A 50/50 mixture of water and ethylene glycol antifreeze in the cooling system will boil at 225 degrees if the cap is open. But as long as the system is sealed and holds pressure, a radiator cap rated at 15 psi will increase the boiling temperature of a 50/50 coolant blend up to 265 degrees. If the concentration of antifreeze to water is upped to 70/30 (the maximum recommended), the boiling temperature under 15 psi of pressure goes up to 276 degrees.

Why does the water in a car radiator sometimes boil explosevly when the radiator cap is removed?
Water under pressure has a higher boiling point, if the water is already hot enough to boil it will suddenly erupt when the cap is removed and pressure relieved.
What can happen if you use straight antifreeze in your radiator?
If your use anything more concentrated than about half anitfreeze and half water, the radiator water will freeze at a considerably warmer temperature. There will be less protection. Also, antifreeze actually helps keep your car running cooler in summer. If you use straight antifreeze, the car will "boil over" at a much lower temperature. There will be less protection.
Does the water in the radiator reach a boil?
Water in a car radiator does not normally boil. In some old cars, the cooling systems would run at about 220 degrees Fahrenheit. The pressure would be high enough so that the water would boil at 250 degrees. Today, you do not put water in radiators but coolant. It is much more efficient than water for cooling engines.
Why does your car loose a lot of water?
It can mean that the temperature is too hot or you have a bad radiator cap.
Why does the water in a car radiator sometimes boil explosively when the radiator cap is removed?
Because when the cap is removed the liquid inside wants to start cooling itself. The heat energy is released by boiling.
How do you add water to a jetta radiator?
When a car is hot, keep the car running and add water to the radiator. When a car is cold, you can simply put the water into the radiator.
Your car is not registering hot but your overflow tank will boil?
Try a new radiator cap.
Does the heater in a car use the gas or the electricity of the car?
Most cars that is powered by a gasoline engine uses the heat from the radiator to heat the interior of the car. A gas engine uses a water pump that circulates water through the engine and out to the radiator to transfer the heat generated by the ignition. The radiator cools the water and returns it to the engine to keep it cool. Some of this heated water is sent to the small radiator used to heat the air that is blown into the car's interior. The fan that blows the air is powered by Electricity. This can be tested when you have a engine that is trying to overheat during the Summer. If the gage shows the temperature going high, then turn on the heater and it will cool the temperature just slightly. The reason is that the heater's radiator acts as an extra radiator that will help cool the water's temperature. Of course, you will sweat a lot with the heater running full blast during the summer.
How can you tell if your water pump go bad?
I presume you mean car water pump? If the water pump is faulty the car will over heat and the temperature gauge will go up. Make sure that there is enough coolant in the radiator, the radiator or the hose pipe is not leaking and the radiator cap is not faulty, as all of these faults can cause overheating. Once you have excluded these then you can blame the water pump.
What do you put in a car's radiator?
Water
What does a radiator do in a car?
A radiator cools the water that flows around the engine.
Do you use coolant or distilled water in a car radiator?
You can use almost any liquid in a radiator, but water is not the best choice. Water boils at 100 degrees (and your engine gets way hotter than that), also it freezes at zero degrees and in many places it gets colder than that.Engine Coolent is an additive that you add to water or replace the water in a radiator. Coolant raises the boiling temperature and lowers the freezing temperature so that your radiator will work in the widest possible circumstances.
