I replaced the belts and a new water pump cause water pump was sqeeling, but new one is doing same thing and belt is tightened to specs . Using stethascope , the noise is def coming from water pump.
Belt sqeels after replacing belt and water pump on 2003 Kia Spectra
Check the tension on the belt and make sure it's not too tight and putting strain on the new pump pulley. Twist the belt to check tension.
