I have a 2000 3.8l mustang and it now has 126,000 miles on it. Recently, since it has gotten cold around here, it has started making a bad squeeking/grinding sound when i crank it up in the morning or after it has been sitting all day while i'm ay work. It usually goes away after a few minutes and so I went and got belt dressing and sparayed it on the belt quite a few times but that never really made any difference. The noise sounds like it might be coming just a little farther back from the belt on the bottom left side of the motor. Any ideas on how i get rid of this horrible noise? |

bottom left might be the starter but that would only do it when it was first being started not while running. If it around the belt area just down low on the belt drive or back in the motor a bit.

you can put some water on the belt and if it goes away its the belt if it doesnt its the bearings on the pulleys hopefully. When you put new one on make SURE you tq them correctly to factory specs.

hey spector, i just had both bearings we were talking about in the thread along with my belt replaced, but its still squealing... do you think it could be from the belt being loose because its new? or the cold weather having something to do with it??? |

we have been having the same problem with our 2003 V6 Mustang.. I have replaced the idler bearing twice, the tension pulley once and now I just replaced the water pump. It's not the weather, we live in Florida and it did it in the heat of the summer and the cool days here in Tallahassee, when it really gets loud it will at times sound like its binding and you can feel the car shake a bit and it will stall, this has happened while stopped or driving at slow speeds...........oh yea also replace the belt all this has been done in the last 60 days........... any one have a idea?

take the belt off and spin the pulleys look for any grinding/rubbing places as well. See if you can rule out any pulley. You can also crank the car with no belt on (just for a couple seconds) to see if the crank pulley/balancer is causing the problem. Just make sure you be careful if you do that and do it at your own risk.
Other than that if you can rule out any of the pulleys then I would start to look at other things. See if you can narrow down the sound to the front of back of the engine.
