It would be very easy to lose a body part since you are messing around with spinning pulleys and belts. Not to mention getting the stethoscope hung up and having it slap you upside the head or shot across the garage/driveway like a bullet.

If it is the tensioner, or pretty much anything else, you can get them at the nearest auto parts store. As for tools, you usually don't need anything special EXCEPT for a serpentine belt tool.
agreed and it can happen to stangs with only 6K miles on them too....mine was the idler pulley.....didn't start until after the install of the S/C

what pulley are you guys referring to as the idler pulley. Are you talking about the extra pulley added with the supercharger that connects to my alternator? Or are you talking about the extra pulley just above the a/c compressor to complete the serpentine?

The idler pulley will be the stationary one on the front of the engine that isn't attached to any accessory. It doesn't run anything. Just bolted to the front of the engine. Probably the extra pulley you are talking about.

I was thinking it might be my lashers also, just trying to think of all the possibilities. The has 85,000 miles though and I've run Royal Purple 5W20 in it ever since I got the car with 15,000 on it. I've changed the oil and filter every 5,000 miles religiously. The procharger went on the car at about 60,000 miles and the chirp started at about 80,000 miles.

I don't think it's my lashers though because the chirping is much louder from underneath the car as opposed to being above it. That's why I was thinking it might have been my a/c compressor clutch, but my ilder pulley is directly above that and with the direct load increase beneath it, it could be the reason as to why my idler pulley is chirping.

I think I might be leaning towards the ilder pulley though because one of the mounting points for the procharger bracket is the bolt for the idler pulley.

Anybody else have any ideas or come across this issue?

If it's the idler pulley, you can get a new one from any auto parts store for not a lot of money. They are usually pretty easy to change but I'm not sure about yours because of the supercharger. If you do change it, you might want to think about putting on a new serpentine belt since you will have to take it off anyway.

Default Squeak when cold

I too have devolped a squeak. I have replaced the belt, the tensioner and pulley, all the idler pulleys, I have a magnacharger on mine so I even replaced the idler that is added in that kit, and finally the alternator. Still there! ****. HELP? Could it be the cupercharger? I have about 30K on the unit and 40K on the car itself.

I got rid of my bird by changing the tensioner pulley and the belt (Dayco). But now I can hear a soft whirring metallic sound in the idler pulley. When I tried to remove the bolt on that one, I couldn't get it to budge - now I am afraid to try - I don't want to break it off. I have been turning CCW (2006 V6 4.0) because I figured the bolt has to be unbolted the reverse of the pulley rotation. I have PB Blaster coming today so I can soak it and try again, but anyone have any suggestions other than that? Is it worth it. I have never used the stuff - do I need to spray in front and behind the bolt?

I am a new DIY mechanic and don't think I am capable of getting a broken bolt out of whatever this is bolted to......(also I am a woman :-) , so I may be thinking I am putting too much pressure when it isn't really enough - I thought the tensioner was frozen in place until I got a long enough breaker bar). Just a little timid - want to make sure I don't make anything worse.

Thanks!

Considering your RPM drop the A/C compressor is a safe bet. If the bearings in the pulley are going bad the engine may not be properly compensating for the extra load put on it when the compressor is engaged.
