What if the car overheats? This is how the engine was "burned"!

Automobile radiator excavator tank oil radiator engineering machinery radiator causes overheating for many reasons, including the lack of coolant, cooling fan to cool the coolant shortcomings, thermostat shortcomings, coolant temperature sensor shortcomings. Assuming that the response is not correct, serious will lead to a costly engine to present shortcomings. Therefore, timely detection and correct disposal of overheating can effectively reduce the loss.


What effect does the engine overheat have on the engine?


1. Reduced inflation efficiency, resulting in power drop of the starter.


2. The tendency of early combustion and deflagration increases, which destroys the normal work of the initiator; At the same time, it is the additional impact load of the part to constitute early damage.


3, the normal clearance of the moving parts is destroyed, so that the parts can not move normally, so as to damage.


4. Mechanical properties of metal materials are reduced, resulting in deformation damage of parts.


5. The deterioration of lubrication aggravates the friction and wear of parts.


How does the engine overheat cause?


1. Poor heat dissipation of the initiator


Poor heat dissipation of the engine may lead to excessive water temperature in the water tank. And cistern USES time longer, the scale inside also can accumulate thicker and thicker, bring about radiator of cistern to dissipate bad, the water that temperature crosses tall cannot release heat, evolve thereby "pan". The vent hole of additional radiator is blocked also is a very common reason that forms heat dissipation bad. If the external plug is not ventilated, clean with a water gun, such as radiator internal plug, the application of detergent cleaning fluid cleaning.


Second, the cooling system is not working normally, resulting in poor ability to dissipate heat, at this time to check the tightness of the fan belt, fan blade can be deformed or broken.


Three, the thermostat according to the temperature of the cooling water automatically adjust the amount of water into the radiator, to ensure that the initiator in the appropriate temperature range, can play a role in saving energy. If the initiator is overheated, please check whether the thermostat works normally and when the thermostat works normally. Should be opened at 70℃, 83℃ when open. When the rising height of the valve is not less than 9MM, the thermostat can be put into water for heating inspection. If the thermostat cannot be turned over in regular humidity or the opening degree is not enough, the thermostat needs to be changed.


Finally, pay attention to the engine overheating do not turn off the engine, assuming that the fan belt and cooling fluid circulation are normal, then do not shut off, stop waiting for the engine cooling. In general, it is easy to think that the engine will cool down more easily after the engine is shut down. In fact, the cooling fan and coolant circulation will stop after the engine is shut down, which will make the engine even hotter. There are two spiral fans on the bumper side of the engine room, one is the cooling fan to cool the engine when the engine works, and the other is the air-conditioner fan to turn over the air conditioner. So when the car is overheating, assuming that the fan belt is not broken, it is best not to let the engine out, but also at the same time to turn over the air conditioning, so the engine cooling speed will be faster.
