- Clean sealing surfaces. They must be free of oil and grease.

Installing

• Note the expiration date of the sealant.

• The oil pan must be installed within 5 minutes after applying the silicone sealant.

- Cut tube nozzle at front marking (nozzle dia. approximately 3 mm).





• The sealant bead must not be thicker than 2 to 3 mm or excess sealant could get into oil pan and clog the oil intake pipe strainer.

- Apply silicone sealant, as shown, to clean oil pan sealing surface. The sealing compound bead must be:

• 2 to 3 mm thick

• Run around inside of bolt holes - arrows -

- Apply silicone sealant to the clean oil pan sealing surfaces as illustrated. (The illustration shows the location of the sealant bead on the cylinder block.)





- Position the oil pan immediately and tighten the bolts connecting the oil pan and transmission and all of the oil pan bolts. Make sure the oil pan lies flush on the intermediate plate/transmission flange.

• When installing the oil pan to a removed engine, make sure that the oil pan is positioned flush with the cylinder block on the flywheel side.

- Tighten oil pan bolts in a diagonal sequence.

• Tightening specifications: --> [ (item 23) 15 Nm ] Oil Pump, Oil Pan and Balance Shaft Module.

- Tighten oil pan/cylinder block bolts.

• Tightening specifications: --> [ (item 21) 40 Nm ] Oil Pump, Oil Pan and Balance Shaft Module.

- Tighten oil pan/transmission bolts.

• Tightening specifications: --> [ (item 22) 45 Nm ] Oil Pump, Oil Pan and Balance Shaft Module.

• After installing the oil pan, allow the sealant to dry for approximately 30 minutes. Only after then may the engine oil be replenished.

Further installation is in reverse order.
