Normally the coolant is blueish, I doubt that your coolant could contain some rust but put your finger in the leak and if it's quite like water but a bit more slippery, it's coolant.

looks more like brake fluid or transmission fluid. Is there a smell to it?

With the amount of o-rings typical to the late generation GM engines an oil leak is unlikely. In addition I agree with the above posters - photos can be deceiving but that does not look like oil. If it is oil, you have a larger problem with it being that color. :)
Has the oil recently been changed? Any service done? Top off any fluids?

No noise, I called the dealer and he said if it is redish color it may be coolent, I will be taking it to them tomorrow to drop it off so they look at it on Monday morning. They do not have high level mechanics on Saturdays. They will provide me a courtesy car.

Steve; We have had a few owners that had pin hole leaks in their radiators. Is there any wetness in the engine bay?

Steve, which dealership are you going to down there? Ask around here on the forum for recommendations if you don't already have a good idea, or a working relationship with a dealership. I know some SoCal people expressed extreme frustration with a few of the service departments down there.

I am going to Chevrolet of Irvine, it is the closest one to me. Normally I take it to Selman Chevrolet in Orange but my service guy is on vacation now and next week.

That's exactly what the coolant looked like on the floor when my radiator was cracked. Had an oily feel and red color.

do they stock these radiators or will I have to wait for them to order and install? I am trying to figure out how long this will take them to fix?

Irvine Chevy had a radiator brought in from another dealer and had Star repaired in two days. Made me wonder why a radiator was so available on a new car.
I think they got it from Selman.

Is this normal quality for American cars? I have a 2011 Toyota sienna van that my wife drives and it has never been at the dealer since new only for oil changes. I had a 2000 Sienna van that she drove for 11 years and no issues, never at a dealer for problems, I probably should have gone with my 1st car choice which was a Lexus LS460????

It's a Corvette, not a Civic.

The more power you pump into a given volume, the more stress you'll have on components, and problems will occur.

Don't sweat it - it's just a radiator.

That's why we have warranties, crap happens. I love my C7 so much it doesn't really matter what happens to her from a warranty aspect. She could blow a motor and I wouldn't question my purchase. I work for a major manufacturing facility in another industry and warranty is a fact of life. All manufacturers have it and expect it. Everything is a result of a sum of parts and the parts are from various vendors. We select the best vendors we can, and those still have fallout. Then we have to work with those vendors to get their issues fixed. That's why practically anything you buy from a car to a toaster has some sort of warranty from 30 days to a lifetime warranty, all manufacturers know there will be some number of failures.
