Well...I was trying to figure out what this squealing noise was coming from on my John Deere 430 and I think its the belt that goes around the water pump and alternator. The pulley on the alternator turns freely so that's a sign that the belt is loose and is slipping. Does anyone know the part number for that belt and I'm hearing it's a tough job to replace. Is it also good to go ahead and replace the water pump to while everything is already torn down?
