To install:

  1. Clean all parts well. If there is evidence of oil leaking past the rear crankshaft oil seal, replace the oil seal using the procedures found in this section. Examine the teeth around the other edge of the wheel where the starter engages. If they are worn or damaged, replace the flywheel.
  3. Flywheel bolts may have thread-locking adhesive on the threads. If the bolts must be reused, clean the threads on the bolts and in the crankshaft.
  5. Apply fresh thread-locking compound to all of the flywheel-to-crankshaft bolts.
  7. The remaining installation steps are the reverse of the removal procedure. Tighten the flywheel bolts evenly. Final torque should be:
    1. 3.1L and 3.4L engines: 60 ft. lbs. (82 Nm)
    3. 3.5L and 3.8L engines: Tighten to 11 ft. lbs. (15 Nm) plus an additional 50 degrees. NEW BOLTS ARE MANDATORY.

  9. Install the transaxle.
