How do you pressure test radiator cap?
With a radiator cap pressure tester. The tool usually comes along with a cooling system pressure test kit.
Why would steam be coming out from the radiator cap?
Radiator caps are pressure relief valves. They are rated at "pounds per square inch" and are designed to release some pressure from the radiator if it gets too high. If an engine overheats it can boil the coolant and this will cause the radiator cap to let out steam. Radiator caps DO lose their ability to regulate pressure and can release too soon. If the engine has not overheated, have the radiator cap tested and replaced as necessary.
Why is there pressure in your radiator if a thermostat is good?
You should have pressure in the cooling system. The radiator cap is marked as to how much pressure it is designed to hold, usually 15 to 17 lbs.
What is the PSI rating on the radiator cap?
The PSI (Pounds per Square Inch) rating is what pressure the radiator cap is designed to hold up to but not exceed in the cooling system.
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.
I have no pressure in my radiator after it has warmed up what could be causing this to happen?
Defective radiator cap? Leak in system (Pressure test)? Head gasket?
