BLEEDING COOLING
SYSTEM

Bleeding is absolutely necessary after
refilling the cooling system.
Bleeding is also recommended, if
coolant is added after the expansion
tank had been emptied.

Caution!
Danger of scalding! Only unscrew cap
from expansion tank when engine is
cold.

Set heater controls to warm.
Fill system and simultaneously unscrew
the bleeder screw on the thermostat
housing, tightening it again
when the escaping coolant is without
air bubbles.

Fill expansion tank and screw on cap.
Run engine to operating temperature
(2500 rpm engine speed).

Check level of coolant in the expansion
tank after running engine, correcting
if necessary.
The mark indicates the full level at
20° C (68° F).
Only use specified coolant*.
