An integral part of the engine's timing system, the timing cam belt is powered by the crankshaft, connecting the crankshaft to the camshaft, and functions to drive various components that all work together to enable the car to move.
Situated in the engine compartment, the timing cam belt is a long piece of rubber which coils through a series of pulleys which contain bearings, usually operating with a spring mechanism. The pulleys function to enable the timing cam belt to smoothly spin around, allowing the belt to propel or drive various components in the engine compartment, such as the alternator, air pump and power steering pump. The pulley mechanism allows the timing cam belt to run along the inside of the tensioner, which enables it to apply tension to the belt as it spins around its path of pulleys and generates the mechanism and power needed to drive the components it serves. The camshaft receives power from the crankshaft via the timing cam belt. The timing cam belt works in conjunction with the camshaft pulley to make sure the camshaft is rotating in sync with the crankshaft. As the camshaft rotates via the belt and pulley system, it opens and closes the intake and exhaust valves. The timing cam belt controls how fast the camshaft rotates and enables the smooth rotation of the cylindrical camshaft ensuring the right amount of air and fuel is allowed to enter the engine at exactly the right time in order for combustion to occur in the cylinders.
If the timing cam belt comes loose it can deviate from its position. A sure sign of a loose timing cam belt is a nasty screeching noise. A slipped timing cam belt will lead to extremes of temperature as the belt struggles, eventually leading to a damaged belt. A slipped timing cam belt can also affect the proper performance of the components powered by the belt. Often the cause of a slipped fan belt is that the spring inside the tensioner has become worn and is unable to apply the right amount of tension to the timing cam belt. The cam belt can crack and warp and eventually break, due to the high temperatures and friction it has to withstand. When replacing this part, choosing to fit the timing cam belt will give you perfect compatibility with the make and model of your vehicle.
