Just a bit of info. Start the engine and let it idle till it comes up to NORMAL temperature. With the hood open, cover the grille area with a blanket and let the egine idle. Listen to the FAN SPEED. When the temperature starts to rise, see if the fan starts to roar, if it does you can eliminate the clutch fan, if the fan speed does not roar(pick up speed) go get you an AC DELCO FAN CLUTCH. There is a two(2) letter code stamped on the clutch it's self, make sure you replace with same code. If all of this checks good, go buy a NEW radiator. I'm telling you this from experience, take it or leave it. Good luck.
