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 editors from Shaoxing Automotive Network will introduce you to the “four-step method†for troubleshooting engine overheating.
one look
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 in the water tank, water pipes and joints. If no abnormality is found through the external inspection, the cooling water can be supplemented as required before continuing the driving. If the temperature is still too high after traveling a certain distance, 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.
Two touch
When the engine temperature is too high, you can use the hand to touch the temperature of the upper water pipe and the 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.
Three puts
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 high speed, and gently open the tank cover until gas is just released. At this time, part of the cooling water will flow out with the gas, so repeatedly, until you feel that the gas has been discharged. After troubleshooting, cooling water should be replenished promptly.
Four impulses
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.
