TIPS AND MAINTENANCE
Coolant l l osses
Coolant loss normally indicates leaks in
the system. In this case the cooling sys-
tem should be checked by a Technical
Service Centre without delay. It is not suf-
ficient 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 u u p c c oolant
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 G12+ is
not available. In this case only water can
be used and the correct mixture concen-
tration must be restored with the speci-
fied coolant additive (see previous page)
as soon as possible.
