The following procedure should be used during the installation of the seal:

1. Thoroughly clean the mating surfaces of the oil pan and cylinder block. Remove all gasket material and old sealant from the mating surfaces. Ensure that you do not scratch the mating surfaces or gouge the mating surfaces of the oil pan or the cylinder block.

2. Inspect the cylinder block oil pan flange for excessive sealant at the housing joints. Remove any excessive sealant from the area at the gasket joint for the front housing, and the area at the gasket joint for the flywheel housing.

3. Use a shop towel and a suitable solvent in order to remove engine oil and grit from the mounting surfaces. The surfaces should be clean and dry prior to installing the new seal.

4. Apply a bead of 4C-9612 Silicone Sealant to the cylinder block oil pan flange in the location of the joint for the front housing, and in the location of the joint for the flywheel housing. Ensure that the joints are completely filled with sealant.

5. Install the seal on the sealing flange of the oil pan.

6. Position the oil pan onto the engine. Install the bolts into the oil pan and tighten the bolts finger tight.

7. Torque the bolts to 70 ± 15 N·m (51 ± 11 lb ft).
