Unusual sound during cold start

Mga Sirs,
Ask ko lang input nyo. Ride is CRV 03 a/t. During cold start (morning) may unusual sound pag start/crank ng engine. High pitch na metallic ang tunog. Once naka start na, wala na yung sound. During cold start lang. Sa maghapon pag start ng engine wala naman.

Nag palit ng drive belt, ganun pa rin. Yung tensioner at alternator bearing last na palit at 3 years ago. Any input mga sirs.

Regards,
