The level can only be checked properly when the engine is not

running.

The coolant level must be between the m m a a x x and m m i i n n marks on the

expansion tank when engine is cold and can be slightly above the

m m a a x x mark when it is warm.

Coolant losses

Coolant loss normally indicates leaks in the system. In this case

the cooling system should be checked by a Technical Service

Center without delay. It is not sufficient merely to add coolant.

In a sealed system losses can only occur if the boiling point of the

coolant is exceeded as a result of overheating, and coolant is

forced out of the system.

Topping up coolant

Switch engine off and let it cool down. Then cover expansion tank

cap with a cloth and turn cap carefully anti-clockwise and remove.

No other coolant may be used if G G 1 1 2 2 + + is not available. In this

case only water can be used and the correct mixture concentration

must be restored with the specified coolant additive (see previous

page) as soon as possible.
