FAQ

Frequently Asked Questions about Automotive Cooling Systems

Car cooling system works: through the water pump to the cold water in the tank to the cylinder, and then go through the cylinder head to take the cylinder and cylinder head work heat, into the water tank for cooling. The temperature of the cooling through the electronic fan. The thermostat performs the cooling system for large and small circulation. Take Santana 2000 as an example: to determine the bad way of the pump is: open the heater, if there is warm air, that hot water in the cycle, the pump is good. Judge the way the thermostat: touch the water tank on the water pipe and the next pipe, if the difference between the two tube temperature is very hot, the thermostat is good. Judge the fan method: first can open the cold air conditioning, look at the electronic fan does not turn, if the turn, the fan is good. Judge the temperature control switch method: the temperature of the tank on the temperature control switch unplugged, with a short wire connector on both sides of the connector (the plug has three holes), the fan should turn.

Classification of cooling systems

Cooling system in accordance with the different cooling medium can be divided into air-cooled and water-cooled. If the high-temperature parts of the engine heat directly into the atmosphere and the cooling device called air-cooled system. And the heat first passed to the cooling water, and then into the atmosphere and the cooling device called water cooling system. As the water cooling system cooling evenly, the effect is good, and the engine running noise is small, the current widely used motor vehicle water cooling system.

How long will the cooling system in the car care be maintained?

In areas where the climate is relatively mild, the coolant should be replaced every year and the car cooling system should be flushed once.

The size of the engine cooling system is the state of each cycle

Small cycle refers to the water from the pump to the engine inside the cycle, the big cycle is through the tank engine cycle

Why is the engine cooling system?

Four, cold start dry friction. US General Motors' research shows that when the car engine stops for 4 hours, all the lubricating oil on the friction interface will flow back into the lubricating tank. At this time to start the engine, because the pump was too late to hit the lubricating oil parts, a short period of time will produce cyclical lubrication loss of dry friction, resulting in severe abnormal wear and tear of the engine. This kind of strong wear is simply unable to solve the lubricating oil. (Another relevant research that this strong wear and tear accounted for more than 70% of the total wear of the engine)

Engine cooling system composition and working principle?

An engine is a machine capable of converting other forms into mechanical energy, including engines such as internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), motors, and the like. Such as internal combustion engine is usually the chemical energy into mechanical energy. The engine is suitable for both the power generating device and the entire machine including the power unit (eg gasoline engine, aero engine). The engine was first born in the UK, so the concept of the engine is also derived from English, its original meaning refers to the kind of "power of the mechanical device."

How should the car cooling system be maintained?

Pay attention to the technical state of the ministry: If the radiator leaks, should be repaired, if found the pump, the fan rotation or swing or abnormal sound, it should be promptly repaired. If you find the engine overheating, should promptly check whether the lack of water, if the water should be shut down. To be cool after the addition of cooling water. If the thermostat is not working properly caused by the engine operating temperature is too high too low, it should be promptly repaired or replaced.

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?

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
