Description

Timing Belt Tensioner for the 200TDi 2.5L turbo diesel engine, part of the camshaft timing belt drive.

The tensioner maintains correct tension on the toothed timing belt, keeping it in accurate mesh with the crankshaft, camshaft and injection pump sprockets and preventing tooth jump. A worn bearing or weakened tensioner lets the belt slacken, risking mistiming; on this interference engine a failed belt allows valve-to-piston contact. Replacement is recommended whenever the timing belt is renewed.
