Installing
- Observe the use by date of the sealant.
- The oil pan must be installed within 5 minutes of applying silicone sealing compound.
- Cut off tube nozzle at front marking (nozzle approx. 3 mm diameter).
- Apply silicone sealing compound, as shown, to clean oil pan sealing surface. Sealing compound bead must be:
2 to 3 mm thick
and run on inside of bolt holes (arrows)
- Apply sealing compound bead carefully to areas marked by (arrows).
- Install oil pan immediately and tighten bolts as follows:
- When installing the oil pan on an engine which is removed from the vehicle, ensure that the oil pan is flush with the cylinder block on the flywheel end.
- The sealant must be allowed to cure for approx. 30 minutes after installing the pan. After this time the engine may be filled with engine oil.
1 - Tighten all oil pan/cylinder block bolts lightly using a diagonal sequence.
2 - Tighten three oil pan/transmission bolts lightly.
3 - Tighten all oil pan/cylinder block bolts lightly using a diagonal sequence again.
4 - Tighten oil pan/transmission bolts to 45 Nm.
5 - Tighten all oil pan/cylinder block bolts to 15 Nm using a diagonal sequence.
Oil pan, lower part
- Observe the use by date of the sealant.

- Sealing compound bead must be: A = 2 to 3 mm thick
- Run sealing compound bead along inner side of bolt holes (arrows)
Engines with oil pan guard
- Check condition of rubber bushings in cylinder block (for mounting spreader rivets) before installing oil pan cover.
- Before bolts are reinstalled, clean threads and apply sealant D 000 600 A2.
- Insert spreader pin flush with spreader rivet -4- and install in oil pan cover -1-.
- Tighten bolts -2- in front and rear ends of oil pan to 37 Nm.
Continued for all engines
