This bulletin supersedes current and past service manual procedures and supersedes Chevrolet Dealer Service Bulletin Number 85-101, dated 07/85. All copies of 85-101 should be discarded.
A set of revised service procedures has been developed for replacement of camshaft timing gears. The revised methods do not require the complete removal of the engine from the vehicle. Cam gear replacement is generally accomplished by partially lowering the engine/cradle assembly to gain access to the cam gear.
This bulletin contains a complete procedure for servicing cam gears on Celebrity models with 2.5L engines.
