4) Collapsed radiator hose Hoses collapse when they become soft or weak or, occasionally, due to a cooling system fault. No matter the cause, an inspection must be performed– a collapsed hose cannot flow coolant properly which can result in the vehicle overheating and, eventually, engine damage.

What does it mean if the radiator hose is soft?
A radiator hose in poor condition feels very hard, spongy, or soft. You may find a single soft spot as opposed to the entire hose being soft. A soft hose or a hose with a soft spot should be replaced.
Can radiator hose cause overheating?
Engine overheating
The vehicle's engine should not overheat, so as soon as you notice this symptom, it means something is wrong with the cooling system. ... The radiator hose is the most common cause for overheating.
Is the top radiator hose supposed to be hot?
The main thing to worry about is after the engine reaches normal operating temperature that both the upper and lower radiator hoses are of the same or nearly the same temperature. If not either you have a bad thermostat, restricted radiator or an air bubble in the cooling system.
Should radiator hose be hard when hot?
Yes, a radiator hose should be hard when your car engine is getting hot, because a high hot water pressure is building up inside the engine block and the radiator, the radiator cap is spring loaded, it will release the pressure to let the boiling coolant return to the overflow reservoir.
What happens when radiator hose collapses?
Yes, a collapsed hose can cause overheating. If you are driving when a hose goes flat, coolant flow will be restricted. Your instrument panel will give you an elevated temperature indication and/or an overheating warning light. You must pull to the side of the road and shut off the engine as quickly as possible.
Can a collapsed radiator hose cause overheating?
A collapsed radiator hose doesn't always make itself known, so it's best to be vigilant and look under the hood every now and then. Engine overheating is not necessarily a cause or effect of a collapsed hose.
Can I drive with a broken radiator hose?
You can drive with a broken rad hose only until all the coolant has leaked out. At that point the engine will overheat and seize up. When this happens, you will need to buy a new engine.
How do I know if my coolant is circulating?
After your engine is warm, feel the radiator near the bottom. If it's still cool but the top part of it is hot, you're not circulating coolant. That could also mean a stuck thermostat though. Watch out for the fan though, it will severely damage your fingers if you get them stuck in it.
Why is my top radiator hose hot and bottom cold?
What happens when a radiator is not circulating, the top hose is hot, and the bottom hose is cold? - Quora. That's the way it should be when the coolant is circulating. The hot coolant enters by the top hose, is cooled by the radiator and then cooled coolant re-enters the cooling system from the bottom hose.
Why is upper radiator hose swollen?
If your engine has overheated (due to a stuck thermostat, low coolant or for some other reason), it's possible for superheated coolant to swell the hose. Swollen hoses should be replaced as soon as possible. This applies to radiator hoses, as well as other hoses under the hood.
What causes pressure in radiator hose?
As water heats up it expands increasing pressure in the system. Being that water flows through the radiator hose it is also under pressure. The systems are sealed to hold this pressure for one main reason. Water under pressure has a higher boiling point.
What does a hard radiator hose mean?
hard hoses can be a sign of the cylinder pressure entering the cooling system because of head gasket or cracks. The hoses are suppose to get hard as the engine reaches operating temp but you should be able to squeeze them especially after a short drive where the car reached operating temp.
What causes radiator hoses to flatten?
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.
