Overheating engine on '06?

Hi All:

I got in my GTO this morning, started her up, and sat for about 5 minutes waiting for the windows to de-ice (it was a cold morning < 32). After 5 minutes the windows were still icy and I noticed there was no hot air coming out of the air vents (I had the heat on full). I noticed the engine temp rise, and then the engine overheat warning came on...

I turned the car off, popped the hood, and noticed the engine fan was still on (key was out of ignition). I felt the engine and it wasn't really that warm. Got back in the car, started her up, and then reved the engine a few times. Engine temp came down to normal.

Any ideas? Any thoughts appreciated.

Thanks,

HSV.

I took it in to the dealer today to get them to have a look at it. They couldn't reproduce the problem (but the engine was warmed up). I'm going to leave it in overnight and see if they can reproduce it first thing on a cold morning.
