The automotive water cooling system consists of a water pump, radiator, cooling fan, thermostat, compensation bucket, water jacket in the body and cylinder head and other auxiliary devices. Among them, the water pump is a centrifugal water pump, whose function is to pressurize the coolant and ensure the circulation of coolant in the cooling system, which is an important part of the cooling system.

Automotive water cooling system components:

1. Water pump: the water pump is the core component of the cooling system. The water pump makes the coolant flow and cools the engine. If the water pump is damaged, the engine water temperature will rise.

2. Thermostat:The role of the thermostat is to distinguish between the large and small circulation, so that the engine temperature quickly reach the ideal state. It also saves fuel when the water temperature comes up.

3. Water temperature sensor: the water temperature sensor is mostly installed in the engine outlet, the main measurement of the engine water temperature, as the basis for fuel injection control.

4. Water tank: the water tank stores a large amount of coolant, is the engine and the outside world for heat exchange medium, can be discharged through the water tank engine heat.

5. Tank Fan:When the water temperature reaches a certain temperature, the module will control the work of the electronic fan to discharge the heat in the tank.

6. Water hose: there is no cooling system without water hose connection, there are many water hoses in the car, most of them are rubber hoses. If the water pipe leaks, it should be repaired in time.

How to maintain the cooling system

First look at the water tank. Normal water tank should be at the same temperature when traveling. If it is cold and half hot, you can judge the water tank blockage. The water tank can be connected to a water pipe with a pressure of 2 kilograms. If the blockage is severe, it can be backwashed with a small amount of detergent. Dirt in the water tank should be cleaned and observed for leaks.

Second, look at the thermostat. Some people think that removing the thermostat will prevent high-end water temperatures. If the thermostat function does not result in high water temperatures, the test time of running at low temperatures can be very harmful. Also, many engines have thermostats that work both ways. When the thermostat is closed, the cooling water is forced into a small loop. When the thermostat is open, the minor circulation is closed and the cooling water is fully circulated. If the thermostat is not installed, less water will actually flow to the larger circulation and the water temperature will rise due to the throttling effect of localized resistance in the pipes.

Finally, check the pump. There are three ways to damage the pump:leaks, losses and impeller corrosion. When the engine speed reaches a certain point, the pump impeller can not reach the corresponding speed, resulting in poor water circulation. The fan is a major component of the cooling system. Some cars have eliminated fixed fans and replaced them with electromagnetic and silicone clutch fans. It is characterized by a fan that does not work when the car is cold and dissipates heat to the maximum on a hot car. The main failure of fan clutches is oil leaks, while the main failures of electromagnetic fan clutches are water temperature switches, circuit damage and damaged electromagnetic coils.
