Hi boys & girls. I'm a 60 year old 1st time Vette owner. Its a beautiful 2005 blue attention getter. My question today is I have to add gnome coolant about every 150 miles. Don't smell anything or detect any leaks. Is this the nature of the LS2 engine? Help. JT
Welcome to the forum J.T. and congratulations on your find. You will probably have more luck with your specific question if you ask again in the C6 section: Here's the link.

Welcome! I agree that you have an issue in the coolant system - most likely a small leak somewhere or maybe even a leaking head gasket. Is the coolant reservoir cap tight? Good luck!
