For proper operation of the cooling system the expansion tank (1) with pressure
cap (2)
has to remain for all possible engine positions on the highest point of the
cooling circuit.
▲
WARNING: The radiator has to be planned and installed such that the
specified operating temperatures are maintained and the max.
values are not exceeded.
This state has to be warranted for "hot day conditions" too!
If need be, take appropriate measures like changing size of
cooler, partial covering of cooler etc.
Additionally the system needs an overflow bottle (7) where surplus coolant is
collected and returned back into the circuit at the cooling down period.
