1. Unscrew the plug ( A-Fig.1) of the expansion tank and top up with the prescribed type of coolant (000300) up to
50 ÷ 60 mm from the base of the cap.
2. Start the engine and run it at idle speed for some minutes leaving the radiator expansion tank plug open.
3. Adjust the air conditioner control to maximum heat and maximum fan speed (B-Fig.2); stop the engine and
check the coolant level through the radiator expansion tank plug; top up with coolant if necessary.
4. Close the cap
5. Wait for the engine to cool down (to below 80°C) and top up the coolant tank (Nourice) with the missing coolant.
6. Then tighten the radiator expansion tank plug.
