2006 GTP coupe, 2007 SE sedan(c3y)
It’s -16 F out and I went to start my g6 and it made the most horrendous squeal sound I’ve ever heard. Que checking the belt and tensioner, belt is tight and I can still see the ink stickers. Started again, went away after a few seconds, went down the highway for a few still when in gear accelerating 2000rpm-max it makes belt squeal sounds, but will not in park or neutral. Coolant is dull orange and no pressure in surge tank hot. 127000mi. Any ideas, this is my only ride atm, and if somethings wrong I need to take time off night shift to get it into a shop, any help appreciated.
