As a car owner it is your responsibility to ensure that your car is maintained and road legal. There are many things that can go wrong with a car from time to time and one of the more costly jobs is often involving the cam belt.
A cam belt is the belt that drives the cam which synchronises the rotation of the crankshaft and the camshaft so that the engine’s valves open and close at the proper times during each cylinder’s intake and exhaust strokes.
Most cars have a rubber belt but some are fitted with a chain belt which means they are much less likely to break. The rubber cam belts will often need replacing at certain intervals and may need tensioning in-between changes. If this is not done you run the risk of the belt snapping or loosening too much and causing internal damage to the engine, which can often be enough damage to make the car a write off and beyond economical repair.
Some cars need the cam belt changing approximately every sixty thousand miles or so where as other may only need it doing every one hundred and twenty thousand.
Always get the cam belt changed as soon as possible on a second hand car unless you can be certain it has been done recently.
