[QUOTE="RossKean, post: 1394469, member: 19880"] I assume that the radiator is really topped up - not just based upon what is visible in the expansion tank? If the line from the expansion tank is blocked or kinked, liquid won't go to or from the tank. If there is a hole or crack in that hose, liquid will go out of a hot radiator into the tank (with minimal leakage) but when the radiator cools, the liquid in the expansion tank won't suck back into the radiator. Same if the hose that goes to the bottom of the tank is missing, degraded or curled around so the open end of the hose is above the liquid level. Does anyone have any idea what is the opening temperature for the thermostat? [/QUOTE]
