What are the components and functions of the cooling system?

Components of the cooling system: thermostat, water pump, water pump belt, radiator, cooling fan, water temperature sensor, liquid storage tank, heating device, expansion tank, water jacket in the engine block and cylinder head, and other additional devices. Functions of the cooling system: 1. It can change the cooling intensity at any time according to the load, speed, and temperature changes of the engine to ensure rapid heating and maintenance of the engine at normal temperature; 2. It dissipates the heat generated during engine operation into the air. The cooling system must prevent both engine overheating and excessive cooling in winter. After a cold start, the cooling system also ensures that the engine heats up quickly to reach the normal operating temperature as soon as possible.
As someone who has driven for twenty years, the cooling system is like the bodyguard of the engine, consisting of several key components: the water pump, radiator, thermostat, fan, and coolant hoses. The water pump acts as the heart, continuously circulating the coolant; the radiator, with its honeycomb-like appearance, is responsible for dissipating heat; the thermostat functions like a smart switch, opening the valve to allow coolant flow to the radiator when the temperature rises; and the fan kicks in when the engine temperature spikes to assist. Its core function is to maintain the engine temperature around 90 degrees, preventing overheating or cold-related engine wear. Insufficient coolant or a clogged radiator can cause the temperature gauge to soar, leading to engine damage or even a breakdown on the highway. I recommend regularly checking the coolant level and replacing the coolant, paying extra attention to the fan operation in summer, which can extend the engine's lifespan and save a lot of money. With proper maintenance, the car runs smoother and consumes less fuel.
