Cooling System Draining, Filling And Bleeding - V8 S/C 5.0L Petrol (G1269231): Filling

CAUTION: Be prepared to collect escaping coolant.

Fill the cooling system, keeping coolant to the upper level mark of the expansion tank until a steady stream of coolant is seen running from the coolant hose bleed point.
Continue to fill the coolant until the maximum level is reached.
Set the heater controls to maximum.
Start engine and increase speed to 2000rpm for 2 minutes.
1. Continue to top-up with coolant with engine idling until hot air is emitted from face vents.
1. When hot air is emitted from the vents, switch the heater off.
If no hot air is emitted, repeat step 7.
CAUTION: Correct installation of the coolant expansion tank cap can be obtained by tightening the cap until 3 audible clicks are heard.
CAUTION: Switch off the engine and allow the coolant temperature to go cold.

Switch the engine off and allow to cool.
Visually check the engine and cooling system for signs of coolant leakage.
WARNING: When releasing the cooling system pressure, cover the coolant expansion tank cap with a thick cloth.
CAUTION:
- Since injury such as scalding could be caused by escaping steam or coolant, make sure the vehicle cooling system is cool prior to carrying out this procedure
- Make sure the coolant level remains above the "COLD FILL RANGE" lower level mark.
NOTE: When the cooling system is warm, the coolant will be approximately 10mm above the upper level mark on the expansion tank with the cap removed.

Check and top-up the coolant system as required when cool.
