Radiator has air pressure indicating that there is no pressure relief in the pipelines, which is a normal phenomenon. Introduction to the radiator: The car radiator, also known as the heat exchanger, is a key component of the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, achieving temperature regulation. It is an integral part of the car engine. Main purposes of the radiator: The function of the cooling system is to dissipate excess and useless heat from the engine, ensuring that the engine operates at normal temperatures under various speeds or driving conditions. The radiator is the heat exchanger for water-cooled engines, maintaining the engine's normal working temperature through air convection cooling. Once the engine coolant in the radiator boils and vaporizes due to high temperature, causing the pressure to exceed the set value, the radiator cap releases the pressure, reducing the coolant and preventing the cooling system pipelines from bursting. During normal driving, pay attention to whether the engine coolant temperature gauge on the dashboard is normal. Other factors, such as engine cooling fan failure leading to increased engine coolant temperature or cooling system pipeline leakage, may also cause a reduction in coolant. Before adding distilled water, check whether the amount and frequency of coolant reduction are normal.
