Protection against frost must be assured to
approx. -25 C (in arctic climatic countries to
approx. -35 C).
The coolant concentration must not be reduced
by adding water even in warmer seasons and in
warmer countries. The anti-freeze ratio must be
at least 40%.
If for climatic reasons a higher frost protection is
required, the amount of G 12 can be increased,
but only up to 60% (frost protection to about -40
C), as otherwise frost protection is reduced
again and cooling effectiveness is also reduced.
Refractometer T10007 is recommended for
determining the current density of the anti-
freeze.
If radiator, heat exchanger, cylinder head or
cylinder head gasket are replaced, do not reuse
old coolant.
Recommended mixture ratios:
40% 3.7 l
50% 4.6 l
1)
The quantity of coolant can vary in accordance
with the equipment fitted to the vehicle.
2)
Only use clean drinking water.
