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.

How do you pressure test radiator cap?
To pressure test a radiator cap, you will need a radiator pressure tester kit. Remove the radiator cap, attach the pressure tester to the radiator neck, and pump it up to the specified pressure level. Observe for any leaks or pressure loss to determine if the radiator cap is functioning properly.
Should there be pressure in the radiator after cooling down?
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.
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 does the water in a car radiator sometimes boil explosevly when the radiator cap is removed?
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.
Why is the radiator cap not getting hot?
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.
Who invented the radiator pressure cap?
the radiator pressure cap was invented by Albert Einstein

Why does a brand new radiator cap not hold proper pressure?
It may not be the correct cap for the vehicle. It may be a weak cap, this can happen even with brand new caps.
