What does the Timing Belt Do?
The timing belt does the same job as a chain – it links gears together to transfer movement from one to others.
The belt has teeth that mesh into a gear on the engine crankshaft to drive the camshaft which works the valves, in a lot of engines the timing belt also drives the oil pump & the water pump.
The timing belt is not the belt you can see when you look at your engine.
The belt you can see normally drives the alternator, air conditioning and the power steering. The timing belt is hidden behind the plastic covers.

Why does the Timing Belt need to be replaced?
The timing belt does carry a very high load, coping with high temperature & speed & may also have to cope with some oil contamination.
The timing belt is made from a special type of rubber compound, reinforced with fibre threads. The rubber will eventually wear out or in time perish.
If the timing belt slips or fails the valves will not open & close at the correct position (or time) to be in line with the crankshaft position.
In most engines this will cause the pistons to crash into the valves. When this happens the repairs can be very expensive and your car could be out of action for several days.
When should the Timing Belt be replaced?
