WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean the rear main cap mating surfaces including the oil pan gasket groove.
  2. Carefully install a new upper seal. Refer to UPPER SEAL-CRANKSHAFT INSTALLED .
  3. Lightly oil the new lower seal lips with engine oil.
  4. Install a new lower seal in bearing cap with the white paint facing the rear of engine.
  5. Apply 5 mm (0.20 in.) drop of Mopar® Gasket Maker, or equivalent, on each side of the rear main bearing cap (Figure). DO NOT over-apply sealant or allow the sealant to contact the rubber seal. Assemble bearing cap to cylinder block immediately after sealant application.
  6. To align the bearing cap, use cap slot, alignment dowel, and cap bolts. DO NOT remove excess material after assembly. DO NOT strike rear cap more than two times for proper engagement.
  7. Install the rear main bearing cap with cleaned and oiled cap bolts. Alternately tighten the cap bolts to 115 N.m (85 ft. lbs.) torque.
  8. Install oil pump (Refer to ENGINE/LUBRICATION/OIL PUMP-INSTALLATION ).
  9. Apply Mopar® GEN II Silicone Rubber Adhesive Sealant, or equivalent, at bearing cap-to-block joint to provide cap to block and oil pan sealing. Apply enough sealant so that a small amount is squeezed out. Withdraw nozzle and wipe excess sealant off the oil pan seal groove.
  10. Immediately install the oil pan (Refer to ENGINE/LUBRICATION/OIL PAN-INSTALLATION ).
