Squealing noise on 2006 HHR
Hello. My wife's HHR is making a squealing noise. It's a 2006 LT with 2.4L engine and has slightly over 82,000 miles. It appears when engine has warmed up and is not really greatly affected by revving engine but will change slightly with increased RPM's. The noise appears to be coming from passenger side of engine so I have replaced alternator and belt tensioner assembly. Does not matter if AC is on or not, so that ruled out compressor bearing. I am going crazy trying to fix momma's baby. Thank you in advance for any suggestions/cures!
