Often used in cars, trucks and SUVs, a timing belt is a key component of an engine. It connects the crankshaft and the camshaft, and helps to keep them in synchronicity. It is also responsible for synchronizing valves.
A timing belt is typically made from rubber and high tensile fibres. It is also known as a cambelt or a toothed belt.

There are many different kinds of belts. They may vary in the way they are designed, the material used, and the tooth profile they exhibit. They also vary in performance. The material of the belt can also have a significant impact on its lifespan.

Typically, timing belts made from rubber are notorious for breaking in hot engines. In addition, they degrade with contact with motor oil. For this reason, temperature resistant rubber materials are used to prolong the life of the belt.

Modern timing belts use a curved tooth profile to reduce friction and reduce weight. The belt's other main feature is its ability to transmit high torque. Its other novelty is its ability to help to ensure the proper opening of the intake and exhaust valves.

Timing belts may also be called cambelts or toothed belts. The belt is usually made from rubber or polymer and contains teeth on the inner side. These teeth can be contaminated by oil or coolant leaks. They should also be free of chunks and other signs of fraying.
In addition to timing belts, a vehicle's engine may also have a chain. The chain helps to carry large loads.
