I recently changed my thermostat coolant hoses and added mew coolant to my 2k6 MC SS. I bled all the air out the system also. Today O was at a stop light and my temp gauge went 3/4 of the way. Next thing I here is a loud pop and coolant everywhere. I pushed it over to the side of thee road did some eyeballing and saw the lower coolant hose came off the radiator. I had just replaced them 3 days ago. Anyone have any advice of what I should do. Could it be the radiator or water pump. PLEASE HELP!
