Question:

What is the role of the engine cooling system?

What is the composition of the water-cooled water cycle? What is the composition of the water pump? Water pump structure has several parts of the composition? How to replace the pump and preload the pump belt? How to detect the good performance of the thermostat ? How to correctly replace the coolant? Radiator excessive scale of the treatment methods which lead to the engine water cooling system is the main reason for the high temperature?

Answer:

1 water cooling composition shutters radiator radiator water tank cover fan water pump thermostat water temperature table water jacket water pipe discharge switch compensation bucket rubber hose and other 2-way belt drive pump and then pressurized by the water pipe into the cylinder block into the water tank Cylinder head water jacket and then along the cylinder head outlet through the thermostat and outlet pipe into the radiator, of course, the fan also has a cooling effect of cooling water into the bottom of the radiator and then sucked from the pump so the cycle is now generally forced 3 centrifugal Pump impeller pump shell inlet pipe outlet pipe straight blade bending blade there are other here do not say friends 4 to replace the pump to be carried out at normal temperature is to open the car shell is not realistic to say how to change 5 now a lot With a thermostat to put the thermostat into the hot water container to gradually increase the temperature measured with a thermometer thermostat valve open and fully open when the temperature and full of the valve lift does not meet the requirements should be replaced 6 generally can be used Cooling water, but the general car are not used well water or water rivers have 7 radiators removed to put away the water after the rinse if the kind of internal scar of the kind of solid to add what can be sold to sell the mechanical parts of the 8 The reason for a lot of fans such as a bad part of the radiator blocked and cooling water for a long time did not change and so on
To personally experience and repair these things you can understand the role they play by answering these questions and can not let you really understand
Under the action of the pump to cool the water in the cooling mechanism, the high-temperature parts of the heat away and cooling, through the radiator will cool the heat dissipation in the atmosphere, so that the engine temperature to maintain the normal working range.
The problem is very complicated, but the answer is very simple. The engine is divided into oil, circuit, cooling system. The main function of the cooling system is to heat the engine. But the oil also has the role of heat. The engine has a sink, circulation, water tank, cooling fan. And a spare kettle. Loop is the tank to the engine ah, and then come back. The pump is an individual and has a fan. If the pump is broken need to be replaced, put the bad removed to replace the new on the line, but to adjust the size of the generator to Panasonic belt, and tighten the belt. The performance of the thermostat can be removed when the hot water with hot water, if you can bounce is normal, and vice versa is bad. When the replacement of water or coolant when the water tank under the drain valve to open, run the coolant after the discharge valve installed, the introduction of new coolant. After filling the car to cool the liquid circulation, Tim enough coolant, cover the water tank cover, fill the spare kettle can be. The reason for the high temperature of the engine is 1, lack of coolant. 2, the cycle is not good. 3, the cooling fan does not work. 4, too much scale in the tank. 5, the speed is too slow.
