Filling 

NOTE:

Observe proper disposal regulations!

NOTE:

Only use coolant additive G 12 in accordance with TL VW 774 D. 
Identification: red colored.  

z

On no account must G 12 be mixed with other coolant additives!

RECOMMENDED COOLANT MIXTURE RATIOS 

z

Close drain plug for coolant.  

z

Fill with coolant up to MAX. mark on expansion tank. 

z

If the fluid in expansion tank is brown, G 12 has been mixed with other 
coolant. In this case the coolant must be changed.  

z

G 12 and coolant additives marked "In accordance with TL VW 774 D" 
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.  

z

Particularly in countries with tropical climates, the coolant due to the 
higher boiling point improves engine reliability when heavily loaded.  

z

Protected against frost to about -25° C (in arctic climatic countries to 
about -35° C).  

z

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%.  

z

Use clean drinking water when mixing the coolant.  

z

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.  

z

If radiator, heat exchanger, cylinder head or cylinder head gasket is 
replaced, do not reuse old coolant.
