DANGER!
If, in an exceptional case, the coolant
level has to be checked in an engine that
has reached operating temperature, first
carefully turn the cap (large cap) with safety
valve to the first stop, let off pressure, then
open carefully.
NOTE!
Do not open the cooling system when
the engine is at operating temperature. This
causes a pressure loss in the cooling system.
If the cooling system has been opened when
the engine is at operating temperature this can
lead to the alarm “pressure in the expansion
tank” when the engine is then put into operation
and to a reduction in the engine output.
Coolant pressure in the expansion tank is only
built up again when the engine has cooled
down.
The cooling system must therefore only be filled
up when the engine is cold.
!
WARNING!
When the cover is opened with working
valves, there is a danger that it is not
properly sealed when closed again. The
required overpressure is no longer set up in
the cooling system. Premature simmering
and loss of coolant result. To avoid damage
to the engine, this cover should as a general
rule only be opened in exceptional cases and
then replaced by a new one.
