Squeaky belt after pulley install?

[Black_griffin6]

Not sure if this is any help or not, but it seems to only squeak when the engine gets hot. I'm thinking maybe it's the belt expanding with the heat?

I'm not sure...

The crank pulley was put on with an impact gun, the other 2 were with hand tools.
Everything sounds fine when I first start up the car, it's only after i've been driving it for a little bit and it gets hot that it starts to chirp and squeak.

That is odd. Usually the worst time for squeaking is when the car is cold and the alternator and power steering are drawing a lot of current.

In my case with my supercharger, backing out of the garage I immediately know it is time to tighten my belt, but once moving I never hear the squeak.

With yours doing it when hot, it may just be a poor quality belt that stretches too much when warm.
