WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- 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.
- Install the spacer, if applicable, onto the rear of the crankshaft.
- Install the flywheel and bolts to the crankshaft.
- Apply threadlock to the threads of the flywheel bolts. Refer to Adhesives, Fluids, Lubricants, and Sealers for the correct part number.
- Tighten the flywheel bolts.
- Tighten the bolts (1-6) a first pass in sequence to 20 N.m (15 lb ft).
- Tighten the bolts (1-6) a second pass in sequence to 50 N.m (37 lb ft).
- Tighten the bolts (1-6) a final pass in sequence to 100 N.m (74 lb ft).
- Install the automatic transmission. Refer to Transmission Replacement for the 6L45/6L50/6L80/6L90 transmission.
NOTE:
Longer flywheel bolts must be used on applications using a flywheel spacer.
CAUTION:
Refer to Fastener Caution .
