Repair procedures are under constant review, and therefore times are subject to change; those quoted here must be taken as guidance only.
Always refer to DDW to obtain the latest repair time.
DDW requires the use of causal part numbers. Labor only claims must show the causal part number with a quantity of zero.
REPAIR PROCEDURE
VERIFY COOLANT LEVEL
WARNING:
Follow GTR and general workshop safety procedures when working on the engine cooling system.
1. Remove the coolant expansion tank cap.
NOTE:
View the expansion tank from the side, not the top.

3. If the engine temperature is cold (gauge on 'C') the coolant level must be at the top of the 'COLD FILL RANGE'. (Figure 2)
^ If necessary, top up the cooling system to the correct level with coolant.
4. If the engine temperature is normal (gauge on 'Normal') the level must be 30 mm (1.2 min) above the top of the 'COLD FILL RANGE'.
(Figure 2)
^ If necessary, top up the cooling system to the correct level with coolant.
BLEEDING THE COOLING SYSTEM / VERIFY COOLANT LEVEL
1. Bring engine to normal operating temperature:
^ Raise engine to 3,000 rpm for one minute.
