I just had a body lift done and it looks great. I have a couple of questions, though that refer to the engine. I had an oil leak coming from the aux oil cooler that they moved out of the way yesterday to put the lift on and I think it is fixed. But I hear the fan running now when I never used to hear it before. I mentioned it to them and they improved it some, but I still hear it. The temp here is pretty cold this time of the year and I don't think the motor needs the extra cooling. Is there some kind of adjustment for this fan, or is this the main cooling fan that I'm hearing? Regardless, is there a way to adjust this?
