Fuel Filter: Renew - Volkswagen Golf Variant 2007 Maintenance Manual

4.24.3 Mixture ratio:
Caution
Only tap water may be used for mixing. Well water does not
have the required quality to ensure the effectiveness of cool‐
ant.
Frost protection to
-25 °C
-35 °C
-40 °C
1) Use clean tap water only.
Note
Coolant additive G 12+ and G 12++ prevents frost and corro‐
♦
sion 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 anti-
freeze portion must be at least 40 %.
