Roger Lee Posted June 5, 2012 Report Share Posted June 5, 2012 I mounted a new 912ULS on a CT. During the first two flight the oil temps were 235F-245F. What's wrong????? Well I took the rubber skirt down under the radiator that was aimed back towards the engine and pulled it forward still in the cowl, but facing forward. The result was oil temps 20F cooler. Evidently the rearward facing rubber skirt allowed too much air to pass by where the forward scooping action of the skirt put more air across the radiator and not around it. Will this theory or idea hold up for other high oil temp owners? I don't know, but it's worth a try. It certainly worked for this engine. Link to comment Share on other sites More sharing options...
