jfoust Posted June 6, 2007 Share Posted June 6, 2007 Hello everyone... I posted this on "that other site" and wanted to see if there are any other thoughts here. When I got in the Pathy to make a run to the store last night, I noticed a bad squeak has developed under the hood. I got home and checked my belts, and they all are in decent shape and I didn't have time to do much more than that. This morning I noticed that it was doing it again once the truck warmed up to operating temp. It only does it when it's idling, though; once I get on the gas it's quiet. So I made a note of that and when I went to lunch I noticed the exact same thing. So after doing a little reading, I went back out to see if I could turn it by hand and I can freely turn the fan as much as I want... I turned the engine on and looked at the fan and it does still run, but there's a awful noise. I have a feeling it's the clutch. If that's the case, while I drain the radiator and pull it, I'll probably do the timing belt/water pump/cam seals and just knock it all out at once, as I am on the verge of hitting 100,000mi any time now. I know some of you might think that if the water pump isn't acting up that I shouldn't mess with it, but I'd rather go ahead and do it while I'm in there instead of waiting for it to die on me and then going back to do the job! Thanks for any input on the fan noise you can give... -Jeff Link to comment Share on other sites More sharing options...
projekz Posted June 6, 2007 Share Posted June 6, 2007 (edited) I don't know about Pathfinders but I've seen fan clutches grenade on BMWs (I work for a dealership) and it's not pretty. I would do it if you're in there anyways...just for peace of mind! Edited June 6, 2007 by projekz Link to comment Share on other sites More sharing options...

I you've got the money for one, definately replace the water pump while you're in there. I didn't take that advice and it crapped out soon after, within 5k miles or so i think.

I know I've heard people saying don't do it if it's not broken, but I'd rather do it while I'm in there and try to save myself from ending up on the side of the road! Funny thing... On my way home from work today it must have been in the mid 90's and I didn't get the noise when I had gotten it last night, this morning and this afternoon, so I don't know what the deal here is. I might just do it all for peace of mind, seeing as how it is acting a little funny and needs to be done soon anyhow! Link to comment Share on other sites More sharing options...
88pathoffroad Posted June 7, 2007 Share Posted June 7, 2007 Check your harmonic balancer. They tend to separate at the rubber joint and squeak. Get underneath, grab that puppy and see if it moves in any direction. Link to comment Share on other sites More sharing options...

SaKaNa Posted June 7, 2007 Share Posted June 7, 2007 It probably is the harmonic balancer. I had the same thing, I thought it was a loose belt, because it was squeeking a bit, so I sprayed a TON of belt conditioner on all my belts, and suddenly the noise was completely unbearable. Turns out it was the harmonic balancer, and while I had that done, I also had all the drive belts changed. Link to comment Share on other sites More sharing options...

adamzan Posted June 9, 2007 Share Posted June 9, 2007 And if you wait too long it'll completly separate and you have a whole new mess on your hands Link to comment Share on other sites More sharing options...
