Engine ticking/chirping? Help!
06 Base model 34k miles
I'm hearing a slow tick or clicking sound at the front of the engine. At idle its every 1-2,3 seconds. If I rev the engine it becomes constant or seems it.
I thought it was a loose accessory belt, but after looking at the engine, I see the belt tightener on the passenger side.
Oil level is good. What can it be? Thanks!

Whip the belt off and run it for a few seconds. If the chirp is gone you will know for sure it is belt/pulley related. If it's there still then it's something else. Takes five minutes.
Don't run it too long like this as the water pump/power steering etc won't be pumping.
I had a chirping noise which ended up being exhaust manifold gaskets. Bizarre?

And if that doesn't do it..
I find more use out of that tool. Worth every penny. It's amazing how well it works.

Marine Chevrolet in Jacksonville, NC fixed it. They had trouble all week finding an available harmonic balancer, but got it yesterday and fixed it this morning. Car runs great now. No chirping and you can definitely tell the balancer is "balanced" now. Cost $950. I'm happy with it, and nice to have my car back.

Just got back from the stealer with 2011 GS for the same issue. The service writer told me the chirp was my exhaust system, told me GM had issued a service bulletin on this. How do know if this is my balancer?

$950 for a balancer repair? Wow, I would be calling someone at GM to discuss that. This is a known problem, and was a recall issued for it on 2005 models. My car has the hood liner scuffed up from the belt coming off with the previous owner due to the balancer. If I had to pay for a repair I would be installing aftermarket balancer, and pinning the crank.
