when my 05 mustang gt has been sitting for more then a few hours and has completely cooled down and i start it there is a weird screeching sound that comes from under the engine. After its warmed up for a minute or 2 it goes away.

here are 2 videos of the sound, i just wanted to hear some possibilities to the problem before i paid to take it to a mechanic.

Without watching I would guess belt slipping.

It sounds like a bad clutch throw out bearing: http://www.youtube.com/watch?v=n-jWyrM71Ow

 

+1 on clutch throwout bearing

 

+2 on throwout bearing.

 

how much would it be to have the throw out bearing repaired?

 

I never had one replaced so I couldn't say how much. But I'm thinking the same: throwout bearing.

Also, those are some badazz pants, dude!

 

I think those were pajama bottoms...

 

Im gonna say throwout bearing as well, if your gonna replace the throwout bearing you mind as well replace your clutch. Usually when the throwout bearing goes bad it also indicates the clutch is gonna go soon as well and since to replace the bearing you have to remove the tranny anyway you mind as well do the clutch, just my .02 and my opinion

 

americanmuscle had one for around 350, and +1 about you might as well change you clutch, some say you also may need to change your fly wheel when you change your clutch i say just get it resurfaced
