The original quality timing cover for CHANGAN is a common component in internal combustion engines that protect timing gears, timing chains or belts, and other small parts. In applications where a timing chain is used, the original quality timing cover is usually at the front of the sealed cylinder block, and engines with timing belts usually have some timing cover-related parts. These covers can be made of metal or plastic and can consist of several different parts.

Car and truck engines use several types of gaskets, including sealing the original quality timing cover for CHANGAN. Timing chain covers are usually designed to seal the front end of the engine block. This is usually so that the timing gears and chain can be lubricated with oil. These original quality timing covers are usually sealed to the cylinder block with a timing cover gasket, the main purpose of which is to prevent engine oil from leaking out and malfunctioning.
In auto parts, an engine with a timing chain usually has a metal cover, while an engine with a timing belt may have a cover made of a variety of different materials. In the case of a sealed engine, the function of the original quality timing cover for CHANGAN is primarily to protect the belt from damage and prevent contamination from entering the belt.
