question on 2005 pathfinder

bmfgsxr · #1 (**permalink**) 02-18-2008, 02:50 PM

we recently bought a 2005 pathfinder and at first we didnt really pay attention to it, but the radiator fan runs constantly, and its actually very loud. we were quite happy with the car initially, and still love it, but its very loud to drive around with that you have to keep the stereo quite high to hear it. i know a belt driven fan is going to be louder, but i dont see why it would run constantly. there should be some sort of a clutch or something to that effect that would allow it to run when needed and not constantly. anyone have any idea about this situation? any help would be appreciated.

Hmm, it does run all the time, but there is also an electric fan to back up the A/C , make sure it is NOT running all the time ... I have an '06 and I have never noticed any fan noise .... sounds like you have a bad fan clutch ( they use a viscous fluid that thickens when warmed to engage the fan as the vehicle warms ) .... But you really shouldnt ever hear it ..mabie on first start up , but after that it should not be noticeable ....

thanks for the help.. we are bringing it into the dealer again tonight to have it checked.. they changed the tensioner first thinking that was the problem. but it wasnt.
