'94 Voyager Overheating

Hi everyone. I hope there is someone out there who can help me. I initially noticed a problem when my heater stopped working. I checked the antifreeze/water level, and it was very low. I filled it back up, drove about 10 miles, and water started boiling out of the top. However, I can't find a leak anywhere - the engine just seems to be getting hot and boiling out all the water. The temp gauge is running a lot higher than normal, also. I have been told that it could be either the heating coil or the temperature regulator. Do these symptoms sound familiar to anyone? Thanks.

Replace the thermostat and your problem should be solved.
