engine, keeping your vehicle running smoothly and ensuring optimum fuel efficiency. However, it can only do this if it's kept in good condition

Spark plugs are a critical part of your internal combustion engine, so mechanics can charge a pretty penny for removing and refitting these.

It's happened to almost all drivers at some point: you hop in the car, turn the key or hit the ignition button, and your car won’t start. For reasons unknown, your car won't start, and you're not going anywhere. What's more, you can hardly pop along to the nearest garage to get your vehicle repaired when you can't even get it off the driveway.

Car thermostats play a vital role in regulating the temperature of your vehicle's engine. Without a fully functioning thermostat, the engine will be at risk of running too hot or cool, which can cause serious – and potentially expensive – problems.

Located at the front of your car, just behind the grill, is the car radiator. This radiator for your vehicle is a critical component in a vehicle's cooling system, keeping the engine running at the optimum temperature.

Flushing your car's radiator is essential for clearing accumulated dirt and debris in the cooling system. During this process, replacing the antifreeze in your radiator is crucial. This is important because antifreeze plays a key role in preventing your engine from

You probably don't think much about your wiper blades — until there's a problem with them, that is. These essential parts are responsible for clearing rain, sleet, or snow, as well as all the dust, mud, and bugs that can build up on the windscreen over time.

If you own a car or are thinking of owning one, you probably already know that you'll need an annual MOT. However, you might not know what this abbreviation stands for, or everything that is assessed when your car goes through the test.

Our cars go through a lot during the winter months. Ice-cold temperatures, heavy snow, and pothole-strewn roads can all wreak havoc with your vehicle — particularly the engine, battery, and tyres.

It’s easy to mix up coolant with antifreeze. With our guide, we’ll explain the differences between the two. Antifreeze is a chemical additive that lowers the freezing point and increases the fluid's boiling point in your car's coolant system.

Has your car fallen victim to a pothole or a rusty nail? While the last thing any motorist wants is a puncture or flat, there’s no need to panic: changing a tyre is actually quite straightforward as long as you have all the right equipment handy.

When was the last time you checked your tyre tread depth? If you haven’t checked them since your last service, you should set aside some time to test your tyres as soon as possible.

Do you find that your tyres wear out faster than they should do? Perhaps your car is burning through fuel more quickly than it once did, or maybe you’ve started to notice that the handling and braking feel less responsive.
