Coolant, Draining And Filling: Filling

WARNING: This page is about a different car, the 2013 Volkswagen Beetle and 2012 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The water portion of the coolant influences the effectiveness of the coolant.

Volkswagen has decided to define the water quality used in the cooling system based on the different mixtures, countries and regional requirements.

For this reason, we recommend using distilled water for older models when adding coolant or filling the coolant for the first time.

Always use distilled water.

CAUTION: Only use distilled water for mixing with G12 plus-plus. Using distilled water provides optimum corrosion protection.

NOTE:

Only use G 12 plus-plus in accordance with TL VW 774 G as a coolant additive.

Coolant additive with the note "conforming to TL VW 774 G" prevent frost and corrosion damage, scaling and also raise boiling point of coolant. The cooling system must be filled with coolant additive year round.

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 down to approximately -25°C (-13°F) (in arctic climatic countries down to approximately -35°C (-31°F)).

The coolant concentration must not be reduced by adding water even in warmer seasons and in warmer countries. The coolant additive portion must be at least 40%.

If greater frost protection is required for climatic reasons, the amount of coolant additive can be increased, but only up to 60% (frost protection down to approximately -40°C (-40°F)), otherwise frost protection and cooling effectiveness will be reduced.

The refractometer T10007 is recommended for determining freeze protection density.

If the radiator, heater core, cylinder head or cylinder head gasket is replaced, do not reuse the old coolant.
