Annoying Noise when A/C is on - Help
 

Hello,

I have a 2004 infiniti g35 and im getting a squeel everytime i turn the a/c on. If i do not turn on the a/c i have no squeel at all. I replaced the idler pulleys and assembly as well as added some underdrive pulleys, ie crankshaft, water & alternator pulleys. I just put on brand new belts of the appropriate size and tightened them. still get the squeel. Is it possible my a/c compressor is bad? I rotated the pulley on it with the belts off and heard no noise at all. Maybe I over tightened my crankshaft pulley? I have no clue, please help!

belt tension gauge.

Ugh, first thing I would do is get those pullies off there personally... They can definately cause more headaches than they are worth.
