Engine Flywheel Cleaning and Inspection

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean the flywheel in solvent.
  2. Dry the flywheel with compressed air.
  3. Inspect the automatic transmission flywheel for the following conditions:
    • Damaged ring gear teeth
    • Stress cracks around the flywheel-to-crankshaft bolt hole locations

      Important:  Do not attempt to repair the welded areas that retain the ring gear to the flywheel plate. Install a new flywheel.

    • Welded areas that retain the ring gear onto the flywheel for cracking
