Hi, i have a 1994 Jeep Wrangler and its squealing. It sounds to me like its coming from the serpentine belt. The belt is fairly new. Its squealing all the time, idle, stopped, driving 25, driving 55, it just constantly makes a squeal. I was thinking it would be a belt tensioner from what i read in other threads? Any helps appreciated.
Could also be a pulley. I would try and tighten up the belt first and if that doesn't work shoot a stream of wd40 into all the pulleys one at a time and see if the sound stops. If it still squeaked I would get some of that belt spray and see if that helps. Usually when my belt begins to make that sound I put a new belt on but since yours is already new that would be pointless.
It has a new water pump from previous owner in the last couple thousand miles (I forget exact just pretty recent). I'm pretty sure it's not the alternator. I personally don't think it sounds like that. I will tighten it and try the wd 40. If that doesn't work I'll look into the tensioner. Thanks.
Ok, today i tightened the belt and sprayed wd 40 on the pullies one at a time, it got a little quieter but then came back to normal sound. I then sprayed belt spray but that made the sound even worse. I think im going to change the tensioner. Will let you know what happens. Thanks.
It's most likely a bearing somewhere.
Try taking the belt off and turning all the pulleys by hand. The one that's stiff or gritty is probably the culprit.
Don't rule out the water pump. Just because it's new doesn't mean there isn't something wrong with it.
how much play is in the belt? it should only be about a 1/2" iirc...have to look into that again, there isn't an auto tensioner iirc...if its anything like the 4 cylinder in mine, u have to keep that in check, mine was at 3/4" of play and would squeal loud on startup for the first 5-10 seconds till i tightened it....
but if tightening it a lil more doesn't fix it, there's a bad bearing somewhere
Changed the one idler pulley (next to alternator), the other one was in metric so will change and replace tomorrow. The belt is also very tight. The noise got a little quoted sice I replaced the one. I have noticed that one the clutch is pushed in, the noise goes away. I'm thinking it could be a fan clutch? Will let you know after I put In new pulley tomorrow.
I put in the other new idler pulley and the sounds a little better but I really noticed that when I'm driving say 25 and take foot off the gas and push in the clutch the noise gets so quiet you can barely hear it. Take foot off and give it gas it comes back so I'm not to sure right now.
I checked the belt and it's about 1/2" play like the haynes manual said. And yea your out in Indiana, I'm right above Philadelphia in 19067. Thanks though.
well if i jumped in my brothers mustang, and only stopped 3 times for gas i bet i could make it there in about 7 hours.....might have a couple of states worth of cops on my tail...and a helicopter or 2...lol goodluck though
Well I bought it last tuesday for $3000. No rust or anything, but knew about squeal and figured it would be easy fix, it's not and now I need a new driveshaft. Thankfully I have a 2002 Toyota 4runner that never once gave me a problem.
