Why is the upper radiator hose collapsed?

[DelAdalynn]

The upper radiator hose may collapse due to insufficient water in the radiator or a blockage in the radiator. Below are the specific reasons: Reasons for the collapse of car radiator hoses: The car radiator, also known as the heat exchanger, functions to dissipate heat by absorbing heat from the engine block and preventing the engine from overheating. Since water has a relatively high specific heat capacity, if the radiator malfunctions and heat cannot dissipate, the water temperature will rise rapidly, causing the upper radiator hose to collapse and leading to car issues. If this occurs, promptly visit a repair shop to inspect the cooling system, as the consequences can be severe. Temperature control in car engine blocks: During operation, the car engine generates heat, necessitating the use of water for cooling. There are numerous small passages in the cylinder block, and the radiator's role is to store backup water. When the water in the engine block reaches a certain temperature, the thermostat automatically activates the pump to circulate the backup water into the cylinder. At this point, the pipeline must deliver the backup water to the engine block, and the engine block's pipe then transfers it back to the radiator.
