As the pressure in the system drops — when the engine is off and cooling down — the pressure cap allows the excess coolant in the overflow tank to return to the radiator. If the radiator cap is malfunctioning, the vacuum created in the system will collapse the hose.

Can a bad thermostat cause radiator hose to collapse?
Stuck Thermostat: If the thermostat is stuck open, it can cause the radiator hose to collapse. When the thermostat is stuck closed, it can prevent the engine from reaching its normal operating temperature and can cause the engine to overheat.

Can you drive with a collapsed radiator hose?
You must pull to the side of the road and shut off the engine as quickly as possible. Continuing to drive with an overheated condition can cause severe engine damage. It's worth noting that engine overheating problems may derive from several other causes besides a collapsed hose.
Why Car Radiator Hose Collapse When Cold.
What causes lower radiator hose to collapse?
Molded lower radiator hoses tend to collapse with an increase in engine rpm because the water pump draws more coolant out of the radiator than the hose can handle — negative pressure at the radiator and lower hose causing collapse.
What happens when radiator hose collapses?
Both Dex-Cool and Stop Leak deposits have a tendency to build up in the radiator cap mechanism. If with a collapsed hose you remove the radiator cap (when the engine is cool), and it is gummed up, one or both of these products may be the cause. Either follow the cleaning steps above or replace the cap.
What would cause radiator hose to collapse?
The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. Caps are rated around 14–16 psi. Under normal circumstances, caps should release the negative pressure caused when an engine cools down and the liquid coolant contracts.

How To Fix Collapsed Radiator Hose Lancer
What happens when your radiator hose explodes?
If your coolant hose has a leak, it will fail to transfer coolant from the radiator or engine towards the water pump. This creates damage for the rest of your vehicle. Your coolant hose is not attached properly.
How do I know if my radiator hose is collapsed?
A collapsed radiator hose looks like a long skinny flat tire. Very noticeable. One or both hoses may go flat if the cooling system experiences a localized or complete vacuum (negative pressure) condition.
