Why is my radiator pushing coolant out?
Why is my radiator pushing coolant out?
Another thing that can cause coolant to be pushed out is boiling of coolant. Remember that a major point of having a radiator cap is to keep the system under pressure in order to raise the boiling point of the coolant. If there is no radiator cap, coolant can start to boil within the engine after it has warmed up some.
When does a radiator become a pressurized system?
A radiator is a non-pressurized system when cool, but when it gets hot it becomes a pressurized system. You can easily check the radiator fluid level when it is cold, but if you check it when hot, you will most likely be burned by the hot water and antifreeze mixture.
What causes a radiator to have too much pressure?
Too much pressure can be cause by a clogged radiator (lime build up), a restriction in the system or a bad radiator cap. The radiator cap is designed to release pressure. Some radiator tanks are made from plastic. Because of the amount of heat the radiator is subjected to on a daily basis, these tanks eventually wear out and may crack.
What causes a radiator head gasket to blow?
If a radiator hose suddenly blows off its water outlet, or the dipstick won’t stay put, this could be the reason. If a head gasket has failed between the water or oil passage and the outside of the engine, the result can be a simple coolant or oil leak.
Why is the water in a coolant system pressurized?
As the water heats up it expands. The caps come in different pressures that you can buy. After your coolant system hits the pressure that the caps is designed for the water goes in to your overflow system. The system is designed for pressure because it raises the boiling temperature.

What causes coolant to overflow from the radiator?
Your problem may simply be a loose or damaged cap not keeping coolant where it needs to be. The radiator cap is designed to allow access to fluids in a ‘closed’ system. The coolant used to cool the engine does so at maximum efficiency when kept at specific pressure. Check your owner’s manual for proper cap replacement.
What does the pressure valve on a radiator do?
The radiator’s pressure valve offers a double-duty function. It allows refrigerant to flow into the expansion tank when pressure rises and then initiates reverse-flow when the pressure falls and the liquid is cold.
