Installation Procedure
1. Notice: Refer to Fastener Notice in Service Precautions.
Important: The alignment of the structural oil pan is critical. The rear bolt hole locations of the oil pan provide mounting points for the
transmission housing. To ensure the rigidity of the powertrain and correct transmission alignment, it is important that the rear of the block and the
rear of the oil pan are flush or even. The rear of the oil pan must NEVER protrude beyond the engine block and transmission housing plane. Do
NOT use the oil pan gasket again. It is not necessary to rivet the NEW gasket to the oil pan.
Install the oil pan baffle and bolts.
Tighten the oil pan baffle bolts to 12 Nm (106 inch lbs.).
2. Apply sealant GM P/N 12346004 (Canadian P/N 10953480) or equivalent to the threads of the oil pan oil gallery plugs.
