Let’s take a look into your car engine room. When your engine start rotating, piston and valves inside the engine would have to work, open and close in specific timing. Those engine part attached to camshaft that revolving entirely depend on timing belt. The connections between the belt and camshaft make timing belt called as cambelt.
The timing belt itself is a thin but strong rubber belt that has teeth inside. These teeth has to fit to the slot in engine vehicle in order to make the engine work properly. These teeth also hold the belt at the right place. According to it’s manual, timing belt could use up to 100.000 km or a year. But moslty it just can work normally until 50.000 km. You should check this part more frequently from this point eventhough you feel nothing wrong with it. Changing the timing belt at this time also recomended.
Timing belt actually susceptible from external harm. Therefore you usually find the timing belt covered inside the engine room. Oil and dirt could ruin it’s work and could make it defective sooner. The size of this belt is depend on the size of engine. Bigger the engine, bigger the timing belt, and vise versa.
Before people using rubber timing belt for their engine, they using ferro chain. The durable of the ferro chain is more reliable than rubber timing belt, but it’s make hard noise that make the car owner feel uncomfortable. Than more people choosed the rubber than ferro timing belt.
