2013 was one of significant changes for our coach. We got a new engine, a new Manny Tranny with Power drive, installed a 3.21 diff, 1 ton, Manny brakes, and a bunch more. The engine failure made me nervous about reusing the oil cooler so I installed an aftermarket, standalone, fan forced oil cooler. It lives in front of the right front wheel well and exhausts down. It works great but I did notice it seemed to run a lot, specifically it would run for a few minutes after I shut down.
Today, I happened was doing something under the coach and the oil cooler was still running. I was near it and noticed an updraft. Humm, why is there an updraft? Upon investigation, I realized the blower was pulling up and blowing forward rather than pushing down and back. DUH!  
So running down the road the fan was pushing against the air flow resulting in less air going over the coils. I fixed that and expect it will be more efficient now. 
It has a 180° thermostat and I'm going to look for one that is about a little higher than the oil going to it in normal situations....probably 215° or so.
