I have a question for anyone that might have an idea to what could be causing my problem. My 03 c5z is making a sqeaking noise for a split second when I start to accel, then stops as my rpms continue to climb. Usually happens around 2000 rpm. Almost sounds like a belt slips for a second or can the alternator make a noise like that? Any ideas???
Could be the alternator, but for starters ... try some belt dressing and see if it stops.
'nother possibility is a weakened idler tension pulley ...
Since some have experienced throwing a belt on high rpm downshifts, the preferred OEM replacement is the LS2 tensioner, which has higher pulley sides ...

It is probably one of the tensioners. I had mine start going at 14,000 mls and it did squeak some times but I overlooked it. Then my belt let go and hit my hood, just ripped the liner. Dealer told me it was common and my old Z was an 03 also.
