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 reuse the oil pan gasket. |
• | It is NOT necessary to rivet the NEW gasket to the oil pan. |
- Apply a 5 mm (0.20 in) bead of sealant , or equivalent 20 mm
(0.80 in) long to the engine block. Apply the sealant directly onto the tabs of the front/rear cover gasket that protrudes into the oil pan surface. Refer to
Adhesives, Fluids, Lubricants, and Sealers
for the correct
part number.
Important: Be sure to align the oil gallery passages in the oil pan and engine block properly with the oil pan gasket.
- Pre-assemble the oil pan gasket to the pan.
2.1. | Install the gasket onto the pan. |
2.2. | Install the oil pan bolts to the pan and through the gasket. |
Notice: Refer to Fastener Notice in the Preface section.
