Service, Maintenance 231
When the engine is at op erating
temperature, coolant level rises. It falls
again when the system cools. If it falls
below the KALT/COLD mark when the
system is cold, top up to the mark.
Top up anti-freeze. If no anti-freeze is
available, top up with clean tap water. If
tap water is unavailable, distilled water
can be used.
After filling with tap water or distilled
water, measure the anti-freeze
concentration and add anti-freeze if
required. Have a workshop establish the
cause of the coolant loss.

Too low a coolant level can cause engine
damage.
Anti-freeze and corrosion protection
Coolant level
Before the start of winter, have a workshop
check the a nti-freeze protection. The anti-
freeze level must guarantee protection
down to approx. -28 °C. Insufficient anti-
freeze will reduce the frost protection level
and the corrosion protection. If necessary,
add anti-freeze.
Hardly any losses occur since the cooling
system is sealed, and it is thus rarely
necessary to top up the coolant.
To close, position the cap and screw it into
place.
The coolant should be a little above the
KALT/COLD mark in the expansion tank
with a cold cooling system. The coolant
level can also be read off from the outside
of the expansion tank.
If coolant loss is topped up with water,
have concentration checked and add anti-
freeze if necessary.
9 Warning
Allow engine to cool down before
removing coolant filler cap. Remove
coolant filler cap carefully so that
pressure can escape slowly, otherwise
there is a risk of scalding.
