Oil Pan: Service and Repair

Oil pan, removing and installing

Special tools and equipment





^ 3185 Jointed wrench





^ T10058 Socket
^ Hand drill with plastic brush attachment
^ Silicone sealing compound D 176 404 A2

Removing
^ Remove center and right sound insulation trays:
^ Drain engine oil.

Note: Observe waste disposal regulations!

^ Remove oil pan bolts using jointed wrench 3185. Remove bolts to bellhousing using socket T1 0058.
^ Remove oil pan. It may be necessary to release pan by using light blows with a rubber headed hammer.
^ Remove sealant residue from cylinder block with a flat scraper.





^ Remove sealant residue from oil pan with a rotating brush, e.g. a hand drill with a plastic brush attachment (wear eye protection).
^ Clean sealing surfaces. They must be free of oil and grease.

Installing

Note:
^ Note the use-by-date of the sealant.
^ The oil pan must be installed within 5 minutes of applying silicone sealing compound.





^ Cut off tube nozzle at front marking (nozzle approximately 3 mm diameter).
^ Apply silicone sealing compound as shown to clean pan sealing surface. Sealing compound bead must be:
^ 2...3 mm thick
^ and run on inside of bolt holes (arrows)

Note: The sealing compound bead must not be thicker, otherwise excess sealing compound will enter the pan and may block the oil suction pipe strainer.





^ Sealing compound bead must be applied carefully in areas marked by arrows. (Illustration shows position of sealant bead on cylinder block).
^ Install oil pan immediately and tighten bolts as follows:
1- Tighten all pan/cylinder block bolts lightly using diagonal sequence.
2- Tighten three pan/transmission bolts lightly.
3- Tighten all pan/cylinder block bolts lightly using diagonal sequence again.
4- Tighten pan/transmission bolts to 45 Nm.
5- Tighten all pan/cylinder block bolts to 15 Nm using diagonal sequence.

Note:
^ When installing the oil pan on an engine which is removed from the vehicle, ensure that the oil pan is Rush with the cylinder block on the flywheel end.
^ The sealant must be allowed to cure for approximately 30 minutes after installing the oil pan. After this time the engine may be filled with engine oil.

The rest of the assembly is basically in reverse order to the removal sequence.
