One other possibility is the o-rings that are on the plastic elbows that go from the belt tensioner assembly (yep coolant runs through that!) and the engine. If it's a slow leak you might not notice it because it will either run off or evaporate before you can see the problem. You might try taking it to a shop to have it pressure leak tested. Mine had 105K on it when it went bad. Every mechanic thought it was the manifold (I'm waiting for that to go bad too!)

I have an '02 Impala LS 3.8L and at 90,000 miles I had a similar problem. It turned out to be two plastic elbows between the Intake and the Plenum. I ran me about $360 to have them replaced.

 Hello everyone, new on here, so bare with me. Had a head gasket fail at 90,000 miles by number 1 cylinder in Jan, 2012. Purchased the car new with 7 miles in 04.Know its whole life history. It's had its share of check engine lights on under its warranty life, but had not been in the shop since 2007. It wasn't that bad of a job to replace both head, exchaust, lower and upper intake manifold gaskets. Had the heads plained, and pressure tested. Went with new head bolts. Also give me a chance to replace spark plugs. I was really surprised that the intake manifolds were sealed well with no leaks. Really had no reason for the failure, never overheated, but did find what looked like shipping material in block coolant port by number 1 cylinder. I'm posting this for informational purposes only and maybe can help someone down the road.

My 01 Impala - 3.4 had the well-know Head Gasket leak - repaired 80,000 miles (take a look at the gasket coming out ..... and the one going to replace it ! Quite a difference. ) This is a well publicized problem that can easily be confirmed by a mechanic checkup. I would recommend getting a number of quotes to replace/repair this......cost may be lower at your local mechanic vs. at the GM dealer --- shop rate in Canada is $110 per hour. Should be a 3-4 hour job.
My properly serviced Impala is at 160,000 miles and running strong......resisting trading for an 08 LTZ.
