About six months ago my water pump wnet out. So i replaced it with no problem, but i replaced the belt as well. Then it starting squealing. So after trouble shooting many different things (Idler pully, belt tension, etc.) It still was squeaking. So i replaced the belt again (from autozone) but it continued to squeal. So i did some reasearch and i read to get a belt from NAPA, That solved the problem for about 3 months, but i came back just the other day. I've tried everything. Could i get an expert opinion? Please help, thanks!
