Installation Procedure
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
bellhousing. 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 must NEVER protrude beyond the engine block and transmission bellhousing plane.
-
Do not reuse the oil pan gasket.
-
It is not necessary to rivet the NEW gasket to the oil pan.
1. Apply a 5 mm (0.20 inch) bead of sealant GM U.S. P/N 12378190, or equivalent 20 mm (0.80 inch) long to the engine block. Apply the sealant
directly onto the tabs of the front cover gasket that protrudes into the oil pan surface.
