Hello everyone this is my first post since I've joined! So my first questions is about a chirp that I deal with every morning, i have an 04 Acura TSX. I replaced the power steering pump, serpentine belt and tensioner pulley a couple months back and a couple weeks back it started chirping when I started it in the morning. It chirps for about a minute or two then goes away. I thought it was a bad tensioner pulley and serpentine belt that I got when I replaced them, so I went and replaced them again and still the same chirp in the morning. Could it be another pulley or something else?

 

It could be a pulley on the PS pump, Alt, idler pulley, etc. Easiest way to diagnose is to remove serpentine belt and turn each pulley by hand. Feeling for a rough or sticky spot in the rotation. That would indicate a bad part if it's fairly significant.
You could also try starting it, when cold (typically when it happens, right), but without the serpentine belt. Does it happen then? If not, it's definitely the belt or an accessory or accessory pulley.

 

Try spraying the serpentine belt w/ water spray. If noise temporarily stops, the belt or misaligned pulley is likely issue.

See youtube video by chrisfix on this subject for help.

good luck
