Oil Pan Replacement: Installation

IMPORTANT:  Alignment of the oil pan is critical to ensure transaxle nose cone-to-oil pan and transaxle mating flange-to-oil pan alignment. Application of RTV is critical to ensure positive seal of the chamfered sealing flange on the oil pan-to-engine block mating surface. After pan has been placed on the engine block, do not allow pan to move as this will not allow the sealant to properly seal in the chamfered flange.

1. Clean oil pan and engine block sealing flanges with a chlorinated solvent such as carburetor spray cleaner, brake clean, or alcohol Saturn P/N 21007432 (or equivalent).
2. Install oil pan alignment pins J44715 into datum holes as shown in illustration. Tighten until firmly seated in block.

   3. Install enough oil pan bolts to retain oil pan into position and remove oil pan alignment pins J44715.
