Installing
• Note the expiration date of the silicone sealant.
• The oil pan must be installed and tightened immediately after application of the silicone sealant.
- Cut the sealant tube nozzle at the front mark (nozzle diameter: approximately 3 mm).
- Apply the silicone seals as illustrated. The sealant bead must be:
• 2 to 3 mm thick
• and run on the inside of the bolt holes - arrows -
• The sealant bead must not be thicker than specified. Otherwise, the excess sealant could get into the oil pan and clog the strainer in the oil intake pipe.
• With the transmission removed, the oil pan must seal flush with the cylinder block.
• With the transmission installed, the oil pan must make contact on the transmission.
• After installing the oil pan, allow the sealant to dry for approximately 30 minutes. Only after then may the engine oil be added.
- Immediately position the oil pan and tighten the bolts as follows:
1 Tighten all bolts of the oil pan to cylinder block very lightly in a diagonal sequence.
2 Tighten the oil pan to transmission bolts lightly.
3 Tighten the oil pan to cylinder block bolts again, lightly in a diagonal sequence.
4 Tighten the oil pan to transmission bolts to 40 Nm.
5 Tighten the oil pan to cylinder block bolts in a diagonal sequence to 15 Nm.
Further installation is in the reverse order of removal.
