Likely just the belt needs to be replaced - as engine bay warms - rubber belt becomes softer - more flexible..
Check Harmonic Balancer - Crankshaft Pulley may be superstition on it and See all Pulleys line up . good luck
Now - IF you meant *REPLACED* belt and tensioner and the chirping noise is occurring - return to installer for repair completion. Good luck!
