Why Did My Coolant Hose Burst? The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. Another common problem is clogging of the smaller radiator runoff hose, which leads to the coolant tank. As the engine cools, if fluid cannot return to the tank, this will also cause a vacuum.
What is the primary cause of coolant hose failure? Electrochemical degradation (ECD) is the number one cause of failure on the rubber portion of coolant hoses. ECD weakens the hose from the inside and is therefore not obvious by visual inspection.
What causes a radiator hose to explode? When coolant near boiling passes through worn old radiator hoses, it increases the pressure in the radiator and in the hoses that connect it to the engine. Radiator hoses are designed to handle a specific amount of pressure; if that pressure increases to an excessive level, the hose will begin to swell and could burst.
How do I know if my coolant hose is bad? If you suspect either radiator hose is failing, watch for the following symptoms:
Leaking coolant. If you notice green fluid beneath your vehicle, chances are your vehicle is leaking coolant.
Engine overheating.
Low coolant.
Collapsed radiator hose.
Radiator hose is broken.

Are silicone radiator hoses worth it?
Silicone hoses benefit from superior flexibility compared to rubber. They maintain this flexibility over their lifespan unlike rubber hoses. This reduces the risk that your hoses will split, harden, or become dry rotted. Silicone hoses last practically forever and might possibly outlast your car.
How can you tell if your thermostat is open?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
Is it OK to run an engine without a thermostat?
You may think your engine would overheat without a thermostat in place, but actually, the opposite is true.
