‒ → To drain coolant from engine also remove coolant hose from oil cooler -arrow-.
Note:
Observe disposal regulations!
Filling
Notes:
-
◆ Only use coolant additive G 12 in accordance with TL VW 774 F.
Distinguishing feature: coloured violet
-
◆ G 12 and coolant additives marked "In accordance with TL VW 774 F" prevent frost and corrosion damage, scaling and also raise boiling point of coolant. For this reason the system must be filled all year round with frost and corrosion protection additives.
-
◆ G 12 violet (in accordance with TL VW 774 F) can be mixed with the previous coolant additives G 11 and G 12 red!
-
◆ 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), as otherwise frost protection is reduced again and cooling effectiveness is also reduced.
-
◆ The refractometer T10007 is recommended for determining the current anti-freeze density.
-
◆ If radiator, heat exchanger, cylinder head or cylinder head gasket is replaced, do not reuse old coolant.

1) The amount of anti-freeze must not exceed 60 %; frost protection and cooling effect will decrease if amount of anti-freeze is too high.
2) The amounts of coolant given in table refer to vehicles with manual gearbox. For vehicles with automatic gearbox the amounts of G12 and water both increase by approx. 0.1 ltr.
-
‒ Secure lower coolant hose on connecting piece of radiator.
-
‒ Connect the coolant hose to oil cooler.
-
‒ Turn off heater control.
With cooling system charging unit VAS 6096
-
‒ Screw adapter V.A.G 1274/7 onto expansion tank.
