Dayco 95321 Engine Timing Belt Round Tooth

Dayco 95321 Engine Timing Belt, Round Tooth, is a synchronous timing belt engineered to maintain precise crankshaft-to-camshaft synchronization in OHC and DOHC gasoline engines. It is commonly installed in select passenger cars and light-duty vehicles, including various Volkswagen applications, to ensure accurate valve timing for engine performance, fuel efficiency, and emission control. The belt uses a high-modulus fiberglass tensile cord and a peroxide-cured rubber compound, featuring a wear-resistant round-tooth profile and a high-temperature, Teflon-coated tooth surface for durability over service intervals. In maintenance and repair scenarios, technicians replace this belt to restore proper valve timing, reduce engine wear, and ensure reliable operation.
