Special tools, workshop equipment, and other items required

• ◆ Electric drill with plastic brush attachment
• ◆ Protective goggles
• ◆ Silicone sealant D 176 404 A2

Removing

• ‒ → Remove lower air duct pipe -arrows-.

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

• ‒ → Unscrew bolts of oil pan/gearbox -arrows-.
• ‒ Slacken bolts -1 ... 20- diagonally.

Note:

Loosen and tighten oil pan bolts with jointed wrench 3185. Unscrew using socket attachment 3249.

• ‒ Remove sump: if necessary loosen it by striking lightly with a rubber hammer.

• ‒ Carefully remove sealant residues from cylinder block. For this 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.

Installing

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

• ‒ → Cut off nozzle of tube at front marking (ø of nozzle approx. 3 mm).

• ‒ → Apply the bead of silicone sealant onto the clean sealing surface of the oil pan, as illustrated.
• ‒ Thickness of sealant bead: 2 ... 3 mm

Notes:

• ◆ The oil pan must be installed within 5 minutes after applying the silicone sealant.
• ◆ The bead of sealant must not be thicker than prescribed, as otherwise excess sealant will enter the oil pan and obstruct the strainer in the oil intake manifold.
• ◆ 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:
• ‒ → Tighten 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 oil pan with the engine out of the vehicle, ensure that the oil pan is flush with the cylinder block at the flywheel end.
• ◆ After fitting oil pan assembly, the sealant must dry for approx. 30 minutes. Only then may the engine oil be filled.

• ‒ Fill up with engine oil and check oil level.
