Draining/Filling

CAUTION! Coolant/antifreeze must not be reused when replacing engine, cylinder head, cylinder head gasket. radiator and heater core.

Cooling system, draining

The cooling systems of all Volkswagen vehicles are filled at the factory wit 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 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.

Recommended Mixture:

- open cap on coolant expansion tank
- drain coolant through loosening either coolant hose l or 2



Cooling system, filling




- retighten loosened coolant hoses
- fill with coolant up to max marking on coolant expansion tank
- close coolant expansion tank
- let engine run until radiator fan comes on

- check coolant level. If necessary, top off up to the marking. With engine at operating temperature, coolant level should be at max mark. With the engine cold, the coolant level should be between the min and max marking.
