What happens when pressurizing coolant?
When pressurized to 15 PSI, the boiling point of coolant is about 45 degrees Fahrenheit higher than non-pressurized coolant. Otherwise, the coolant will steam and evoporate, which could lead to more serious automotive problems like overheating, a blown head gasket, a cracked engine or warped cylinder head.
Why do race cars use water instead of coolant?
Water alone boils at 100 degrees Celsius; much lower than the designed operating temperature of a combustion engine. The water will turn into steam and pressurize the cooling system beyond its designed capacity (around 14–20 psi) leading to boil over and overheating of the engine leading to catastrophic engine failure.
How does a liquid cooling system work on a radiator?
It includes; the radiator, which is mostly an aluminum radiator, the thermostat, hoses, water pump or coolant pump, a radiator cooling fan, heater core, bypass system, head gaskets, and few other components. The liquid cooling systems function by transporting the coolant through a passage in the engine blocks and heads.
What does it mean when your Radiator reservoir is full?
Suppose you notice that your radiator is empty, but your coolant reservoir tank is full. In that case, it might mean that there is or there are few damages in the components of the engine cooling system, which means that there is possibly a faulty radiator or radiator hose, a damaged gasket, or a radiator cap, or some other faulty components.
What does the pressure valve on a radiator do?
The radiator’s pressure valve offers a double-duty function. It allows refrigerant to flow into the expansion tank when pressure rises and then initiates reverse-flow when the pressure falls and the liquid is cold.
Why do I have hot water coming out of my radiator?
If you’re seeing gas bubbles or some boiling in the liquid when you remove the radiator cap, a cracked head or block may be to blame. Do not remove a radiator cap from a hot engine to check. You can experience a shot of boiling water exploding under pressure. Your local repair shop can perform test to identify cylinder head or engine block cracks.
Why is the water in a coolant system pressurized?
As the water heats up it expands. The caps come in different pressures that you can buy. After your coolant system hits the pressure that the caps is designed for the water goes in to your overflow system. The system is designed for pressure because it raises the boiling temperature.

What to do if radiator pushes coolant into resivior?
One for sure way is to take it to a shop, and have them test the the cooling system for HydroCarbons. Some might even do it for free since it takes only a second to do. Just warm it up, pull the radiator cap. Stick the exhaust gas analyzer just above the radiator opening, and if there is hc’s in it, you know you have a blown head gasket.
Why is water coming out of my radiator?
When I open the radiator cap you can hear air/pressure noise and the radiator takes about 3/4 to 1ltr water to top back up. Also when I run the car with cap off and rev it up it bubbles a bit and pushes some water out of radiator.
