>I sure wish someone had a solution for the 914 overheating. I have
lowered
the oil cooler and moved it back one inch from the water radiator. The oil
runs cool(under200) so I put an air dam half way across the bottom of the
water radiator, the water is now cooler by about ten degrees and the oil is
warmer by ten degrees. In climb at 100 MPH but the oil and water get
hotter
than I like (230)so I level off and climb slower at 125MPH and things stay
under 230. On the ground, I can taxi around for about 10 minutes before
temps get high. Have not done cowl flaps yet. <
How many hours have you done on the engine? With the 912S at least the
temperatures eased down after about 20-30hours flying time. 230F is about
110C which is not too hot. During high power climbs whilst flight testing
we used 130C as the absolute limit. I believe the oil will take another 10C
on top of that without problems. This temp is also OK for the coolant
provided that you are using the recommended 80:20 ratio for glycol:water.
As an observation on a few 912S Europas it seems that the oil temp is the
limiting factor whilst running in with a Classic cowl, whereas the coolant
is more limiting on the XS. In the case of the Classic repositioning the
oil cooler below the prop with an inlet scoop was a great help. From
35hours onwards I now find it is a little on the cool side unless it is a
particularly hot day.
