=> Parts List

Removing

• ‒ → Remove air duct pipe from right longitudinal member -arrows-.

• ‒ → Remove noise insulation in centre and on right -arrows-.
• ‒ Drain engine oil.

• ‒ → Detach connector from oil level sender -arrow-.

• ‒ → Unscrew bolts of oil pan/gearbox -arrows-.
• ‒ Slacken bolts -1 ... 20- diagonally.
• ‒ Take off sump: if necessary loosen it by striking lightly with a rubber hammer.

Note:

→ The two rear oil pan bolts -1- and -2- are accessible via the recess

-arrow- on the flywheel -3- (turn the flywheel as required).

Installing

Installation is carried out in the reverse order; note the following:

• ‒ Carefully remove sealant residues from cylinder block. For this purpose, remove baffle plate.
• ‒ → Remove sealant residues from oil pan, e.g. with rotating plastic brush or similar.

• ‒ Clean sealing surfaces: they must be free of oil and grease.

Note:

The sump must be installed within 5 minutes after applying the silicone sealant.

• ‒ → Cut off nozzle of tube at front marking (ø of nozzle approx. 3 mm).
• ‒ Sealant bead width - arrows-: 2 ... 3 mm

Note:

The bead of sealant must not be thicker than 3 mm, as otherwise excess sealant will enter the sump and obstruct the strainer in the oil intake manifold.

• ‒ → Apply the bead of silicone sealant onto the clean sealing surface of the sump, as illustrated. (The illustration shows the position of the sealant bead on the cylinder block).

Note:

Be particularly careful when applying the bead of sealant around the rear sealing flange (arrows in illustration).

• ‒ Immediately install oil pan and tighten bolts in the sequence mentioned:
• ‒ → Unscrew bolts -1 ... 20- diagonally to 5 Nm.
• ‒ Tighten bolts of oil pan/gearbox -arrows- to 45 Nm.
• ‒ Tighten bolts -1 ... 20- diagonally to 15 Nm.

Notes:

• ◆ When installing the sump with the engine out of the vehicle, ensure that the sump is flush with the cylinder block at the flywheel end.
• ◆ After fitting sump assembly, the sealant must dry for approx. 30 minutes. Only then may the engine oil be filled.

• ‒ → When installing air duct pipes with connectors, ensure that the securing clip -arrow- engages audibly in the retaining lug -A-.
• ‒ Fill up with engine oil and check oil level.
