I have a 2001 Dodge Dakota with the 3.9 V6 and a 5 speed manual, 124,000 miles on it. Occaisonally the viscous fan clutch will make a roaring noise when the engine is cold, the noise is present for about the first 1/4 mile then clears up.
Today when I went on a 100 mile round trip I was about 10 miles from home and the roaring noise just appeared out of nowhere and the truck seemed to lose a fair amount of power. It wasn't overheating, oil pressure was fine too. When going uphill in 5th gear at 1500 RPM when I gave it gas the RPM and speed increased so I don't think it's the clutch.
At home the roaring noise is present with the truck sitting still in the garage when I operate the throttle manually. The fan was very hard to turn when I first got home and is still very hard to turn now, 3 hours later. I know if you spin the fan and it spins freely the fan clutch is bad. But I have also heard and read if the fan is really hard to move at all that is also a sign the fan clutch is bad. There is no movement or play at all in the water pump shaft, none that I can detect.
I think I have a bad fan clutch, and I appreciate any help you can offer. I can't really find a lot on the hard to turn fan symptom online.
Thanks for any help here.
