50. Oil Pan 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, it may not be moved as this will not allow the sealant to function properly 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. Apply a 2 mm (0.08 inch) bead of Loctite (R) 5900 (or equivalent) 3 mm from the edge of the oil pan.

IMPORTANT: If the repair is being performed out of vehicle, attach the transaxle nose cone bracket to engine block and use strait edge at the transaxle-to-engine mating flange for positive oil pan alignment to the engine block.





3. Assemble oil pan to engine block.
a. Use the transaxle nose cone as guide for fore/aft alignment.
b. Use the transaxle-to-engine block (or straight edge if transaxle is removed) as left/right alignment.
c. Install nose cone bracket-to-oil pan bolts and tighten finger tight in order align fore/aft position.
d. Install transaxle-to-oil pan bolts and tighten finger tight in order to align right/left position. (If transaxle is not installed, use straight edge for alignment.)
e. Install oil pan bolts with Loctite (R) 247 Threadlocker or equivalent.
