Is there any way to slide the ac compressor forward to check the mounting bolts on the accessory mounting bracket? I do not want to remove the ac lines. I have the chirping noise at idle only & no noise when I start engine with belt off. I have already tested the alternator, tensioner pulley, p/s pulley, crank pulley. Did not check crank sensor, but will after checking the accessory bracket bolts after putting everything back together. Any suggestions appreciated.
