Replaced my water pump so I decided to replace the fan clutch as well. The clutch that came with the car has a flat face toward the radiator with no coiled spring visible. It was almost frozen solid...couldn't turn the shaft once off the car and it was extremenly hard to manually turn when it was on the car with either a cold or hor engine. So I get a new cluth from GM Parts Direct. Shaft turns easily off the car...coiled spring facing radiator...turns about one and one-half turns on the car with hot or cold engine. The car had no overheat problem with the old clutch except in crawling traffic. Was the old clutch really bad? Can someone explain how the fan clutch operates? 67 327/350 no air.:confused
