88 formula V-6, auto. Replaced the water pump, replaced thermostat (tested good), fan works as it should, new aluminum radiator installed by PO, repaired the crushed coolant tubes. I have no leaks whatsoever. If I go on cruise around town it overheats, coolant blows out the radiator cap. I'm not 100% sure the PO installed the radiator correctly. The radiator cap hits the hood when closed, could this be the problem. It looks like a 3 row radiator and i'm not sure they shaved down the lower rubber supports. The top of the radiator is pretty snug in the brackets. Engine runs very strong and no white smoke out the tailpipes so I don't think headgaskets could be it. Kinda stumped on this one.
