Not sure what this is, but you need to get this looked at very soon by a shop or someone that can diagnose this for you.
Overheating this engine is the number one reason for engine damage, so don't let it overheat!
it sounds like the heater core might be clogged-up. try flashing the entire sysem out or check the heater core physically by taken it out..
