Oil Cooler
Depending on the aircraft and climatic conditions, an optional oil cooler will be necessary. A
complete oil cooler kit is available from ULPower.
The oil cooler can be connected on the interfaces of the sandwich plate with integrated thermostat
which is situated at the front left side of the engine. Unscrew oil filter (1) and oil filter screw (2).
Put the oil filter in a clean place so it can be reused - new oil filter is not provided with the oil
cooler kit.
The image below shows the items of the oil cooler kit and in what order they should be connected.
The integrated thermostat shut of the oil flow to the oil cooler until the oil temperature reach
± 80° C (176 F). This is necessary to warm up the engine quickly in winter time.
Connecting oil filter sandwich plate
Insert the male adaptor bits (3) together with a copper sealing ring (4) into the oil filter sandwich
plate with integrated thermostat (5) and gently tighten.
A torque of max. 25Nm should be sufficient to ensure
proper sealing.
Place the sandwich plate where you unscrewed the
filter; with the rubber seal facing towards the engine
casing.
Insert the oil filter adaptor screw (6) in engine casing
through the sandwich plate.
Rotate sandwich plate to desired position and tighten
screw with spanner (again a torque of max. 25Nm
should be sufficient).
Lubricate the oil seal of the filter a little and screw filter
onto the sandwich plate. The filter should only be
tightened by hand.
