2007 Tahoe 5.3L V8 - ~~ 25K miles
I only drive it a few times a month - mostly used for vacation trips --
I started it up the other day using the remote start - it was COLD and raining
- 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?
