Screeching noise coming from belt area. just replaced powere steering pump & belt & this started.

The screeching is the belt slipping, two possibilities, either the belt is not tight enough, or you have fitted a faulty pump which is putting to much resistance on the belt? If it carries on screeching for any length of time it will break. Check your alternator belt tension, if you had to remove and refit that? Quick check for alternator belt is, switch on headlights, does the screech get louder? Don't over tighten the belts, this puts stress on bearings!

Could be a pulley, belt or bearings of sort. Take it to a well referenced repair shop for proper diagnostics.

I replaced the serpentine belt and now have a terrible screeching with the a/c is turned on.

A couple of things come to mind: if it wasn't screeching before replacing the belt, you may not have routed the belt properly - especially around the belt tensioner pulley; or the bearing on that pulley may need lubrication or replacement; or the A/C compressor bearing may have failed causing excessive resistance on the new belt resulting in screeching. Also, if the belt was not routed properly, the screeching may be coming from another belt-driven (power steering pump, water pump, etc.) but it doesn't sow up until you engage the A/C with its additional drag.

Screeching sound remains

Your AC pump is starting to faiL. It's starting to bind and putting heavy back pressure on the belt causing it slip and screech. After the car cools off inside, the load on the AC compressor is lower and the sound will die down. Also when the belt gets hot it gets a little more flexible and grippy which also lowers sound.

Take it to an auto AC repair place and have it checked.

99 olds intrigue power steering belt very hot, I just replaced the power steering pump, it's makes a clicking sound and is getting very hot, sounds like it could be the steering colume.

remove the drive belt and check each pulley by hand for drag, or noise. Usually noises from the serpentine belt area are from the tensioner pulley, but since you installed a new PS pump I'd pay particular attention to that-also, watch the belt and pulleys for any 'wobble' too.

I have 2003 Passat with 140K on the clock, 8 months ago it developed a screeching noise turning the wheel left and right when stationary like the belt was screeching. The garage could not see a problem,...

the screeching noise could be rubber deposits on the belt pulley or pulley bearings for the power steering pump BUT its also a big clue that the timing belt tensioner is about to give up...CHECK BOTH please.....

Engine noise

If it gets worse when turning the wheel at a stop, then it's the power steering pump. Could be the power steering fluid also. Check your belts for wear or damage. The idle pulley will make a constant noise, sometimes whining sometime screeching. To check idler pulley it is best to remove belts.
