5.4. Cooling
Fill the cooling system of the engine with a mixture of drinkable tap water and antifreeze agent
on ethylene glycol basis or anti-corrosion agent.
5.4.1. Filling-in of coolant
(only when engine has cooled down)
•
Fill in the coolant slowly.
•
Make sure that all air can escape from
the cooling system.
•
Run the engine briefly and then check
coolant level once more.
If, in an exceptional case, the coolant
level has to be checked when the engine
is warm from operation, first turn the
somewhat smaller cap with working
valves to the first notch. Let off pressure
and then close this cap again. After this
the cap on filler neck can be removed
without risk of scalding.
Coolant must be added at the filler neck
only. Do not put cold coolant into an
engine which is warm from operation. If
no hot water (80
˚
C) is available, add
normal warm water very slowly as the
engine runs until the coolant level is
correct.
Ensure that the ratio of water to
antifreeze is correct. Find the cause of
the loss of coolant and have it eliminated.
