2.2.20. Filling-in of coolant
(only when engine has cooled down)
z
Fill in the coolant slowly.
z
Make sure that all air can escape from
the cooling system.
z
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.
WARNING :
If the cap with the working valves is opened, there is the rise that it will not close
tightly again afterwards. The excess pressure required in the system will then no
longer build up. Premature boiling occurs and coolant is lost. To prevent damage to
the engine, open this cap only in exceptional circumstances and fit a new one as
soon as possible afterwards.
