Diagnosis and Treatment of High Temperature of Engine
Engine high temperature refers to the sudden increase of engine operating temperature due to some reasons, which affects the normal operation of the engine. The emergence of high temperature seriously restricts the normal operation of the mechanical engine and accelerates the wear of fuel, parts and other components, so it should be treated as soon as possible according to the actual situation.
The general reasons for high temperature of engine can be divided into two categories: one is the engine itself, such as insufficient coolant flow rate and too little antifreeze, poor cooling system performance and so on; the other is environmental temperature, such as driving in high temperature environment or in the process of parking, the sun is directly exposed to the car body surface, etc.
The professional treatment for high temperature of engine is to first check the coolant and its quality, and see if the water pump, radiator and cooling fan are normal. It is necessary to pay attention to the following several aspects when checking in detail:
1. Check whether the coolant is sufficient. Before checking, the extinguishing water in the water tank should be closed first, then the upper and lower pipes of the radiator should be bunched out and check whether the water level is higher than the lower pipe. If the coolant is not enough, you should add it timely.
2. Check the concentration of coolant. If there is a change in the concentration of coolant, it should be replaced in time.
3. Check the coolant strength. If the coolant strength is lower than 50%, it can not effectively cool the engine, so it needs to be replaced in time.
4. Check the thermostat. If it is determined that the thermostat can not accurately control the temperature, the corresponding repair should be carried out.
5. Check the cooling system. Good sealing performance and reasonable cooling parameters can give full play to the cooling effect of the system.
6. Check the belt tightness. If the belt is too loose, the fan can not operate normally, so the belt should be adjusted to the correct position.
7. Check the tension of the fan belt and the water pump. If the tension is too small, the fan or water pump will not rotate properly, causing high temperature.
8. Check the performance of the radiator. If the angle of the radiator or the fan speed is too low, or the tank is blocked, the cooling capacity of the radiator will drop, resulting in engine high temperature.
9. Check the water pump. If the water pump is damaged, the coolant can not be circulated normally, resulting in engine high temperature.
The above are the nine detailed methods which can be used to diagnose and treat high temperature of engine. In addition, it is also important to adjust the engine oil, replace the oil filter and pay attention to engine running-in process. In short, when the engine temperature is higher than normal, you should stop the machine in time and carry out checks and repairs. Once the fault is found, it should be solved as soon as possible so that the engine can continue to operate stably and efficiently.
