13.6) Feasible position and location of the oil cooler
See illustration 29.
➪ On principle the oil cooler T has to installed below the engine. See Illustration 29.
■ ATTENTION: If this position is not be practicable, install with connections upwards
i.e. in positive direction on z-axis. See Illustration. This will prevent an
unintentional draining of the oil cooler at longer engine stop.
▲ WARNING: The oil cooler has to be planned and installed such that the specified
operating temperatures are maintained and the max. values are
neither exceeded nor fall below.
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.
13.7) General notes on oil cooler
BOMBARDIER-ROTAX offers for this engine a non-certified oil cooler (see spare
parts list).
▲ WARNING: Certification of this cooler to the latest requirements such as FAR or
JAR has to be conducted by the aircraft builder.
■ ATTENTION: The oil cooler has to be designed to dissipate approx. 9 kW
(8,5 BTU/s) heat energy at take-off power.
◆ NOTE: From years of experience we recommend an oil cooler size of at least
160 cm
2
(25 in
2
), provided that air flow is adequate.
13.8) Filling capacity
