With a radiator cap pressure tester. The tool usually comes along with a cooling system pressure test kit.
When a radiator cap does not retain pressure, the coolant can boil at a lower temperature, leading to overheating of the engine. This can cause damage to engine components and potentially result in a breakdown. It is important to replace a faulty radiator cap to prevent these issues.
No, there should not be pressure in the radiator after cooling down. If there is still pressure, it could indicate a problem with the radiator cap or the cooling system, such as a leak or a failing pressure release valve.
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.
When the radiator cap is removed, the pressure inside the radiator is released suddenly, causing the water to boil explosively due to the rapid decrease in pressure. The water in the radiator is under pressure to raise its boiling point, and when that pressure is suddenly relieved, the water can boil and turn to steam very quickly, leading to an explosive release of steam and hot water.
The radiator cap may not be getting hot because it is located in a separate reservoir from the radiator itself. It is designed to maintain pressure within the cooling system and does not directly contact the hot engine coolant.
You attach a pressure test kit to where the radiator cap goes, and pressurize the system. If it holds pressure, it's good.
the radiator pressure cap was invented by Albert Einstein
