Default SCREECHING noise

Just replaced my Serp. Belt - But the short "Screech" still happening - Belt noise is gone and this only happens when starting the car - Sounds like it's from right in front of the steering wheel - Any clues ? ANYBODY ?

did u check the tensioner and pulleys to see if they are in proper working order?

It feels good to be blown.

Check your harmonic balancer (crank pulley) and see if broken like in the pic.
