What is a cambelt?

Timing belt is a toothed belt that connects the engine crankshaft to the camshaft or camshafts. The timing belt is needed to synchronize the camshaft to the crankshaft position, so the valves will open and close at the proper time in the relation to the position of the pistons.

Why is it important to replace it?

The timing belt serves a very important part when it comes to making your engine run. Namely, the timing belt is the belt that controls the camshafts in your engine and keeps the entire operation running smoothly. Due to the belt being made of rubber, it ages and with constant use is under stress.

Typical causes of timing belt failure vary from old age to contamination by an adjacent oil or water leak. Bad fitting, such as either under- or over-tightening a new belt, can cause it to fail prematurely, as can failure of neighboring components. Timing belts do not tend to snap – it is more common for the belt’s teeth to experience stress cracks at their roots, prior to becoming detached. In some cases, idlers and tensioners can seize, throwing the timing belt from its pulleys and causing extensive damage to the engine, with bent valves and even holed pistons resulting. All of which will lead to expensive repair bills.


Many engines also utilise the timing belt to drive the water pump, which can also seize with the same consequences as failed tensioners, so you should not think that your garage is profiteering by suggesting that the water pump needs to be replaced as well. We also check the strength of antifreeze and condition of fan belts (alternator / power steering belt etc ) as in many instances these will need to be removed to get to the timing belt repair done.
