Oh Gurus of N*s
My 1994 4.6L N* engine overheats after running 60-65 mph with the a/c on for 8 or so miles. It seems to do ok if I do local driving at 40-50mph with the a/c on the coolant temp stays around 225-240. I have 50/50 antifreeze in it. I have lubed and worked in the belt tensioner for the water pump. Any ideas would be greatly appreciated.
