Can a bad radiator cap cause the hose to collapse?
You may have a bad radiator cap if the radiator hose collapses. The vacuum won’t be released by the radiator cap properly and it will cause the radiator hose to collapse during the cooling down period. If this happens, inspect the cap to see if there is any damage.
What does a spring loaded radiator cap do?
To avoid overpressurizing, which can damage components of the system, a spring-loaded valve on the radiator cap vents excess coolant into the expansion tank (also known as reservoir). Under lower pressure, the cap draws the coolant back into the cooling system.
Where does the coolant go in a radiator?
This is where the second bit of coolant system magic occurs. The radiator has a cap or pressure valve which, when the pressure reaches around 15psi, opens, allowing the coolant to flow into the expansion tank mentioned earlier, so relieving the pressure.
How can you tell if your Radiator Cap is stuck?
Below are the top 5 signs. If the radiator cap is stuck, fluid cannot get released. This will cause pressure to build inside of the radiator, causing the hose to leak or break open. If you notice coolant fluid near the radiator or the radiator cap, then you clearly have leaky coolant.

What does the pressure cap on a radiator do?
The part of a vehicle known as the “radiator pressure cap” contains 2 valves. Its purpose is to contain coolant in the radiator and ensure that the cooling system remains pressurized.
Can a leak in the coolant cap cause an overheated engine?
Leaky coolant or air in the cooling system can lead to an overheated engine. If you notice your engine getting too hot, don’t look under the hood unless you’ve turned the engine off. That way, the engine can remain cool as you check it out. If there is coolant fluid near the radiator cap, there could be damage to the pressure cap.
