What else can I help you with?
Why is your car coolant bubbling?
1) Your engine is overheating and the coolant is boiling. Or 2) Exhaust is leaking into the coolant, probably through a bad head gasket or cracked head.
What can antifreeze do to the boiling point of the water in a car's radiator?
Antifreeze raises the boiling point of water in a car's radiator by reducing the vapor pressure of the coolant mixture. This helps prevent the engine from overheating by allowing the coolant to operate at higher temperatures before boiling.
Why cold boiling happens in engine?
Cold boiling in an engine occurs when the temperature of the coolant drops below the boiling point due to low pressure, causing the coolant to vaporize despite being at a lower temperature. This phenomenon can result from inadequate coolant circulation, a malfunctioning thermostat, or air pockets in the cooling system. As vapor bubbles form, they can disrupt coolant flow, leading to overheating and potential engine damage. Proper system maintenance and pressure regulation are crucial to prevent cold boiling.
What is the hissing from overheating car?
It's steam from boiling coolant (or water) coming out of the overflow hose connected to the top of the radiator just below the level of the cap.
What does it mean when your surge tank boiling?
If your surge tank is boiling, it means that the coolant is reaching a temperature where it is beginning to vaporize and bubble. This can be due to issues such as overheating, low coolant levels, a faulty radiator cap, or a malfunctioning thermostat. It is important to address this promptly to prevent damage to the cooling system.
Why is it not safe to open the radiator cap when engine is overheating?
When the cooling system is overheated, the coolant is at pressure. Removing the radiator cap will release the pressure, and allow the coolant to boil, probably splashing you with boiling-hot radiator fluid. Your arms and hands will certainly be burned, and there's a good chance that the boiling coolant will splash your face. You wouldn't like it if that happens.

Why is ethylene glycol added to water in radiator during summer?
Ethylene glycol is added to water in the radiator during summer to act as an antifreeze and coolant. It helps prevent the water in the radiator from freezing in cold temperatures, while also raising the boiling point of the coolant to prevent overheating in hot weather.
Is 'water only' used as a coolant in cars?
The use in modern engines is not recommended because of the high temperatures encountered by the coolant. Etylene glycol or other antifreeze products also raise the boiling point of the water, to better avoid overheating.
Why does the coolant gauge go to 200 degrees?
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.
Why is your 1992 concours boiling?
The term "boiling", I am assuming, is referring to the coolant bubbling out of the radiator or overflow. This indicates that your engine is overheating, and should be shut off IMMEDIATELY. It is possible that er-repairable damage has already been done to an engine that has boiled over.
Does a mix of coolant and water have a higher boiling point than water alone?
Yes. Water boils at 212 degrees. A 50/50 mix of water and antifreeze boils at 223 degrees. The temperature of the coolant can sometimes reach 250 to 275 F (121 to 135 C). Even with ethylene glycol added, these temperatures would boil the coolant, so something additional must be done to raise its boiling point. The cooling system uses pressure to further raise the boiling point of the coolant. Just as the boiling temperature of water is higher in a pressure cooker, the boiling temperature of coolant is higher if you pressurize the system. Most cars have a pressure limit of 14 to 15 pounds per square inch (psi), which raises the boiling point another 45 F (25 C) so the coolant can withstand the high temperatures. Antifreeze also contains additives to resist corrosion.
