Installation Procedure

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

The flywheel does not use a locating pin for alignment and will not initially seat against the crankshaft flange or spacer (if applicable), but will be pulled onto the crankshaft by the engine flywheel bolts. This procedure requires a three stage tightening process.
Certain applications (6.0L) require a spacer and longer bolts for proper flywheel position.

IMPORTANT: Longer flywheel bolts must be used on applications using a flywheel spacer.

Install the automatic transmission engine flywheel to the crankshaft.
Apply threadlock to the threads of the flywheel bolts. Refer to Sealers, Adhesives, and Lubricants for the correct part number.
