| Open spring-type clip -arrow- and pull coolant hose off. |
Note Observe environmental regulations for disposal. |
Caution Only distilled water may be mixed with G12 plus-plus. The use of distilled water ensures optimum protection against corrosion. |
|
Note t
| In vehicles as of model year 2008, only G 12 plus-plus according to TL VW 774 G may be used as coolant additive. |
t
| For vehicles up to and including model year 2007 coolant additive G 12 plus according to TL VW 774 F and G 12 plus-plus according to TL VW 774 G can be used. |
t
| The coolant additive G 12 plus-plus can be mixed with the previous coolant additive G 12 plus. Identification: both are coloured purple. |
t
| Coolant additives marked conforming to „TL VW 774 G“ or conforming to „TL VW 774 F“ prevent frost and corrosion damage, scaling and also raise boiling point of coolant. Therefore, the cooling system must be filled all year round with coolant additive. |
t
| Because of its higher boiling point, the coolant improves engine reliability under heavy loads, particularly in countries with tropical climates. |
t
| Frost protection is required down to about -25°C (in countries with arctic climates: down to about -35°C). |
t
| The coolant concentration must not be reduced by adding distilled water even in the warm season or in hot countries. The coolant additive concentration must be at least 40%. |
t
| If a stronger anti-freeze mixture is necessary due to harsher weather conditions, the coolant additive content can be increased. But only to 60% (frost protection to approx. -40°C), otherwise frost protection and cooling effectiveness are reduced again. |
t
| If radiator, heat exchanger, cylinder head or cylinder head gasket is renewed, do not reuse old coolant. |
