Is It Time to Replace Your Timing Belt?

A timing belt is one way to control the opening and closing of engine valves by connecting the crankshaft to the camshaft of the vehicle. Generally, the timing belt does this by having teeth that lock into the teeth of the two gears for the crankshaft and camshaft.

The timing belt assumes the role of keeping the engine "in time" mechanically. The top and bottom half of a four-stroke, internal combustion engine must be absolutely in sync with its bottom half to finish a four-stroke cycle of intake, compression, power, and exhaust. The belt interacts with various cogs that connect to the crankshaft or bottom half of the engine and the camshaft or top half of engine. The timing belt achieves absolute agreement by synchronizing each movement of the top and bottom halves of your engine to effect the four-stroke cycle that generates power in your engine.

Because the belt is made from rubber, it is prone to stretching and breaking due to too much heat. As heat penetrates to the belt, it stretches and deteriorates causing the teeth of the belt to wear out. If there are no teeth to secure the belt, a collision of car parts is made possible. In order to prevent this from happening, it is necessary to periodically check the timing belt. If necessary, replace the timing belt.

A timing belt replacement may only take a few minutes but it may take you longer to scour through the hordes of wires and tubes before getting to the belt. You need to be very careful when changing the belt so it may be best to seek the help of a mechanic to ensure you do not mess up the car mechanisms. If the belt is loose, a tooth or even more may be skipped on the cam gear. This would reduce the engine performance of your Timing Belt Company.
