99 Chevy Squeal
I have a 99 Chevy Siverado 1500 4x4 with the 5.3. I changed the sepentine belt and now something is squealing. It gets louder as the enging rpms increase. I took the belt back off and checked the pulleys. The alt made some noise so I replaced it. It still makes a lot of noise and I am running out of ideas. I took the idler pulley off and that seems to be fine. I have sprayed wd-40 into the idler pulley and it seems to go away then comes right back. I think, if anything, I will replace the idler pulley and see where that leaves me.
Any help would be great.
