Checking coolant level/adding coolant
The expansion tank for the coolant is located un-

When the
engine is cold and the car is level, the
coolant level must lie between the min- and max-
marks.
Checking when engine is cold
1. Remove cover.
2. Open cap of the expansion tank carefully and
allow any overpressure to escape.
Then unscrew cap completely.
3. Read the coolant level.
4. Top up with coolant if necessary.
Do not exceed the max- mark.
Only add a mixture of anti-freeze and water in
equal parts.
Antifreeze in coolant:
50% provides anti-freeze protection down to
-31 °F (-35 °C).
5. Screw the cap closed firmly and put on the
cover.
