i just installed a lightweight full size pulley and now there is a squealing when i run the car. i've checked and reset the belt several times and it feels as tight as it did before, except now there is a constant loud squeal.

what did i do wrong and how do I fix it?

I also noticed the lightweight pulley feels a lot hotter than any of the others is that just because it's aluminum?

thanks for any help, this is incredibly frustrating
