Engine cooling system
Rotax 912 UL cooling system
The Rotax 912 engine’s cylinders are aircooled, the cylinder heads watercooled. The cooling-air in-
take is located on the right-hand bottom part of the engine cover.
Cylinder heads are watercooled. The water pump forces water through the radiator, placed behind
the air intake opening on the top engine cover. The engine does not feature a thermostat valve. The
system is pressurised with a pressurised valve placed on one of the hoses. The overow tank uid
level must always be inside the designated limits!
The engine does not feature a cooling fan, therefore cooling is entirely dependant on moving air cur-
rents and airspeed.
CAUTION! You are strongly discouraged from leaving the engine running at idle power when
on ground.
The manufacturer recommends use of cooling uids used in car industry diluted in such a manner
that it withstands temperatures as low as - 20°C/-4°F.
