WARNING!

The cooling system is pressurized when the
engine is warm. When opening the expansion
tank, wear gloves and other appropriate
protection, embrace the cap using a cloth, and
open carefully to save arrangement pressure
slowly.

Annotation:

Cooling system is under pressure when engine
is warm. If necessary reduce force per unit area before
repair.
Secure all hose connections using product-
type clamps parts itemize.

VAG1921 pliers are recommended for installing
spring clips.
Ever supercede gaskets, seals and O-rings.
Arrows on coolant lines and hoses must
align.

them will crusade astringent engine damage. Part numbers are for reference only. Always check with your Parts
department for the latest data. If the fluid in the expansion tank is dark-brown, G012 A8 D has been mixed
with other coolant. In this case, affluent cooling system and modify
coolant. To flush, fill cooling organization with articulate h2o and run engine
for approx. 2 minutes. Flushing the system should remove most of the

Note (connected from page Page 19
-half dozen ):

G 011 A8 C or G 012 A8 D and coolant
additives marked with "according to TL VW
774C" or "co-ordinate to TL VW 774 D", prevent
frost and corrosion damage every bit well as calcium
deposits. They also raise the humid point.
Therefore, cooling organisation must be filled year-
round with frost and corrosion protection
additives.
A higher boiling indicate improves engine reliability
under heavy load, particularly in countries with
tropical climates.
Frost protection additives must protect confronting
frost to about -25 C (-thirteen F) and to about -35
C (-31 F) in arctic climates.

The coolant concentration must not be reduced
by adding water even in warmer seasons and in
warmer countries. The anti-freeze ratio must be
at to the lowest degree 40%.
If for climatic reasons greater frost protection is
required, the amount of Grand 011 A8 C or G 012
A8 D can be increased, but only upwardly to 60% to
obtain frost protection to well-nigh -40 C (-40 F).
Otherwise frost protection and cooling
effectiveness volition exist reduced.
