Timing Belt & Cambelts
A number of vehicles are fitted with timing belts (cambelts) as opposed to timing chains. A timing belt is an integral part of the internal combustion engine that synchronises the rotation of the crankshaft and camshaft. It is critical in preventing the pistons from striking valves. The belt is made from rubber which perishes and weakens over time. As such manufacturers recommend regular replacement.
Replacement intervals vary from 4-10 years and are also mileage dependent.
Timing belt failure is much more costly and inconvenient to the motorist than timing belt replacement.
