I was having some squealing and "jingling" type noise going on with my 2000 Z24. I replaced the alternator and it was still happening, so I replaced the tenioner pully. It doesn't seem to be making the "jingling" type noise anymore but it is sqealing nonstop and I think the AC compressor clutch has a bad bearing or something... I am wondering what this may cost to fix and if this sounds like the problem. Thanks!
