Causes and Solutions for Overheating of Automotive Engines


  Overheating of the engine is a common failure, which can lead to engine power generation and economic decline. In severe cases, the engine will be damaged. Therefore, such failures should be promptly eliminated. The following describes the solution for troubleshooting engine overheating.

Found that the temperature is too high or the temperature indicator kept shining, to stop and check to see if the tank cooling water is normal, there is no leakage at the water tank, water pipes and joints. If no abnormality is found through the surface inspection, the cooling water can be supplemented as required before continuing the driving. If after traveling a certain distance, the temperature is still too high, the cooling water is reduced by a large number of parking inspections. This is due to the fact that the water jacket of the cylinder block is lost due to blisters or perforations. After finding this fault, repairs should be carried out and should not be taken lightly.


When the engine temperature is too high, you can use the hand to touch the temperature of the upper water pipe and underwater pipe to determine the fault. If the temperature difference between the two pipes is very large, it can be judged that the thermostat does not work. If the accessories are not available on the way, the thermostat can be removed and replaced immediately after the unit is returned.

If there is air in the cooling system, air resistance will be formed, causing poor circulation of the cooling water, causing the engine temperature to be too high. The following methods can be used to deflate : Let the engine run at a high speed, and gently open the tank cover until gas is just released. At this time, some cooling water will flow out with the gas, so repeatedly, until you feel that the gas has been discharged ( At this point, the temperature of the water pipe will be significantly different . ) After troubleshooting, cooling water should be replenished promptly.

    If the vehicle is driving on dirt roads or muddy roads for a long time, some dirt will adhere to the radiator. Over time, it will affect the heat dissipation effect and cause the water temperature to be too high. The radiator grille can be blown with compressed air and then flushed with a hose.
