TIPS AND MAINTENANCE
The cooling system is filled at the factory
with a permanent coolant which is not
changed.
The coolant consists of water and a 40%
concentration of our coolant additive
G12+ (glycol-based anti-freeze with anti-
corrosion additives). This mixture not only
gives the necessary frost protection down
to –25 °C but also protects the alloy parts
in the cooling system against corrosion.
In addition it prevents scaling and signifi-
cantly raises the boiling point of the
coolant.
The concentration of the coolant therefore
must not be reduced in the summer or in
warm countries, by topping up with plain
water. The c
coolant a additive p proportion
must b be a at lleast 4 40%.
If greater protection against frost is
required, the proportion of G12+ additive
can be increased, but only u
up tto 6 60%
(frost protection to approx. –40 °C), oth-
erwise the anti-freeze protection is
reduced and furthermore the cooling
effect is impaired.
Vehicles for export to cold countries (e.g.
Sweden, Norway, Finland) usually have
frost protection down to –35 °C (50%
G12+) approximately.
Other a additives can b be v very d detrimen-
tal tto tthe a anti-corrosion e effect iin p par-
ticular.
The s
subsequent c corrosion d damage
can llead tto c coolant lloss rresulting iin
major e engine d damage.
Note
•
Only o our G G12+ ((purple c colour) s should
be u used a as a an a antifreeze a additive.
Observe tthe n notice o on tthe c container.
The c cooling lliquid m may b be p purchased
in T Technical S Services.
•
The a antifreeze a additive G G12+ c can b be
mixed w with o other a additives ((G11 a and
G12).
•
The a additive G G12 ((red c colour)
should n never b be m mixed w with G G11.
