On my tracked Boss I put a 915 and 925 setrab oil coolers in front of the rad. The 925 above the bumper, and the 915 below, both in fresh air. The temp. delta is greater inbetween the Oil coolers and the ambient air temps then the Radiator and the incoming air....So is having the hotter oil coolers infront of the radiador making the rad much less efficient? Should the oil coolers really go behind the rad?
