1.4Description of the cooling system
The F30E engine has a mechanically operated forced fan cooling system. (Figure 1.4-1).
The F30E engine has the option of mechanically driven fan-ducted cooling fixed to the ignition side (Figure
1.4-1). The cooling fans are installed in the fan housing by eccentrics. They are driven by a poly flex belts
and a pulley that is fixed to the ignition system?s magnetic wheel. The cool air forced by the cooling fans is
distributed for optimal cooling of the cylinders by the air cowls that cover the two cylinders on each side of
the engine. The hot air from the cooling system is blown off to the underside of the engine.

The F30E engine is also run as a free-air engine. During installation it is important to ensure that the cooling
air produced by the propeller or free air provides adequate cooling to all cylinders. If this is not the case,
then air cowls providing correct cooling and suits the particular application must be fitted to the cylinder
heads
