93 c1500 4.3l annoying belt squeak help.
 

Hello
I have got a 1993 c1500 wt 4.3l with 227k. I'm at my wits end getting good belt squeak to stop.
Replaced original tensioner with new gates belt, stopped for about 2 weeks. Went ahead and replaced the the idler pulley because it was grinding when i spun it. Again stopped for about a few days. So i checked the other pulleys found the alternator making some growling noise more than it should plus it's the original from 93. No luck.
The power steering is making a slight noise but no more than what should for its age. What am i missing? The alignment visually looks good. Still squeaks with ac on and off. Nor does turning the wheel make it more or less loud. Its a constant squeak with chirping rhythmically.
It seems like im missing something very simple. Could a worn water pump make it squeak?
Any help will be appreciated.

Are you sure the squeak is coming from the accessory area? A cracked flexplate can squeak as well.

Try squirting some water on it while it's running. If it stops it's the belt. I have replaced brand new belts because of squeaking... drove me nuts.

Nothing stops the squeak. Water, belt dressing etc. Haven't had the chance to go outside today to look at it. Been raining. Hoping tomorrow it stops. It'll stop squeaking when its at high rpms for a few min on the highway. Then omce i take off from odle it'll start again.

Water pump will make a noise sometimes when they go bad, kinda like a chirping noise.

Yep, check the water pump. I will link my old thread here: http://67-72chevytrucks.com/vboard/s...d.php?t=607963
