Why is there pressure in my radiator when the engine is cold?
Then, when Engine stops working, the temperature of coolant starting cool down then coolant wants to get all of its amount back (the vaporized water), but it can’t then it generates a sucking pressure inside the radiator. This is the pressure, you are talking about, in the coolant reservoir when engine got cold.
Why does a radiator still pressurized After cooling?
That raises the local temperature of the coolant increasing the pressure. It takes some time for that heat to dissipate and for the coolant to cool below the boiling point. Once that happens the pressure in the cooling system drops to slightly below atmospheric pressure as the steam condenses.
What is normal air pressure in a radiator?
At normal air pressure (1 atm*) water boils at 212 degrees Fahrenheit (100 degrees Celsius). So, if there was no cap on the radiator, the water would boil as soon as it reached 212. Modern engines are designed to operate in the 210 degree range for fuel efficiency and emission control.

Why does upper radiator hose keep building up pressure?
Q: Upper radiator hose keeps building up a lot of pressure and popping off. Car loses coolant and over heats. My upper radiator hose keeps building alit of pressure and popping off and car loses coolant and overheats. I changed radiator cap after reading that could be problem. My car has 191400 miles. Hello, thank you for writing in.
Why is coolant building up on my radiator?
Typically it is because the hose or the plastic neck that connects it to the radiator/component has failed. You will want to inspect both sides of the problem hose, and determine if the clamp is doing its job. Considering it is the top hose, the coolant is coming from the thermostat and flowing down through the radiator to be cooled.
What should I do if my radiator pressure is low?
Run the car till it warms up to operating temperature and the thermostat should be open. While it is warming up their should not be much pressure in the radiator hoses if their is it has a blown head. Shut the car off when it is warmed up and let it sit till it is completely cooled down and check for pressure in the hoses again.
