What Causes the Coolant to Stop Circulating?

[BraxtonMarie]

Coolant circulation failure may be caused by malfunctioning water pump or thermostat. Relevant information is as follows: Causes: Coolant circulation failure may result from faulty water pump, thermostat, or clogged coolant passages. Non-circulating coolant significantly impacts the engine and may cause engine damage. Concept: The radiator, also known as the heat exchanger, is the core component of a vehicle's cooling system. Its function is to dissipate heat - the coolant absorbs heat in the water jacket, releases it when flowing through the radiator, then returns to the water jacket to complete the continuous cooling cycle. This process regulates engine temperature by absorbing cylinder block heat and preventing engine overheating. Due to water's high specific heat capacity, its temperature doesn't rise dramatically after absorbing engine heat. The engine's thermal energy is transferred via the liquid coolant circuit, using water as heat carrier, then dissipated through large-area cooling fins via convection to maintain optimal operating temperature.
