Sometimes it is not actually "boiling", but bubbling. Start by getting a new radiator cap. It is the first thing you should do, and is easy. *MAKE SURE YOUR CAR IS NOT HOT WHEN REMOVING A RADIATOR CAP* When air enters the closed/pressurized cooling system, the air ends up in your reservoir tank and bubbles the top. !

Hey L==Either the engine coolant level is extemely low or the temp sending unit is incorrect. Make sure the radiator is full of coolantWHEN THE ENGINE IS COOL. If it still does it, have the temp gauge checked. GoodluckJoe
Tough to narrow it down with such little detail, but it sound like your car's thermostat may be malfunctioning and not controlling the temperature correctly.
if the coolant in the overflow rises and overspills when you shut the car off or is boiling in the reservoir
Higher pressure raises the boiling temperature of the coolant.
Sounds to me like you have a leaking head gasket. Take the car to a good mechanic and have him check it out.
The water and coolant is put in the coolant reservoir for the location of this refer to the owners manual. It is best to do this when the engine is cold otherwise you run the risk of getting boiling water all over you. the mixture of coolant to water should be about 50/50.
Yes, a mix of coolant and water typically has a higher boiling point than water alone. Coolant is designed to increase the boiling point of the mixture, providing better protection against overheating in the engine.
first thing to check would be the thermostat in the engine. next check the radiator cap. also check that radiator hoses are good, and not soft.if they are soft they can colapse when hot, stopping the coolant from circulating check to see if there is coolant in the oil that would indicate a blown head gasket.
Radiators are typically filled with a mixture of water and antifreeze coolant. This coolant helps regulate the temperature of the engine by absorbing heat and preventing freezing or boiling.
The heat is not working because you are very low on coolant, probably because of the leak. Seems to me that it should leak worse when it is running, so I am going to assume you are talking about the coolant overflowing the reservoir, in which case goes back to you being low on coolant and the engine boiling the coolant.
It is measured in Fahrenheit on US cars, and boiling temperature is 212°F. The scale indicates coolant temperature and over 200 would mean overheating, as steam could form in an unpressurized system.

Sometimes(depending on vehicle) it will even exit the reservoir tank through an overflow hose and appear to be a leak. Hope this helps! Chris not enough water or coolant in radiator.
Keep the cooling system at a predetermined rate of pressure. Raise the boiling point. Allow excess pressure to escape. Allow the cooling system to withdraw coolant from the reservoir.
