fan belt and timing belt

A CVT transmission belt, also known as a drive belt or variator belt, is a unique belt that plays a pivotal role in the operation of a continuously variable transmission. Unlike traditional automatic or manual transmissions that use fixed gear ratios, a CVT can adjust the ratio infinitely within a given range. This capability is primarily achieved through the movement and tension of the CVT belt, which connects two pulleys—the primary pulley and the secondary pulley.

3. Maintenance Schedule Most vehicle manufacturers provide a recommended maintenance schedule for timing belt replacement, commonly ranging from 60,000 to 100,000 miles. Ignoring these recommendations can lead to premature belt wear and the risks associated with a belt failure. Regular checks are imperative, and car owners should be aware of the signs that a timing belt may need attention, such as unusual engine noises, difficulty starting the engine, or visible cracks and wear on the belt itself.
