How to fill the coolant circuit
Warning! If coolant is to be added to the circuit during service, allow the engine to cool before the coolant is
added. Remove the filler cap slowly as dangerous coolant could be discharged if the coolant is still hot and the
system is under pressure.
Do not put too much coolant in the coolant circuit. There is a relief valve in the filler cap which will open and
release hot coolant if too much coolant is added.
Caution: If coolant is added to the circuit during service, it must consist of the same original mixture as used
to fill the system. See “Coolant specification” in section 5 for details of the correct coolant to be used in the
circuit.
1. Remove the filler cap (A1) of the header tank and slowly fill the coolant system until the coolant level is
approximately 12 mm (0.5 in) (A2) below the neck of the filler tube.
Note: It is necessary to vent air from the system during initial fill, or if he system has been completely drained.
To vent air, remove the plug (B1)
2. Fit the filler cap.
3. Start the engine. When it has reached its normal temperature of operation, stop it.
4. Carefully remove the filler cap of the header tank and add coolant until the level of the coolant is correct.
5. Fit the filler cap.
