Coolant Recommendations
When refilling the coolant system only use G 12 VW engine coolant. The frost and corrosion protection
additive G 11 must only be used for topping off purposes, when the cooling system is still filled with G 11
(green in color). On no account must G 12 be mixed with other coolant additives!
If the cooling system was filled with G 11 anti-freeze (colored green), before filling with new anti-freeze G
12 (colored red), the cooling system must be flushed out. Remove as much of the coolant remains as is
ossible from the cooling system. To do this blow compressed air into the coolant expansion tank. Close
cooling system and top off with pure water.
G 12 (G 11) and coolant additives marked "In accordance with TL VW 774 D (C)" prevent frost and
corrosion damage, scaling and also raise boiling point of the coolant. For this reason the system must be
filled all year round with frost and corrosion protection additives. Because of its high boiling point, the
coolant improves engine reliability under heavy loads, particularly in countries with tropical climates.
Protection against frost must be assured to about -25°C (in arctic climatic countries to about -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 greater frost protection is
required, the amount of G 12 can be increased, but only up to 60% (frost protection to about -40°C),
otherwise frost protection is reduced again and cooling effectiveness is also reduced.

(1)
Total coolant quantity may vary depending on vehicle equipment. Open bleeder
screw in coolant hose to heater core when filling cooling system.
(2)
Coolant fan thermal switch is located in the right side of the radiator.
(3)
Run after cooling fan thermal switch is located on the left side of the cylinder
head, between the injectors.
(4)
Thermostat is located on left side of engine block, under lower radiator hose
connection housing.
CAUTION: If the fluid in expansion tank is brown, G 12 has been mixed with other
coolant. In this case the coolant must be changed.
CAUTION: On no account must the coolant additives G 11 and G 12 be mixed. If these
additives are mixed it will cause serious engine damage.
NOTE: If radiator, heat exchanger, cylinder head or cylinder head gasket has been
replaced, do not reuse old coolant.
