thanks for the info. I did not lose much fluid when the radiator neck broke. No squealing until after radiator replaced. I just noticed the clamp became loose for no good reason. I asked the tech why a clamp would get loose and he said part of the neck likely was broken-he was right. I will drive and let the noise go away. We have a tech session in 2 weeks so I can replace the belt if still noisy and check tensioner.
