I've used one of the cheapy radiators, an auto zone clone. It worked fine until I smacked a tree with the rear of the truck, warped the upper tank and eventually split a seam. I'll have it fixed, of course, to have a spare. But, I'm going to have the shop work on my Mitsu radiator...thicker tank, visually stronger cores, larger fill cap.
