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 just above the
ma rk .
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 topping up with water or distilled
water, check the antifreeze concentration
and a dd antifreeze if necessary. H ave a
workshop eliminate the c ause of the
coolant loss.
Too low a coolant level can cause engine
dam age.
To close, position the cap and screw it into
place.

cap carefully so that p ressure can escape
