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 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.


Apply a 5 mm (0.2 in) bead of sealant 20 mm (0.8 in) long to the engine block. Refer to Sealers, Adhesives, and Lubricants for the correct part number. Apply the sealant directly onto the tabs of the front cover gasket that protrude into the oil pan surface.

Note that some of this may seem confusing, since the transmission in a C6 is in the rear, not bolted directly to the engine. The parts the book calls left and right transmission covers aren't attached to the transmission, or anywhere near the transmission. They are close off plates for the bellhousing. The bellhousing does bolt to the engine, and contains the clutch (or flexplate coupling for automatics).
