Well I'm struggling how to mount this oil cooler. This is the last space I have to mount it. Right now the way it is sitting on the wood blocks it will draw fresh air and suck up through. But that fan is about 2 to 3 inches away from the bottom of the truck. So it is going to blow all that hot air against the bottom of the truck and past the battery and air pump for the bags. I also feel like I need to make a perforated screen in front of it to let air through but yet stop that tire from kicking road debris up and damaging the fins. The only other option is to flip this thing over and suck air down from that little hole. I don't see that cooling very well.
