Engine Flywheel Replacement
Removal Procedure
1. Remove the automatic transmission, if equipped.
Important: Note the position and direction of the engine flywheel before removal.
2. Remove the engine flywheel bolts.
3. Remove the automatic transmission engine flywheel.
4. Clean and inspect the engine flywheel. Refer to Engine Flywheel Cleaning and Inspection.
5. Install 2 M11x1.5 mm bolts (1) to the threaded holes of the spacer, if applicable.
6. Rotate the bolts clockwise to remove the spacer.
7. Remove the spacer from the rear of the crankshaft, if applicable.
Installation Procedure
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 (4.8 L manual transmissions or all 6.0 L) require a spacer and longer bolts for proper flywheel position.
