Paddy,
Oil thermostats are available from Mocal that might help. You have the use
the heavy duty with a 190deg F thermostat.
Hope that helps!

Subject: Europa-List: 912s Temps
Hi All,
I have an XS with a Rotax 912s and have been following the
discussion of 914 temperatures with interest, as I have the opposite
problem. In winter in the U.K. the cooling seems to be too efficient is the
cruise, so I have been experimenting with blanking off the coolers. My rotax
Operators manual gives the normal operating oil temp as between 90 & 110 deg
C., so a target to aim at would seem to be 100 deg C.. No normal operating
C.H.T.s are given - would 100 deg C. seem good for these as well?
Trying to get up to these temps requires blocking off more
than half the coolers, and this then reduces the operating time on the
ground and on the climb before the temperatures rise uncomfortably high,
even on the coldest days. In view of this compromise, has anyone got any
advice as to what minimum oil temp and C.H.Ts it would be advisable to use
in the cruise? I have seen the oil temp down to 65 deg C. on a very cold
day. Would it be wise to occasionally go to climb power, to try to raise the
temp, or would this cycling just cause extra stress on the engine? Or would
it help to fly faster ( or slower ! ) to try to increase the temps?.
Ideally it would be best to have a manually operated door to
cut the air flow through the coolers in cruise. Has anyone out there
developed something like this for the XS ? - I know it's been done for the
classic.
All advice would be gratefully received,
Cheers, Paddy Clarke
