i havent had any temp problems, and especially after I moved to Alabama. its Mid June, and we havent even seen 90 yet! You guys can keep the heat. If anyone does a radiator swap. ALUMINUM ONLY. Copper is outdated. aluminum dissipates heat much better than anything other than exotic metals. Some companies make 100% aluminum radiators too. I think Be Cool is one. There are also a few companies that make coolers with two fluids. ie tranny and oil. There are also spin on plates for where the oil filter goes for an in and out, and then your filter spins on its bottom like normal. Now let me see if I can get that GM crap radiator out of my Isuzu...
