Have Changed water pump, power steering pump, tensioner, ac compressor, alternator,belt, idler pulley, and belt still makes constant squealing and sometimes chirping sound

And putting soap on belt quiets it for about 15 min

Did you use a cheap belt? I have seen the cheaper belts do this. Go with a higher quality belt like Gates.

Is the compressor new? If not, I've heard A/C compressor pulley bearings chirp. Ditto for tensioner pulley bearings, which are easy to simply press out and press in a new "6203" bearing.

A/C compressor is new and so is the tensioner.

The compressor and everytning on the belt side of the car is new.

Thanks for your time.

Did you use a Motorcraft, Dayco, or Gates serpentine belt?
