Antifreeze and corrosion protecti on
Be fore the start of the cold we ather se ason,
have the coolant che cked for corre ct
concentration.
T h e a m o un t o f a n t i f r ee ze m u st p r ov i de
protection up to ap prox . – 28 °C . If the
antifre ez e conce ntration is too low, this
red uces protection from freezing and
corrosion. Top up antifre eze if nece ss ary.
If coolant loss is toppe d up with wate r,
have concentration checke d and add
a n t i - f re ez e i f n e ces sa ry .Coolant lev el
Hardly a ny loss es occur s ince the cooling
sy ste m is se aled and it is thus rare ly
ne cessary to top up the coolant.
The coolant should be just ab ov e the arrow
marke d CO LD F IL L in the e xpansion tank
with a cold cooling s ys tem. The coolant
leve l can be rea d from the outs ide of the
exp ansion tank.W h en t h e en g i n e is a t op er a t i n g
te mperature the coolant le vel rises. I t falls
aga in when the system cools. If it falls
be low the COLD FILL mark when the
system is cold, top up to the mark.
Top up a ntifreeze. If no antifreeze is
av ailable, top up with cle an tap wate r.
If tap water is unavailab le, distilled water
can b e used.
After topping up with drink ing water or
dis tilled w ater, c he ck the antifre eze le vel
and a dd antifree ze if re quired. Have the
caus e of the coolant loss rectifie d by a
workshop.
Too low a coolant le ve l can caus e e ngine

To close , pos ition the cap and s crew it into

Brake and clutch fluid le ve l
The fluid lev el in the containe r must be
neither higher than the MAX mark nor

clutch fluid can lead to function problems
in the braking s ys te m.
After corre cting the brak e/clutch fluid lev el,
have the cause of brake/clutch fluid loss

9 Warning
Brake /clutch fluid is poisonous and
corrosive . Do not allow it to c ontact e yes,

more economic if these operations are
pe rforme d as part of a sc he duled se rvice
than having them performe d s eparate ly.
