The expansion tank (1) is located at the top of the engine. It has a
overpressure valve and breather valve which lead to the overflow bottle (4).
The coolant level in the expansion tank has to be checked with every Daily
Inspection and refilled up to max. amount (up to top of tank) if necessary.

the radiator (2) is located at the bottom of the central steel tube framework.
It is supplied with ram air through the lower center NACA cooling inlet.
3. !! " : !
The filling hole (3) for the expansion tank (1) is located on top of the
expansion tank (1). It is covered with a lid which closes the hole in a
pressure resistant manner. This is where the cooling system is filled and
refilled if necessary.
4. (2 ! 8 . !
The overflow bottle (4) is located at the left side behind the engine, near the
rear engine suspension. It is designed as a fluid buffer when the coolant
expands. The coolant level at the overflow bottle (4) is checked before
every flight. If necessary, refill coolant until coolant level at overflow bottle is
between ”min.“ and ”max.“ again.
