What happens if there is no pressure in the radiator?
If there is no pressure in the cooling system, the coolant will boil off. On the other hand, if the pressure was allowed to increase above 16 PSI the cooling system, including the hoses and even the radiator, could simply burst or even explode if the conditions were right. Never lose sight of the fact that a liquid expands as it gets hotter.
How does a radiator or cooling system pressure test work?
A radiator or cooling system pressure test is useful when finding a radiator leak or a blown head gasket. This tool attaches to the top or the radiator or coolant reservoir and enables air pressure to be pumped into the system including the engine block, cylinder heads, coolant hoses, heater core and radiator.
What are the benefits of increasing radiator pressure?
The increase in pressure in the cooling system is where the cooling benefits emerge. In the heads principally, the pressure reduces small air pockets and it reduces the onset of nucleate boiling and preignition.

What happens if there is too much pressure on the radiator?
Because cooling systems are designed for specific pressure. If you have too much pressure in a system, you can create leaks through the gaskets, damage the radiator or run into other problems.
How does the radiator cap affect the cooling system?
First, the radiator cap is an important part of the cooling system. It is designed to hold a certain amount of pressure inside the system, and to release the pressure when it exceeds a pre-determined level. Why do you want pressure in the cooling system? Actually, you don’t get a choice.

What happens if you remove the seal from a radiator?
If you remove that seal from an old radiator cap, you have a cap that will keep the coolant in, but will not retain any pressure. A small leak leaks much more slowly when there is no pressure in the cooling system. The seal is not meant to be removable.
