So my wife's XT5 is needing a Engine Coolant Water Outlet (thermasat we call them) I looked up the part on the GM parts website, I think it was a little over $100.00. They are charging us a little over 200.00 total is $1014.00. I know this has been an issue with many of these. It has just over 60 thousand miles. I guess we are getting soaked?
