Fan Clutch ???? AAAAGGGHHH!
99 chevy 4.3L s-10
Several weeks ago my stock fan clutch began to fail. The fan got louder and louder and eventualy completely jammed up. My truck sounded like a jet taking off. I tried to go the electric fan route, but I could not find fans powerful enough to keep the engine cool - I didn't want to pay the $400 to $500 for a custom fit shroud & fan combo. So I purchased a replacement fan clutch. Once installed I cranked the truck and again the engine sounded like a jet. I assumed either the part was faulty or not the correct one. I returned the clutch for another. The second clutch worked for about ten minutes in the morning and then jammed up. Every once in a while it would dissengage and quiet down - with NO relation to the engine temp. I got a third clutch and it worked like the second. I got a fourth clutch and it didn't work at all.
I then went to a different auto store and got a different brand. The new clutch does not work either. What the hell is going on here? What am I missing? I have had many cars and trucks with fan clutches, and all of them have eventually needed to be replaced . I have never run into this problem.
Any input from chevy guys?
P.S I picked up an electric fan and shroud from a 94 3.8L Taurus. The dimensions should almost perfectly fit my chevy radiator. hope it works
