I have about 55 hours on my airplane now and still seem to get hotter oil temps than I prefer to see. I live in the East Bay Area, CA. and typically in the heat of summer we get 95-100 degree days. My oil temps are typically around 200 during normal cruise, but sometimes see up to 220 - 225 during hard climb take offs, high prop RPM, and when performing manuevers such as slow flight with higher loads on the engine.
My oil cooler is mounted behind cylinder #4 on the rear baffle, so I think the location is fine. I also feel my baffling is sealed up pretty good and getting good airflow.
I currently have the Van's $234 EA OIL COOLER II

and was thinking of replacing it with a Stewart Warner 8432R. I was hoping to get some feedback to see if the footprint was the same for an easy swap as well as would this be the best oil cooler for my application? Is there another oil cooler that may be even more effective than the 8432R and has about the same footprint, so that I can keep the same location? Van's website states that the oil cooler I have is a "Traditional Stewart Warner Style" but is the actual 8432R that much more effective? If I can get 10-15 degrees lower temps by replacing the oil cooler, I think I would be in the ballpark of where I would like to be.
