How to fill a CHP type cooling system
The siting of the cooling system filler cap and air vent plugs is dictated by each OEM’s individual installation.
The operator must be aware of their position.
Caution: All trapped air must be vented from the engines cooling system. If an airlock is present on engine
start up localised overheating will occur, possibly causing engine damage.
Note: A solution of clean water and anti-freeze, or clean water and corrosion inhibitor, must be used in the
cooling system. Refer to "Coolant specification" on page 43.
Warning! Always stop the engine and allow the pressurised system to cool before removing the filler cap.
Avoid skin contact with the coolant mixture.
1 Remove the cooling system filler cap (A1).
2 Loosen the appropriate air vent plugs.
3 Fill the cooling system until air free coolant flows from the vent plugs.
4 Stop filling and tighten the vent plugs.
5 Fill the cooling system to 25 mm (1 inch) (A2) below the filler neck.
6 Replace the filler cap.
