Suspension is all about giving your car a smooth ride. Can you imagine what it must have felt like for those first motoring pioneers as they bumped and rocked their way over every single shingle and nook in the road? Nowadays, we barely notice a crevice or the smaller pot holes thanks to the high design quality and engineering of our shocks and springs.

However, suspension is about more than keeping you from being jostled and pushed around in the driving seat. Did you know that this system also helps keep your wheels in contact with the asphalt, improving traction? Which can result in an increase of stopping distances by up to 20% if the system is worn or broken.

Look down the side of any tyre in the UK, and you’ll see a number of markings. Have you ever wondered what these actually mean? They’re put there by manufacturers to display different properties of the tyre – helping you ensure that the right one is on your vehicle.

Your car needs to combust petrol. And as every GCSE science student will tell you, this needs three things. Fuel, an ignition source and air.

In engines, this is supplied by the petrol, diesel or other fuel source, the spark plugs, and the air is drawn through the air filter, ensuring that dirt and muck doesn’t enter into the piston chambers. Of course – all that filth ends up caught in the air filter, reducing its effectiveness.

Replacing your cam belt is a vital part of your car’s maintenance schedule. Leave it to break, and you could cause untold damage to the rest of the car. If it fails, then the knock on effects can cause the engine’s pistons and valves to collide. Your car will break down, and it’s likely that the repair bill will be very hefty.

Yes, replacing the cam belt comes in at a significant cost. Which is why people might choose to ignore the warning signs. Remember however, that a written off engine is far more problematic.

Your fuel injectors are a vital part of the engine. As part of the main combustion system, they deliver fuel into the pistons, ensuring there’s enough fuel to drive your vehicle forward as you depress the accelerator. `

To keep the injectors in tip top condition they have to be cleaned from time to time. You might even find that with some complaints such as lit check engine lights and maintenance problems can actually be solved by unclogging your injectors before you embark on a costly course of replacement fuel injector. This bodes the question – what’s the best way to get them clean?

Your head gasket is a vital part of the engine. If it’s not working as the manufacturer intended then this can lead to bigger problems. You’ll find this critical seal between the engine block and the cylinder heads. It should be typically made of steel or copper, although some manufacturers use graphite and there are even asbestos gaskets in older cars.

The gasket helps ensure that the engine remains fully pressurised during the combustion process. Remember that the dynamic release of energy when fuel is ignited drives the pistons – so any drop in pressure means a drop in power. Oil and coolant are also supplied to the engine through the gasket, which means that problems with the part could lead to cross contamination between the two fluids – a problematic scenario for any engine.

Wheel bearings on older cars used to make a load of noise when they started having problems. These searing sonics would alert you to problems with the part and you could have them looked at before they became a major issue. Now, with all the soundproofing on the modern motor, it can be tough to distinguish bearing problems from tyre noise. However, if there’s a rumbling or grinding, accompanied by wobbling steering or uneven wear on your tyres – then wheel bearings could be to blame. In this article we go through some of the main danger signs.

The mass air flow sensor (MAF) is a critical component in your car’s fuel injection system. It sits nicely between the air filter and the intake manifold, carefully measuring the amount of air that’s being drawn into the engine to drive the combustion. The sensor sends the information to the Engine Control Unit (ECU), which in turn delivers the correct amount of fuel to the engine. As the sensor picks up different information about air density, temperature and other variables, it ensures that the engine functions at the most efficient level.

Your turbocharger is an important part of the engine, helping you accelerate faster and get to top speeds in important situations. It gives you that thrust when you want to overtake on the motorway, quickly and safely. On some cars you can even hear a satisfying rush as the turbo kicks in, forcing air into the engine. However, if your turbo stops working properly, your engine may become inefficient and could suffer from poor performance. What are some of the signs that your turbo is failing?
