This bulletin is being issued to revise the Timing Chain, Sprockets and Tensioner Installation Procedure. Please use the following to replace the existing
information in the Engine Mechanical sub-section of the Engine Section in the 1998-2000 Service Manuals.
Procedure
1.
Install the camshaft sprockets. The sprockets are identical and interchangeable.
2.
Clean the old sealer off of the bolts with a wire brush.
3.
Clean the threaded hole in the camshaft with a nylon bristle brush.
4.
Coat the camshaft bolts with Adhesive/Sealant Compound GM P/N 1234593 or equivalent.
NOTICE:
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints,
lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping
force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts
and systems.
5.
Install the camshaft sprocket bolts and washers while holding the sprockets with J 39579.
Tighten
Tighten the bolts to 70 N.m (52 lb ft).
