Belt flapping help
Did a search and I couldn't find my particular issue. Looking for some opinions! I just replaced my water pump and serpentine belt and the new belt is flapping pretty good between the alternator and p/s pulleys. Flaps enough to make this annoying groan but only at idle. So, thinking it was the tensioner, I replaced it and it is still flapping. The belt is a gatorback and is the correct one.
So does anyone have any ideas? Idler pulley? Try a different belt? Any help would be great cuz it's highly annoying and I don't want to throw the belt.
