The timing belt is situated in any vehicle so, that by removing, as well as installation, the central part of the timing belt cover and the damping engine device cannot be removed. This significantly simplifies maintenance. The cover was created to protect damageable parts of the timing mechanism from aggressive environmental influence: moisture, dust, dirt and other residues. It also involves physical protection of the timing belt from penetration of various impurities. Thus, the timing belt cover prevents premature wear out of the belt. And the replacement spacing of the timing belt was increased up to 150,000 kilometers.

Usually the timing belt cover is manufactured from plastic and protects not just the timing belt, but also all the other elements that are part of the gas distribution system.
