-- Apply the silicone sealing compound D 176 501 A1, as shown, to the clean oil pan sealing surface. The sealing compound bead must be:

2 to 3 mm thick.
and run on the inside of the bolt holes -arrows-.

NOTE:

Sealant bead must not be thicker than specified. Otherwise, excess sealant could get into oil pan and clog the strainer in the intake side of the oil pump.

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

-- Tighten the oil pan bolts to 12 Nm.

-- Tighten the oil pan/transmission bolts to 45 Nm.

The rest of the assembly is basically a reverse of the removal sequence.
