Coolant

Maintenance – Fuels and lubricants
Copper containing materials (copper lines,
brass items) should be avoided, because they
can cause catalytic reactions in the fuel with
subsequent depositing in the injection system.
Always use a mixture of anti-freeze agent and
clean, dehardened water with a mixing ratio of
1:1.
Under particularly extreme temperature condi-
tions you should consult our customer service
concerning the anti-freeze agent to be used.
There are various types of anti-freeze agents
available. For this engine you should use eth-
ylene glycol.
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).
