How to fill the engine and charge cooler cooling system (when fitted)

Combined engine and charge cooler radiator systems are normally supplied for individual installations. A
separate radiator may be used by an OEM. The engine operator must be aware of the filler cap position.
Caution: All trapped air must be vented from the cooling systems. 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 preventative, must be used in the
engine and charge cooler systems, see "Coolant specification" on page 60.
Warning! Always stop the engine and allow the pressurised system to cool before removing the filler cap.
Avoid skin contact with the coolant mixture.
To fill the engine system
1 Remove the vent plug (A1) from the pipe connecting the water rail to each thermostat.
2 Remove the radiator filler cap (B1). Fill the radiator until air free coolant flows from the vent.
3 Refit the vent plugs and continue filling until the coolant is 25 mm (1") below the filler neck (B2).
To fill the charge cooler system
1 Remove the charge cooler vent plugs (C1).
2 Remove the radiator filler cap (B1). Fill the radiator until air free coolant flows from the vent.
3 Refit the vent plugs and continue filling until the coolant is 25 mm (1") below the filler neck (B2).
