3. Tighten the oil pan bolts to the correct torque figure 11 - 13
Nm, in the sequence indicated.
A new oil pan is supplied with the drain plug fitted. Check
that the plug is tightened to the correct torque figure of 30 - 40 Nm.
4. NOTE: When the engine is star ted from cold and run for a
short period only, before being swit ched off, a quantity of oil will
be 'hung up' within the engine because it is not up to operating
temperature.
Should the oil level subsequently be topped-up, the level could
become too high, causing oil burning.
Typically, 0.875 L is hung up.
Lower the ramp. Refill the engine with the correct specification
engine oil.
5. Remove the paint protection sheets and close the engine
compartment.
