Before filling in the coolant mixed with anti-
freeze agent the radiator must be flushed with
clean water. This procedure should be
repeated two to three times to clean the inside
of radiator and engine block.
NOTICE!
Danger of engine damage!
– Do not mix different coolants and
additives of any other kind.
Mixing the coolant:
n Prepare a mixture of 50% anti-freeze agent
and 50% low mineral, clean water.
n Stir well before filling it into the radiator.
n The method of mixing water and anti-freeze
depends on the brand of the anti-freeze
agent (see standard SAE J1034 and also
standard SAE J814c).
Add anti-freeze agent:
n If the coolant level drops because of evapo-
ration,only clean water is to be used for top-
ping up.
n In case of leakages you must always fill in
anti-freeze agents of the same brand and
the same mixing ratio.
Do not use any radiator cleaning agent after
the anti-freeze agent has been mixed in. The
anti-freeze agent also contains a corrosion pro-
tection agent. If this mixes with cleaning agent
it may cause the development of sludge, which
could damage the cooling system.
