Timing Belt

Certain engines with overhead camshafts have timing belts that have a limited life span. Car manufacturers use these belts instead of more durable chains because chains are noisier and cost more to manufacture. Your vehicle owner’s manual will recommend at what mileage the timing belt must be replaced as intervals range differently in all vehicles.

beltThe job of the timing belt is to turn the camshaft(s) at exactly 1/2 the speed of the crankshaft while maintaining a precise alignment. This means that the crankshaft will make two revolutions for every revolution of the camshaft. Engines will have at least one camshaft, or as many as four camshafts in some of the V-type engines. The camshaft causes the intake and exhaust valves to open and close in time with the pistons which move up and down in the cylinders. The valves must open and close at exactly the right time in relationship to the piston movement in order for the engine to run properly.

 

 

Brakes & Suspension

ghvgSometimes, your vehicle’s brakes will alert you when there’s trouble. Whistling noises, chirping sounds, and grinding are indications that maintenance is required. Vehicles often come equipped with a small thin piece of metal attached to the brake pad to act as a warning indicator when the pad material is getting low and the brake pads should be replaced.

This device makes a chirping noise on brake application, letting you know it is time to have your brakes serviced.

When your brake pads are fitted they will be extra sensitive so take extra care for the first few miles to keep a safe distance between you and the vehicle in front of you and to brake in plenty of time.

Your vehicle’s suspension system is effectively a complex series of components designed to work together to limit the vibrations and undulations from the road surface, providing a smooth, controlled and comfortable driving experience. Great brakes and tyres need to be in full contact with the road to work most effectively. In fact, at 30mph, worn shock absorbers can add up to 2 metres to your braking distance!

Clutch & Gearbox

The clutch plates inside your car are kept together by springs when you are driving. They separate when you press down on the pedal, to enable the gears within the car to be changed. Over time this regular, repetitive action eventually wears the clutch down, and it will need replacing.
