Note
♦
Coolant additives may only be mixed with distilled water, as
the effectiveness of the coolant and the corrosion protection it
provides are greatly influenced by the quality of the water with
which the coolant is mixed. To ensure an adequate water
quality, the coolant additive should be mixed with distilled wa‐
ter.
♦
For approved coolant additives, refer to Electronic parts cata‐
logue (ETKA).
♦
G13 and G12++ may be mixed together.
♦
Coolant additives G13 and G12++ may be mixed with coolant
additives G11, G12 and G12+, though this may result in de‐
creased corrosion protection.
♦
G12 and G11 may NOT be mixed together.
♦
Do not reuse coolant.
♦
Only water/coolant additive may be used as lubricant for cool‐
ant hoses.

tries with an arctic climate to -36 ℃); note specification in
Maintenance table.
• The proportion of coolant additive must not exceed 55 %
(gives anti-freeze protection down to -48 °C); beyond this con‐
