Default Thermostat Issues

Alright guys, I was driving around today and i looked down at my gauges and the temp gauge was pegged, so i pulled over and shut her down popped the hood and about that time the overflow was spitting **** everywhere. Had one of my friends bring me some water and coolant started her back up and put all water into the backup tube, the temp went up and up at idle until it pegged again, so i check the backup tube and it was still all water so im thinking the thermostat just isnt opening up my engine for the coolant, so i had to get her home, which was only about 2 miles. On the way home i noticed that when i got my rpms up the thermostat would kick in, and i just replaced that thing, so any ideas?

when a motor gets that hot ... pouring water into the overflow isn't gonna get it. your lucky you didn't blow a head gasket or crack a head or worse. once you have run a motor real hot. it will never be the same again. when you shut off a motor that is hot the temp will rise another 20 to 30 degrees sometimes more. first of all you need to change the oil. look for any traces of a milky color. there is several things that could cause it to overheat. a water leak ( low on water ), fan not working, corroded radiator, faulty thermostat, bad water pump, and the above mentioned cracked head or head gasket. without being there it would be hard to diagnose overheating. sick

there are no damaging consequences that i'm aware of. sometimes in very extreme conditions it can cause overheating because the water doesn't stay in the radiator long enough to cool. but that's only in extreme cases. and in the winter it will take forever for your heater to warm. sick
