I installed my new Vans oil cooler door and went for my first flight in my 6 with it yesterday. It was in the 30s and 24F at altitude. The oil temp got up to around 155F. I have the door in front of the cooler and the cooler is mounted to the back of my baffles. I had the door completely closed. I was not happy with the results. I'm looking for any fresh ideas on how to get my temps higher. Some fellow RVers suggest wrapping the entire cooler with some kind of insulation, thinking the outside of the unit is radiating heat. I also think the back side of the cooler being open to air rushing around behind the engine is part of the problem. I was thinking of totally block off the back side just to see what happens to the temps. Thanks in advance for any ideas.
