Cooling System, Charge and Bleed

  Inspect

1.   Select Opel-approved antifreeze from the parts catalogue and ensure a concentration of 50% water and 50% antifreeze. The antifreeze serves to protect the entire cooling system from freezing and also all coolant-flushed parts against rust-corrosion/calcium deposits. In tropical countries therefore you still need to add antifreeze.
2.   The water quality also plays an important role in addition to the mix ratio. Water of drinkable quality usually meets these requirements. The quality of purified sea water is inadequate!
3.   Damage may also be caused to the engine if unauthorised anti-freeze agent is used!
4.   If radiator, cylinder head or cylinder head gasket have been replaced the old coolant must not be re-used.
Important:   Vehicles with air conditioning: switch air conditioning off and set to ECO mode with ECC
5.   Open cooling system
Warning:   Cooling system is under pressure
•   Unscrew coolant expansion tank cover
6.   Fill with coolant up to lower venting line (1) at coolant expansion tank
7.   Seal off cooling system
•   Screw in coolant expansion tank cover
8.   Start engine and allow to warm up
•   Allow engine to warm up at idling speed of up to 2500 rpm until first radiator fan setting switches on
9.   Vent cooling system
•   Allow engine to run for approximately 2 minutes at 2000 to 2500 rpm
Note:   The air in the cooling system is removed via the venting lines
10.   Switch engine off and allow to cool
11.   Check coolant level and also top up coolant to "COLD" mark
