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.

AUTION:
When releasing the belt tension, never apply any torque in a clockwise direction to the pulley
centre bolt (left hand thread) as it could subsequently loosen.
Remove the drive belt from the generator and accessory drive. 1. Use a spanner e.g. Churchill JD-230 or Snap On XDHM 1415, on the centre bolt of the belt tensioner idler pulley, to turn the adjuster assembly to the left against spring tension.

2.
Whilst holding the tensioner against spring tension, remove the drive belt from the generator pulley.
Release the tensioner slowly and remove the spanner.
 Disconnect the belt from the other pulleys, as necessary, to move it clear of the pump pulley.
4.
Remove the pulley from the water pump.
1. remove the pulley securing screws.
2. Remove the pulley from the water pump.
 Clean relevant parts and faces.
