Product specifications

Product Description

Function​
Tension Maintenance: The timing chain tensioner, with the OE number 079109217J, is responsible for maintaining the correct tension on the timing chain. In an engine, the timing chain connects the crankshaft to the camshaft(s). Proper tension ensures that the chain doesn't become loose, which could lead to issues like jumping teeth. A loose or misaligned timing chain can cause engine damage, disrupt the engine's firing sequence, and result in poor engine performance, including misfires and reduced power output.
