just an over the counter rad from an autoparts store. 2 core I believe. Looks like a 1/2 ton pickup D100 rad. I don't know if his 318 makes more power than the 360 4bbl. I do know the full time 4x4 and almost 5000 lbs works it going down the road, and the 13 mpg proved it ... LOL Doesn't matter, though. We've traveled in cars as well. He can solve the heating issue....
