Prauch007 Posted August 23, 2005 Share Posted August 23, 2005 Recently my 2.5 engine on my 98 Legacy Outback has started a squeak. Seems to come from the drivers side of the engine and only at an idle. Hit the gas, no more squeak. Drive down a hill, back it comes. More annoying then anything. The belt looks good, was replaced last summer. Engine is running fine. Could this be a sign something is giving up the ghost? Pulley too loose? Any ideas?

drewd Posted August 23, 2005 Share Posted August 23, 2005 does it sound like a chirping cricket? bad idler pulley... Quote Link to comment Share on other sites More sharing options...
Prauch007 Posted August 24, 2005 Author Share Posted August 24, 2005 I guess I would say it was chirping cricket but now has turned into a constant squeal. Seems to be on the drivers side of the belt system. I cannot see a tension pulley on that side, just the compressor or alternator. I will have to look more. Thanks for the info. Wish some more engine diagrams and such were online for those of us without a Chilton's manual! Paul Quote Link to comment Share on other sites More sharing options...
Scottbaru Posted August 25, 2005 Share Posted August 25, 2005 If it's an accessory drive belt you can diagnose it by squirting a little water on the belt while it's sqeaking at idle, see if it changes. An old trick is dribbling soapy water on the belts if they've got a little oil on them. Quote Link to comment Share on other sites More sharing options...
wolfwrangler Posted August 25, 2005 Share Posted August 25, 2005 I have the same noise and only at idle, but I know what it is, I was just looking to see if anyone had any hints or tips of what to do to fix it. The squeak is coming from my Air Suction Valve. It's part of the Emissions and it uses the vacuum created by the exhaust to allow fresh air to be sucked through the air cleaner and into the exhaust to help burn HC and CO. I'm not sure if you have this on your yr./model but I thought it might be worth mentioning...and like yours it's running fine and the noise is more of an annoyance than anything else. I guess I'll delve into it when I get time. - Bill (mesa,az) Recently my 2.5 engine on my 98 Legacy Outback has started a squeak.

simbey1982 Posted August 25, 2005 Share Posted August 25, 2005 squeaks usually come from the belts or pulley system...check those out Cory Though more recently my squeak was my pistons metal on metal.....but thats only if you have no oil in your engine =0) Quote Link to comment Share on other sites More sharing options...
Prauch007 Posted August 25, 2005 Author Share Posted August 25, 2005 Yeah, the screach has turn pretty loud this morning. I am gonna call our one good Subaru place around here today. Problem is he takes all of September off. I just hope if it is a tension pulley, that it does not seize and then I am toast. Not sure, maybe somebody knows, if it is say, an accessory hose that runs say, just the A/C comressor, can the belt be removed till I can get the pulley replaced? Nor sure about the Air Suction Valve, but mine has def. changed to a squeal! Thanks for any advice. Paul Quote Link to comment Share on other sites More sharing options...
jimscat Posted August 27, 2005 Share Posted August 27, 2005 I just replaced my AC Compressor and both belts on my 93 legacy. after a few days I started to get a squeek then turned into a constant squeel. Check out tension on the belts. I had to drop a belt size after running out of adjustment)to get my ac belt to stop squeeling. Quote Link to comment Share on other sites More sharing options...
habib99 Posted September 18, 2005 Share Posted September 18, 2005 Is it definately coming from the front of the engine? Could be the pilot bearing in the flywheel but the sound would come from bell housing. Quote Link to comment Share on other sites More sharing options...
Olnick Posted September 18, 2005 Share Posted September 18, 2005 Last time I had an elusive belt squeal, turned out that the power steering pump had gone south on me. Any jekiness or notchiness in your steering? Quote Link to comment Share on other sites More sharing options...
gbrand Posted September 18, 2005 Share Posted September 18, 2005 On my legacy the noise turned out to be the idler pulley for I think the A/C belt. Pulled off, and let some oil dribble/soak in the cracks of the bearing while horizontal, made squeak disappear. Repeat every 50000 miles or so....

VorpalBunny Posted September 19, 2005 Share Posted September 19, 2005 Very good chance it is the idler pulley bearing. When the water pump is starting to go, it sometimes sounds like it is full of rocks or marbles. Quote Link to comment Share on other sites More sharing options...
Prauch007 Posted September 19, 2005 Author Share Posted September 19, 2005 After talking to my mechanic he was saying it could be the timing belt too. I guess I am bout due to change it with 95,000 miles on it! But he will be back in October and I have a list of problems for him! Minor oil leak, front bushings are worm and squeaky then this belt squeel! Will it never end! Thanks all! Paul Quote Link to comment Share on other sites More sharing options...
