Has anyone had problems with the 7.3 fan clutch staying partially engaged. Last couple of times I drove the truck, ECT was at 190 and I could hear the fan roaring & could feel the drag on the engine. I can turn the fan by hand, but definitely feel some resistance - I always thought the fan should spin freely when cold? Clutch is less than a year old, but was bought on rockauto, so might not be of the highest quality. Any suggestions other than replacement?
