For 1990-2009 cars

### 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.

Important: The original oil pan gasket is retained and aligned to the oil pan by rivets. When installing a new gasket, it is not necessary to install new oil pan gasket rivets.

It is not necessary to rivet the NEW gasket to the oil pan.
1. Apply a 5 mm (0.2 in) bead of sealant 20 mm (0.8 in) long to the engine block (1). Apply the sealant directly onto the tabs of the front cover gasket that protrude into the oil pan surface. Refer to Adhesives, Fluids, Lubricants, and Sealers.
2. Apply a 5 mm (0.2 in) bead of sealant 20 mm (0.8 in) long to the engine block (1). Apply the sealant directly onto the tabs of the rear cover gasket that protrude into the oil pan surface. Refer to Adhesives, Fluids, Lubricants, and Sealers.

Important: Be sure to align the oil gallery passages in the oil pan and engine block correctly, with the oil pan gasket.

3. Preassemble the oil pan gasket (2) to the oil pan (3).

3.1. | Install the oil pan gasket (2) to the oil pan (3).

3.2. | Install the oil pan retaining bolts (1) to the oil pan (3) and through the oil pan gasket (2).

4. Tighten the oil pan to cylinder block retaining bolts (1) finger tight. Do not over tighten.
5. Tighten the oil pan to engine rear cover retaining bolts (2) finger tight. Do not over tighten.
6. Place a straight edge across the rear of the engine block and the rear of the oil pan at the transmission housing mounting surfaces.
7. Align the oil pan until the rear of engine block and the rear of oil pan are flush or even.
8. Measure the oil pan-to-engine block alignment.

8.1. | Place a straight edge across the rear of the engine block and rear of the oil pan at the transmission housing mounting surfaces.

| Important: The rear of the oil pan must NEVER protrude beyond the engine block and transmission housing mounting surfaces.

8.2. | Insert a feeler gauge between the straight edge and the oil pan transmission housing mounting surface and check to make sure that there is no more than a 0.25 mm (0.01 in) gap between the pan and the straight edge.

8.3. | If the oil pan alignment is not within specifications, remove the oil pan and repeat the above procedure.

Notice: Refer to Fastener Notice in the Preface section.
