A cogged belt, usually of reinforced rubber, that drives the camshaft in an internal combustion engine
A timing belt, timing chain or cam belt is a part of an internal combustion engine that controls the timing of the engine's valves. Some engines use timing gears. The term "timing belt" is also used for the more general case of any flat belt with integral teeth. Such belts are used for power transmission or to interchange rotary motion and linear motion, where either high loads or maintaining a specific drive ratio are important. A common non-automotive application is in linear positioning systems. Such belts have also been used in efforts to make a cleaner, lower-maintenance bicycle transmission but have never become popular in this application
A crankshaft-driven "toothed" belt that drives an overhead camshaft or camshafts and, in some cars, a water pump The camshaft(s), in turn, via their cam lobes, open and close the cylinder head intake and exhaust valves This belt should be changed at the mileage interval recommended in your owner's manual or service manual, usually between 60,000 and 90,000 miles
