Clutch fan replaced, now extreme roaring sound
I had the clutch fan replaced on my 2002 4.7l Dakota a year ago and as soon as I got into the truck to leave the dealer it started roaring like an 18-wheeler. Turns out it is whenever the clutch fan kicks in. I am scaring people in parking lots!
We bought the truck new, and in the previous six years it never, EVER once made that sound. The second I left the dealership after having the clutch fan replaced, it started. Any idea of what this could be? Local repair shop is trying to tell me it must not have been working before, but I could tell when the clutch fan would come on before and it would make appropriate sounds and kick back off accordingly.
The local shop found the electric fan needs replacing -- could the previous dealer have damaged/disconnected it somehow so it didn't work, thus making the clutch fan run harder to keep up, thus making the noise? Any thoughts?
