General Procedures section of the cooling system.
30. 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.
Refill the engine with the correct specification engine oil.
31. Connect the battery and in stall the battery cover.
Refer to the Battery Reconnection Procedure 86.15.15.
32. Check the oil level and start th e engine. Check for leaks and
that the engine runs correctly.
33. Install the engine compartmen t cover. Refer to Operation
76.16.01.
34. Remove the paintwork protection sheets and close the engine
compartment cover.

A coola n
t drain plug is located at the rear of the cylinder block.
Coolant may be drained from the A-bank, by removing the coolant pipe from behind the starter motor.
For vehicles fitted with the cold climate package, a cylinder block heater (shown) replaces the drain plug located on the B-
bank.
Coolant Pump and Flow Control

The coolant pump is fitted between the two cylinder banks, on the front face of the cylinder block.
The pump consists of a housing containing a shaft, with a sh rouded plastic impeller on one end and a drive pulley on the
other.
A pair of roller bearings support the shaft in the housing. A seal behind the impeller prevents coolant from contaminating the
bearings. Should this seal fail, coolant escapes from a witness hole in the housin g indicating that immediate action is
required.
An O-ring and an aluminum-alloy gasket, seal the ports between the pump and the cylinder banks.
