Engine temperature too high

Engine temperature too high

2022-05-05

Excessive engine water temperature usually causes the coolant in the radiator to boil, the power drops, the viscosity of the lubricating oil decreases, and the friction between engine parts increases, and it can even cause serious failures such as engine cylinder pull and cylinder head gasket burning. PLUS POWER GENERATOR summarized the main reasons for the high temperature of the engine and put forward some improvement measures at the same time.


1. Long-time overload operation

Long-term overload operation of the engine will increase its fuel consumption and heat load, resulting in excessive water temperature. For this reason, long-term overload operation of the engine should be avoided.


2. Insufficient coolant

The lack of coolant in the engine cooling system will affect the engine's heat dissipation effect and cause the engine to become hot. In this regard, the amount of coolant in the radiator and expansion tank should be checked frequently, and it should be replenished in time when the liquid level is low.


3. Fan belt overloose or fan deformed

If the fan belt is too loose, it is easy to cause the fan speed to decrease, causing the radiator to fail to perform its heat dissipation capacity, resulting in excessive engine temperature. In addition, the deformation of the fan will also cause the heat dissipation capacity of the radiator to not be fully utilized. In this regard, should regularly check whether the engine fan belt is loose and whether the fan shape is abnormal.


4.Debris attached to the surface of the radiator

The sundries attached to the surface of the radiator will not only reduce the heat dissipation area of the radiator, but also reduce the windward area of the radiator, resulting in a decrease in the heat dissipation capacity of the radiator and causing high engine temperature. The adhesion of debris on the surface of the radiator is the most common phenomenon.Here combines the structural characteristics of the radiator and introduces the precautions in the cleaning process.

Since the radiator is not easy to disassemble, only relevant parts can be disassembled. After disassembling the dust-proof net, use a brush or other tools to remove large debris, and then use high-pressure water or gas to flush the dust-proof net. The pressure of the water or airflow is recommended to be kept above 1MPa. In order to facilitate the cleaning of the core of the radiator, parts such as the air deflector and fan guard should be removed.


When flushing the radiator, the nozzle should be as vertical as possible to the radiator plane, the nozzle should be kept at a distance of 10-30mm from the radiator, and the nozzle pressure should be adjusted according to the thickness of the radiator core. If conditions permit, it can be cleaned with compressed air again after cleaning with high-pressure water flow, the method is the same as above. If the conditions are restricted, only compressed air can be used. The radiator should be moistened with water first, and then cleaned directly with compressed air. The gas pressure should be above 2.5MPa. After the cleaning is completed, the removed parts are assembled and re-assembled to complete the cleaning work.
