- and heard a slight chirp - sounded like a squeaky belt.
I say "slight" because if I am in the drivers seat I can not hear it -- after the engine runs for a while / drive a few miles it is quiet - no chirp even when I standing in front of the truck with the hood open.
I started the engine a few times now - hear the chirp - if I put a single drop of water on the serpentine belt (inside groves) the noise disappears instantly -
Should I replace the belt? It looks like new - no wear - no cracks.
Use "belt dressing" (I hate this ****)
Don't worry about it because it is normal?
I had a problem last year, and replaced the belt. and still got the chirp. Tried everything, yet it kept coming back. After searching the internet, it turns out that when I replaced the pulley on my power steering pump, I didn't tighten it down enough to get it in alignment. So that was what was causing it to chirp. Tightened it down and all is fine.
