– Unscrew cap -1- from expansion tank.
♦ Delivery inspection: Coolant level at max. marking.
♦ Inspection service: Coolant level between min. and max.
marking.
– If coolant is too low, add required amount according to mixture
ratio.
Note
Small quantities of coolant can be replenished. For larger quan‐
tities use the cooling system charge unit -VAS 6096- .
Note operating instructions for cooling system charge unit -VAS
6096- .
Note
♦
If fluid loss is greater than can be expected through normal
use, determine source and rectify (repair measure).
♦
Checking coolant level, replenish coolant if necessary
Note
♦
Coolant additive G12 Plus Plus prevents frost and corrosion
damage, scaling and also raises boiling point of coolant. For
these reasons, the cooling system must be filled all-year-
round with a frost and corrosion protection additive.
♦
Because of its high boiling point, the coolant improves engine
reliability under heavy loads, particularly in countries with trop‐
ical climates.
♦
The coolant concentration must not be reduced by adding wa‐
ter even in warmer seasons and in warmer countries. The
antifreeze portion must be at least 40%.
