2006 Grand Prix GXP. Problem (Thoughts) I bought a 06 Grand prix gxp.172,000 miles trans replaced Drove it over an hour home the next day went to work. Overheated found out the bottom radiator hose was leaking. Fixed that still getting hot replaced the thermostat still hot. Now coolant is boiling in the resevoir and steaming out the over flow! Head Gaskets?
