yes sorry i did mean thermostat, i replaced the radiator [and thermostat]because i had the same prob last year and i thought the rad looked like it needed to be replaced and until we were coming back up the m1 we had not had aprob for 10 days driving it does not lose any water and there are no bubbles in the rad and as soon as it gets hot we pull over and the gauge goes straight back down so i do not no what else to try. thank you
