My car: 2004 Mustang, V-6, automatic; 95,000 miles. It just started squealing. I replaced the belt and idler pulley. Tensioner pulley felt good. Squeal is still there. Tomorrow I'm pulling the alternator for testing. Any other ideas or answers to similiar problems

Mine does the same, I was told it was an idler pulley... I haven't had it replaced but soon enough it should be... but I hope this doesn't happen to me now..

Is it throwing a code?
try checking out / replacing the camshaft synchronizer.

If you've changed your belt and idler pully you might want to check your water pump, power steering, and alternator, it could be a bad bearing.

it should be the idler pulley.

Yes, 99PEGASV6, It did throw up a code after squealing for two weeks, and it was a code for the camshaft positioning sensor circuit. I cleared the code and it hasn't come back in forty miles, so I thought it only happened once. I'm going to go out and buy one, now. Thanx, I hope that's it!

hopefully it is, quick and simple replacement too.

Well, I miss-diagnosed that noise a few times!! The noise got worse, I got out a metal pry bar out and started resting it in different places. When I rested it on the water pump it started vibrating in my hand and of course the noise was louder when I put my ear on the bar. Everywhere else it was silent! So I'm waiting for payday. I'll need a waterpump, a powersteering pump pulley puller and installation tool. I'm not sure about the 'hard line' in the top of the water pump. I think I can loosen it up and flex it out of there. Thanx for all the help.

I bought some belt dressing for my squealing noise... and well I might have put too much, but there's no more squealing... however now at idle, my car makes a hissing sound since i saturated the belt with the spray lol... is this ok?

Use a 7/8 end wrench for a pry tool, and lift up against the rim on the hard line. Comes right out.
