What is a Timing Belt / Cam Belt?
The job of the timing belt / cambelt is to turn the camshaft(s) at exactly 1/2 the speed of the crankshaft while maintaining a precise alignment. This means that the crankshaft will make two revolutions for every revolution of the camshaft. Engines will have at least one camshaft, or as many as four camshafts in some of the V-type engines. The camshaft causes the intake and exhaust valves to open and close in time with the pistons which move up and down in the cylinders. The valves must open and close at exactly the right time in relationship to the piston movement in order for the engine to run properly. Timing belts / Cambelts have a limited life span. Car makers use these belts instead of more durable chains because chains are noisier and cost more to manufacture. Your vehicle owner’s manual will recommend at what mileage the timing belt must be replaced. My car smalls like Rotten Eggs!
