It does appear to be constantly engaged and responds to the gas being pressed. I go faster, the fan blows faster and harder. I let off the gas, the fan slows down. Still sound like symptoms of a bad clutch?

Engine roar. I replaced the fan clutch, and my truck still has the problem. It is roaring all through the parking lots cuz I'm driving at low speed of course. But goes away as I accelerate. Any suggestions? Thank you guys.

Might want to look up how a clutch fan works.

Please start a clutch fan question in the H2 section after a search.

My '07 H3 was making a lot of relatively high pitched noise anytime the engine was providing power. Let off the accelerator and it got a lot quieter. Turned out to be a crack in the exhaust manifold - ouch! Can you say expensive repair part?

Did you ever figure this out?
06 H3 with 140K miles. When I accelerate from a stop, the engine roars, sounding like a semi truck. Also, when driving at highway speeds, if the engine downshifts to climb a hill or when passing another vehicle, the engine roars. Sometimes I am able to power through the sound and it will go away but that often requires that I stay hard on the gas and keep the RPM's over 3000. Other times, when attempting to power through the roaring sound, I will hear a hissing sound when the RPM's push 4-5000. Anyone had this problem, and how was it fixed. I'm not kidding when I say that the roaring sound is EXTREMELY LOUD, not to mention that my MPG's fall off significantly when this occurs. I've heard effort that it could be the engine fan, but with the fan disengaged, the roar continues.

Please AVOID digging up OLD threads to ask a question. This one is started nearly FIVE YEARS AGO. READ: Old Threads/'Necro-Bumping'
Same thing as what? We do not know what you are driving, miles, recent work, specific symptoms, etc...
When a clutch fan takes a puke, they engage often and not when they are supposed to. So yeah, we all figured it out........
Search first, if you still have questions or you can't find an answer, post up a NEW thread, include year and model, miles, recent work done, and symptoms.
