Timing Belt

Atiming belt is a toothed belt that connects the engine crankshaft to the camshaft or camshafts as you can see in the picture.
A timing belt synchronizes the camshaft to the crankshaft position, so the valves will open and close at the proper timing in relation to the position of the pistons. The camshaft rotates at exactly 1/2 speed of the crankshaft; meaning two revolutions of the crankshaft are equal to one revolution of the camshaft.
In some engines a timing belt can also drive additional components such as a water pump, balance shaft, intermediate shaft, injection pump and an oil pump. A balance shaft, an intermediate shaft and an injection pump must also be synchronised with a crankshaft.
To work properly atiming belt needs to be under certain tension that is controlled by atiming belt tensioner. Some older cars have an adjustable timing belt tensioner that must be re-adjusted if thetiming belt gets loose. Most of the newer cars have an automatic timing belt tensioner that doesn't need any adjustment. If the timing belt gets loose, it may skip a tooth and the proper timing will be lost.
When atiming belt is replaced, it's very important to set the timing properly. Before a a newtiming belt is installed, the crankshaft, the camshaft and other components synchronised with a crankshaft must be aligned in a certain way. A repair manual has proper instructions and a diagram with timing marks. Improperly set timing will cause a variety of problems such as lack of power, vibration, misfiring, etc.
