Timing Chain: Service and Repair
Replace - Engine Installed
TIMING CHAIN REPLACEMENT - Engine Installed
CAUTION: In order to replace the chain with the engine installed in the vehicle, the chain guides and camshaft sprockets must be in good condition.
Inspect both items with the chain tensioner and camshaft cover removed prior to performing any additional work.
NOTE: A worn timing chain can result in a customer complaint of chain rattle and/or chatter. Fluctuations in timing may also occur on cars with an
EZK (TZ59) ignition system, which can cause driveability or detonation complaints. When the chain wears and stretches, the chain tensioner
compensates for this at the ratcheting mechanism allows movement in this manner. Should you have a customer complain of chain noise, the chain can
be replaced with a service chain developed for this purpose. Follow the Action outlined below.
