Default Squeaking under hood.

My car has a squeaking noise coming from the belt system. I have changed the belt, the tensioner pulley, and the alternator was recently replaced. It's still has the chirping/squeak, does anyone know what this could be. It's the 4.3L L99.

Did you just change the tensioner pulley as stated or the tensioner? You need to change the tensioner.

You could have a fluid leak which is landing on the belt, causing it to slip a little. I believe there is also an idler pulley on the bottom next to the pulley on the crank.

Every time I had a belt squeak, it was solved with a GOODYEAR GATORBACK.
