Cooling Fan Running all the Time
I recently had my fan clutch replaced and since then, the new one roars all the time, when the engine is cool or at highway speeds on a cool day. It did not roar at high speed before the switch, only when it really needed more cooling. The old one when working properly would roar on startup for a few seconds then shut down to a light spin, now it just stays at high speed spin. Could the new clutch be bad also, it does the cooling job, but I hate the noise all the time, and I can tell the power loss.

It is a none electric, mechanical clutch, no wires what so ever. I have taken a couple of short trips (150 miles each) with the replaced clutch and on the last leg of the second trip, the clutch finally quit running the fan as much at 60 MPH and I could notice the power increase. Once I got back into town though it was back to running all the time and it was only about 60 degrees out and had no reason to howl so much.

I am betting you did not put an OEM fan clutch back in due to cost. I ran into this problem with another truck years ago. I learned that aftermarket fan clutches don't work worth a sh*t. I tried several brands and they all either did not cool the engine like the factory one did or they roared (just like yours) like a son of a ... you get the idea. The only fix was to get an OEM one or to go to Efans.
If you did get OEM you ended up with a faulty one take it back.

I am guessing that most people would not notice that their vehicle is running hotter or that they suddenly have a loud roar because the fan clutch stays engaged all the time or way too long. Most people are clueless mechanically and accept whatever their mechanic tells them as gospel.
