Customer Care and Aftersales is pleased to announce
the release of three timing chain service kits for the
High Feature V6 engine applications available for use
as of April 2012. These comprehensive timing chain
kits were designed to fulfill all the parts requirements
necessary while servicing High Feature V6 engine
applications from 2007 to 2012. These kits were
developed with the latest product enhancement in
mind, while reducing vehicle downtime for our
customers at a very competitive price. These kits
contain all of the necessary parts for repairing worn
timing chains minus the RTV sealer and timing chain
guides.
These kits should be used on vehicles covered under
the terms of the Powertrain Warranty coverage, Special
Coverage terms. Please do not order or use parts
separately while repairing a vehicle covered by
warranty.
These kits do not contain idler sprockets, camshaft
actuator gears, crankshaft driven gear or the chain
guides as these parts should not be replaced for a
stretched timing chain setting DTCs P0008, P0009,
P0016, P0017, P0018 and/or P0019. Idler gears,
camshaft actuators, crankshaft driven gears and timing
chain guides are being replaced unnecessarily and are
not worn and should not be replaced.
If this concern is encountered, follow the guidelines
below to install the necessary timing chain service kit:

surface is worn down into the base friction material,
leaving friction wear witness marks. Refer to the above
pictures showing an example of normal wear (1) which
should not be replaced, and a worn guide (2) which
