2005 Kia Sorento

Noises problem
2005 Kia Sorento 4 cyl Two Wheel Drive Automatic 85,000 miles

I had the serpintine belt and the 2 other belts that are usually changed at the same time, the serpintine belt. Things were great for about 2 weeks no noise, seemed fine.
Today I started up my car and the A/C was on and there was a loud squicking noise again. I turned of the A/C and it wasn't so loud.
Any clue what this might be.

The AC belt needs to be readjusted. It may have stretched a little, just enough to make noise. If you check it, I bet you'll see that it's loose.

Let me know what you find.
