Oil Pump And Lower Oil Pan Overview
CAUTION:
Danger of catalytic converter damage.
- The oil level must not exceed the "MAX" marking.
NOTE:
If large quantities of metal particles or abraded material are detected during engine repairs, it may mean the crankshaft or rod bearings are damaged. To prevent subsequent damage, the following work must be performed after the repair: Oil channels must be cleaned carefully; replace oil spray jets, engine oil cooler and oil filter.
Oil capacities, specifications and viscosity classes, refer to the Fluid Capacity Tables .

-- Tighten bolts in 3 stages as follows:
| Step | Tightening Torque/Additional Angle of Rotation |
|---|---|
| 1. | 5 Nm in a diagonal sequence |
| 2. | 8 Nm in a diagonal sequence |
| 3. | In a diagonal sequence, turn an additional 90° |
