^ Protective glasses
^ Flat scraper

Removing
- Removing center and right insulation tray:
- Drain engine oil.

Note: Observe disposal regulations!

- Detach turbocharger oil return pipe from oil pan.
- Loosen oil pan bolts using extension socket wrench 3185. Unscrew with socket 3249.
- Remove oil pan; it may be necessary to release oil pan by tapping lightly with a rubber head hammer.
- Remove sealant residue on cylinder block with a flat scraper.





- Remove sealant residue on oil pan with a rotating brush, e.g. a hand drill with a plastic brush (wear protective glasses).
- Clean sealing surface; it must be free of oil and grease.

Installing

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





- Cut off tube nozzle at forward marking (nozzle approximately 3 mm diameter).
- Apply silicone sealing compound, as shown, to clean oil 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 oil pan and may block the oil suction pipe strainer.





- Apply silicone sealing bead as shown to clean sealing surface of oil pan (illustration shows position of sealant bead on cylinder block).
- Install oil pan immediately and tighten bolts as follows:
1. Tighten all bolts oil pan/cylinder block very lightly and diagonally.
2. Lightly tighten three bolts oil pan/transmission.
3. Lightly tighten all bolts oil pan/cylinder block diagonally.
4. Tighten three bolts oil pan/transmission to 45 Nm.
5. Tighten all bolts oil pan/cylinder block diagonally to 15 Nm.
6. Tighten oil pan/oil return pipe to 10 Nm.

Note:
^ When installing the oil pan on an engine which is out of vehicle, ensure that the oil pan is Rush with cylinder block on flywheel end.
^ The sealant must be allowed to dry for approximately 30 minutes after installing the oil pan before the engine can be filled with engine oil.
The rest of the assembly is basically a reverse of the disassembly sequence.
