Radiator Assembly, Thermo-switch





NOTE:
The cooling systems of all Volkswagen vehicles are filled at the factory with a mixture of water and an antifreeze solution (G 11) with corrosion inhibitors. This coolant mixture should be used year-round.

Phosphate-free anti-freeze prevents frost and corrosion damage, the formation of chalk and in addition, it raises the boiling point of water. Due to the higher boiling point the coolant is an aid to operational efficiency, when the engine is operating under full load, particularly in tropical climates.

When replacing coolant/antifreeze solution in all Volkswagen models, all model years, use phosphate- free coolant/antifreeze ZVW237 102.
