What if the excavator engine boils

The engine boiling phenomenon can no longer be called a simple fault problem, and may even rise to a safety accident. At the same time, it is also called one of the most expensive faults by old drivers in the industry. Because the boiling of the engine may cause more serious steel sticking, cracking, and even scalding of the surrounding machine hands!
In addition, many friends may think that as long as the engine survives the hot weather in summer, it can escape. In fact, the boiling problem has a chance to happen in cool autumn and even cold winter! Today, let's have a comprehensive understanding of the engine.

Causes of excavator engine boiling

Although the engine boiling seems very dangerous, the reason is not very complex. In the final analysis, the engine cooling system is abnormal. For example, the common water temperature sensor, radiator, water pump and other important parts can not play their role for some reason, which is prone to engine boiling failure, which is why the boiling failure does not necessarily occur in summer.


How to deal with it after boiling?

The engine boiling fault is very urgent, which leads many novices to lack rich handling experience. If they are stunned on the spot, it's OK. If they are not handled properly, they will be scalded or disfigured! Therefore, we must avoid the following wrong operations!

1、 Shut down the engine immediately

After many friends encounter the engine boiling fault, the first idea is to stop the engine immediately, immediately and quickly. Does the engine stop running mean that the fault is solved immediately? No!

Because only when the temperature in the engine cylinder rises rapidly will the boiling phenomenon occur, that is, at this time, the piston, piston ring, cylinder liner and other important components are in an ultra-high temperature state. If the engine is shut down immediately, the temperature can only be cooled gradually, but the piston rings and other components that originally expanded due to thermal expansion and cold contraction will have adhesion problems, resulting in the failure of the engine to work normally.

2、 Fill the engine with cold water ?

If the engine is boiling due to ultra-high temperature, a considerable number of friends must think that pouring cold water on the engine immediately can play a rapid cooling role. In addition, it is not difficult to take water from the construction site, so is this method that is fast, saves money and can solve the problem practical? The answer is no!

3、 Open the Radiator water tank cap

If pouring cold water directly doesn't work, is it feasible to add cold water to the water tank after boiling? Can this method avoid engine deformation and safety accidents? The answer is no!

Although this method is theoretically feasible, in fact, ultra-high temperature will directly cause the water in the water tank to boil. If the driver opens the water tank cover rashly at this time, he is likely to be scalded by a large amount of water vapor and splashed boiling water.

4、 Pour coolant on the radiator

Since the risk factors of the above simple methods are relatively large, pouring coolant on the radiator is always an effective method, isn't it? NEVER do that!!!

This is because the water temperature of the radiator is particularly high, accompanied by water vapor. If the coolant is directly added at this time, the liquid will produce a large amount of water vapor when heated, and the pressure will rise instantaneously, resulting in the rapid ejection of boiling water and steam, which is likely to cause facial burns and even disfigurement!


These are the methods that most of you will take when you encounter the engine boiling fault. I believe you can clearly know that no matter which method has a great impact on the machine and personal safety through the introduction of this article
