Good To Know

Q: What does a timing cam chain do? A: It links the crankshaft and camshaft so valves open and close in time with piston movement. A worn or stretched chain can cause rough running or timing faults.

Q: Should I replace the timing cam chain alone? A: Many technicians also inspect the tensioner and sprockets at the same time. Wear on those parts can shorten the life of a new chain.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
