Cooling system, draining and filling
Note:
The cooling system is filled year round with a
mixture of water and anti-freeze and anti-
corrosion agent G 011 A8C.
G 011 A8C and coolant additives marked with
"conforming to TLVW 774 C" prevents freezing,
corrosion damage and scale formation, and
raises the coolant boiling point. For these
reasons the cooling system must always be
filled year-round with G 011 A8C anti-freeze
and anti-corrosion agent.
Due to its high boiling point, coolant is an aid to
operational efficiency when the engine is
operating at full load, particularly in tropical
climates.
Coolant must be drained and replaced if either
the radiator, heater core, cylinder head or
cylinder head gasket have been replaced.
Capacity: approx. 8.5 liters (9 qt.)

Cooling system leaks, checking
WARNING!
The cooling system is pressurized when the
engine is warm. Wear gloves and other
appropriate protection, and slowly and
carefully release system pressure, if
necessary, before performing repairs.
Engine must be at operating temperature
If the pressure drops: - Connect cooling system tester VW 1274 to expansion tank using
adapter VW 1274/1.
- Operate hand pump on tester to create a pressure of approx. 1 bar (15
psi).
- Locate and repair leak in the cooling system.
