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.
8.3.3 Coolant
Always use a mixture of anti-freeze agent and clean, dehardened
water with a mixing ratio of 1:1.
Under particularly extreme temperature conditions you should con-
sult 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 ethylene glycol.
Before filling in the coolant mixed with anti-freeze agent the radi-
ator 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 min-
eral, 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 evaporation,only clean
water is to be used for topping 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
protection agent. If this mixes with cleaning agent it may cause the
development of sludge, which could damage the cooling system.
