8 Reasons Why The Engine Temperature Of The Factory Crane Is Too High:

8 Reasons Why the Engine Temperature of The Factory Crane is Too High:

 

1. Leakage of cooling system or lack of cooling water;

 

2. The indication of the water temperature gauge is forbidden or out of order;

 

3. The water pump is damaged, the fan blades are reversed or deformed, and the wind ring is damaged;

 

4. The water pump and fan belt are too loose or broken;

 

5. The thermostat is damaged in the closed position of the main valve;

 

6. The cooling system has too much scale and the heat dissipation effect is poor;

 

7. Radiator guard net or radiator core ventilation channel is blocked by sundries, resulting in poor heat dissipation;

 

8. The engine is overloaded for a long time and the oil supply time is too late.

 

 

Solution for Overheating of Engine

 

When the engine has a fault of high water temperature during operation, it should pay attention to observe the fault phenomenon, find out the cause and eliminate it.
 

First of all, check whether the water temperature gauge is out of order. If it is forbidden or out of order, it should be replaced;
 

Then check whether the water tank is short of water, whether the water inlet pipe and the radiator are broken and leaking. In addition to direct inspection from the outside, you can also check the leaking parts by pumping air.
 

The leaking part of the radiator can be repaired by soldering. If a certain heat pipe is heavy, both ends can be clamped and blocked.
 

Minor water leakage was found during the operation of the crane in the factory building, which can be blocked with a building block and repaired after parking.
 

If it is not the above factors, you should further check whether there are cracks in the engine casing, whether the water circle is damaged, and whether the water pump drain hole is leaking. Finally, check whether the exhaust valve of the radiator cover is invalid, and replace it if it is invalid.

 

If it is not the leakage of cooling water, the fault should be analyzed and eliminated in two situations.

 

 

1. Suddenly the water temperature is too high.

 

First check whether the radiator is overheated. If the temperature of the radiator is too high, it means that the cylinder gasket is damaged. At this time, pay attention to check whether the joint surface between the upper plane of the body and the cylinder head is seriously warped and deformed. If it is deformed, it should be repaired in time.
 

If the temperature of the radiator is not high, it means that the cooling water circulation is poor, and you should check whether the fan belt is broken or severely slipped.
 

If it is normal, then check whether the radiator outlet pipe is deflated, whether the inner hole is delaminated and blocked, and find out the cause and eliminate it. The emergency method is to put a large spring support in the deflated pipe.
 

Then check if the expansion tube of the thermostat is broken, and the crack should be replaced.
 

If the thermostat is normal, it means that the water pump is damaged, and the water pump should be carefully checked and repaired.

 

 

2. Non-sudden water temperature is too high.
 

For the phenomenon of excessive temperature that does not appear suddenly, the engine speed should be increased to observe whether the water inlet is turned over, and at the same time, pay attention to whether there is a lot or a small amount of water turned over.
 

If a lot of water is turned over and the temperature of the radiator is uneven, it means that some cooling pipes are blocked, and more attention should be paid to it in the cold winter.
 

When the water inlet is slightly turned over and the engine temperature is low at first and then high, it indicates that the water distribution pipe is damaged or blocked and should be replaced in time.
 

If it is not for the above factors, it may be that there is too much scale in the cooling system and the water channel is not smooth.
 

If the water is not turned over at the water inlet, the surface of the cooling system and the mechanical parts of the engine should be carefully inspected and analyzed.
 

First of all, check whether the blinds are closed or the opening is insufficient, and whether the fan rotation is normal. If everything is normal and the engine is still overheated, you should check the air volume of the fan.
 

If the air volume is insufficient, the angle of the fan blade should be adjusted, and the blade head should be bent properly or the fan blade should be replaced.
 

Under the normal condition of the cooling system, if the engine is still overheated, the factors of use should be considered.

 

In a word, there are many reasons for the overheating of the engine of the factory crane, and the above methods can be flexibly used according to the specific situation to check and scan.
