Installation Procedure

2001 Chevrolet Cavalier LS, 2.4 TSECTION Installation Procedure
WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Important:  For manual transmission applications, note the position and direction of the engine flywheel before removal. The flywheel does not use a locating pin for alignment. Mark or scribe the end of the crankshaft and the flywheel before component removal. The engine flywheel must be reinstalled to the original position and direction. The engine flywheel will not initially seat against the crankshaft flange, but will be pulled onto the crankshaft by the engine flywheel bolts. This procedure requires a 3 stage tightening process.

DO NOT remove the prop shaft hub or flex plate from the automatic transmission engine flywheel. The flywheel, prop shaft hub, and flex plate are balanced as an assembly. If service is required, the entire flywheel assembly should be replaced.

  1. If equipped with a manual transmission, align the mark or scribe on the crankshaft with the mark or scribe on the existing flywheel.

    Refer to ENGINE BALANCING .
