Antifreeze and corrosion protection
Before the start of winter, have a w orkshop
check the a ntifreeze protection. The
antifreez e lev el must guarantee protection
to approx. -28 ° C. Insuffic ient antifreez e
will reduc e the frost protec tion level and
the c orrosion p rotection. If necessary add
antifreez e.
If coolant loss is topped up with water,
have concentration checked and add
antifreez e if necessa ry.
Coolant level
Hardly a ny losses occur since the cooling
system is sealed and it is thus rarely
necessary to top up the coolant.
The coolant should be a little above the
KALT/COLD ma rk in the expansion tank
with a cold cooling system. The coolant
level can also be read off from the outsid e
of the expansion tank.
When the engine is at op erating
temperature, coolant lev el rises. It falls
aga in when the system cools. If it falls
below the KALT/COLD mark when the
system is cold, top up to the mark.
Top up a ntifreeze. If no antifreeze is
av ailable, top up with clean tap water.
If tap water is unavailab le, distilled water
can b e used.
After filling with tap water or d istilled
water, measure the antifreeze
concentration and ad d antifreez e if
required. H ave a workshop establish the
cause of the coolant loss.
Too low a coolant level can cause engine
dam age.
To close, position the cap and screw it into
place.

Warning
Allow engine to cool down before
rem ov ing coolant filler cap. Remove filler
cap carefully so that pressure can escape
slowly, otherwise there is a risk of scalding.
