For those of you with the hayden fan, do you feel that it is engaged at all during normal operation or spinning freely? Immediately after installing it I could feel and hear the difference at the front of the engine, acceleration seemed more dogged and it was definately louder. In fact, I installed it at the same time we replaced the OEM thermostat, and as were were running the engine to warm it up and top off the coolant, you could hear the fan kick in before the gauge needle even got to it's "11:30" ideal temperature reading. My other question is that according to the Hayden website, their clutches are supposed to engage at 170, but our thermostat is set for 180-something, correct? Doesn't it make sense then that the fan should be engaged at all times once the engine is warmed up? I'm just trying to make sense of why the hayden clutch had such an immediate and significant effect on my engine efficiency/mileage when it doesn't seem to be a factor for others.
Since nobody else is answering this question, I'll chime in: It sounds like, perhaps, you have a faulty clutch. It should not kick on that soon, and if it does, it should fade out. If you have a "gale force wind" noise all the time, i.e. you can hear the fan at all temperatures, all the time, that is NOT normal operation. I suspect that you got a faulty part. It happens from time to time, but should be warrantied. Good luck.
