Same thing happened to me on a 94 Grand Am. Try changing the reservoir cap.
It could be a partially blocked heater core, a faulty heater valve that allows the coolant through the heater core or it could be a faulty water pump.
No. Just goto a shop have the coolant (antifreeze) changed every 2 years. Have it "REVERSE FLUSHED" and have the thermostat replaced at the same time (should only cost 80 bucks or so) A shop will know which stuff to put in. You will not be able to flush the system like a shop can. Its worth the money.
It sounds like you have a blown head gasket. Combustion gases can enter the cooling system through either a blown head gasket or cracked cylinder head. The gases (under pressure) force coolant out of the reservoir. This also causes a void in the upper part of the cooling system , leaving no coolant at the thermostat and the coolant temperature sending unit. The result is a erroneous temperature Reading and will even prevent the thermostat from opening.
1 gallon of antifreeze and 1 gallon of distilled water mixed 50/50 is sufficient to fill the system after it is drained and flushed. Or you can buy 2 gallons of premixed coolant. Be sure and replace the thermostat and bleed all air from the system. Make sure the heater control is set to HOT.

Hi there, if you have flushed any engine and have changed thermostate there are only two options that are left; (providing that there are no leaks) 1. the thermostat is faulty / 2. your water pump is broken and needs to be replaced
Maybe it is out of antifreeze? If older car, maybe you need the radiator and heater flushed.
It will contaminate the engine coolant and could change the properties of the antifreeze...you should have the cooling system flushed and refilled at a good repair shop...it is recommended by most car manufacturers that you have the cooling system flushed ever 2 years anyway.
Have you flushed the heater core?
Thermostat stuck open. Replace.
flush the system and change thermostat,this should fix problem. I flushed mine and i changed coolant and thermostat,it is now fine.
then you should have your radiator flushed because you have rust in it. FYI: antifreeze can strip the paint off of your it you spill it. Also, you may need to replace your radiator if the antifreeze is leaking, it may be through a rusted/corroded portion of the radiator.
