I've just replaced my 320 a2b with a 160hp 320 b2b and after 50 hrs I'm having the oil temp run at 230-235 :-? degrees on a 60 degree outside temp on cruise at 2400 rpm @ 5000 ft. I've put the oil cooler in the back and have the extention under the cowling for the STC from the Alaska and closed off the cowl hole with the winter cover as per the STC. I'd be in big trouble on an 80 degree day on a long climb out. I'm on floats but had the same problem on wheels. Any suggestions? Bob Long
