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.)

- Close drain plug at engine block and at bottom
left of radiator.
- Push on connection flange of coolant hose at
bottom of radiator, and install locking element for
connection flange.
- Unscrew cap on expansion tank, screw on adapter VAG 1274/1, and
extend with 42mm diameter and 100 mm long auxiliary hose.
- Open hose clamp, pull back coolant hose sufficiently so that vent hole
is no longer concealed by connection.
- Open bleed screw at coolant pipe below expansion tank.
- Pour coolant into system until it flows out at bleeder hole, then tighten
screw to 15 Nm (11 ft lb).
- Pour in more coolant until it flows out at vent hole, then push on
coolant hose and tighten.
- Close cap on expansion tank and set heater controls to hot position.
- Start engine and run at about 2000 RPM for about 3 minutes.
