Installing
Installation is the reverse of removal, noting the
following:

- Clean sealing surfaces so they are completely
free of any oil or grease.

WARNING!

Wear protective glasses.

Note:
After applying silicon sealant D 454 300 2, oil pan must be installed within
5 minutes. - Using rotating plastic brush, remove any remaining sealant from oil
pan.

Note:
Sealant must not be thicker than 3 mm, otherwise excess sealant may get
into the oil pan and clog the oil intake strainer. - Cut tube jet at front marking (jet diameter approx. 3 mm).
Thickness of sealant: 2-3 mm (0.04-0.12 in.)
