The water temperature of the Doosan excavator engine is high, and the causes that may lead to the failure are analyzed
The radiator vents are clogged with dust and poor heat dissipation.
The fan belt is loose and the heat dissipation is poor.
The thermostat cannot be opened, and the coolant is circulated in a small way.
The water temperature sensing plug is faulty.
Doosan 225-9 Excavator Engine High Water Temperature Fault Inspection Steps and Solution Steps.
Check that the coolant level is normal and the water tank cover is good;
Check that the fan belt is not loose;
Check the water induction plug, its resistance value is normal; The opening range of the thermostat is normal; When the radiator lower guard was opened, it was found that the hose from the radiator to the water pump was suddenly flattened when the engine was running at high speed, resulting in poor coolant circulation.
Cause of failure: The water pipe becomes soft after high temperature.
Troubleshooting: Repair or replace water pipes.
Doosan excavator engine water temperature is high, what causes this?

The water temperature of the Doosan excavator engine is high, and the causes that may lead to the failure are analyzed: The air vent of the cooling bucket shaker is blocked by dust, and the heat dissipation is poor, and the fan air flush belt is loose, and the heat dissipation is poor, and the thermostat cannot be opened, and the coolant circulates in a small way, and the water temperature sensing plug is faulty. Doosan 225-9 excavator hair hole accompaniment motor water temperature high fault inspection steps and solution steps Check that the coolant level is normal and the water tank cover is good; Check that the fan belt is not loose; Check the water induction plug, its resistance value is normal; The opening range of the thermostat is normal; Open the lower guard plate of the radiator, and find that the hose from the radiator to the water pump was suddenly flattened when the engine was running at high speed, resulting in poor coolant circulation
Failure solution for water pipes to become soft after high temperatures: repair or replace water pipes.

Hello, happy to answer your <>
The reason for the high water temperature of the Doosan excavator engine is 1Problems with the cooling system: the radiator is blocked, the fan does not rotate, the water pump does not run properly, etc., resulting in the coolant cannot be circulated normally, which causes the engine water temperature to rise.
2.Wear and tear on engine components: Cooling pipes, pump seals, and water tanks that cause coolant leaks can also cause water temperatures to rise continuously.
3.Engine overload work: For excavators, long-term overload work requires continuous power output, which will produce relatively high operating temperatures and aggravate engine failures.

Hello, mine is the Doosan 220 excavator, the water temperature has been high since noon yesterday, and the work at night is also high, and the water comes out of the water tank, what is the situation?
Kiss <>
Hello. The reason is that the cooling system is blocked: due to the improper use of the inner wall of the cooling system for a long time, there are impurities in the coolant, and the pipes and radiators are blocked and loopholes.
Perform thorough cleaning and maintenance of the cooling system. Radiator failure: Due to the corrosion and aging of the radiator and the damage caused by external pressure, the radiator cannot work normally, which affects the cooling effect.
Cleaning the water tank?

The glass lift relay is located under the driver's co-pilot's seat. Lift the plastic cover on the front of the driver's and co-pilot's seats, and you'll see a black relay box that contains various relays for glass lifting.
Kiss <>
Yes, the tank should be cleaned.
What glass lifter, mine is Doosan excavator with high water temperature.
Kiss <>
The teacher told you to clean the water tank.

Expansion: An engine, also known as an engine, is a machine that can convert other forms of energy into another type of energy, usually chemical energy into mechanical energy. The engine is the power of the car, is an important part of the car, the engine and gearbox chassis is also known as the three major parts of the car.

Anonymous users2024-02-09There are many reasons for the high water temperature of the engine or even "boiling", such as damage to the electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the radiator, insufficient coolant, etc.
Pull over, but don't turn off the engine right away! Because the coolant temperature is already high and the cooling capacity has reached its limit, if the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft).
Of course, if it is an electric water pump engine, it will be better), too high temperature is not cooled, the engine is also unbearable. If the engine is left idle for a while, the constant circulation of coolant can still reduce the impact of high temperatures on the engine.
Check for a lack of antifreeze that is causing high engine water temperatures. The circulation of the coolant, whether the circulation is not smooth. Secondly, you can also check that water temperature sensors, water pumps, thermostats, cooling fans, etc., may cause high water temperatures.
If you don't have a strong hands-on ability, you should go to the repair shop for an inspection.
We design, manufacture and produce excavators from the customer's point of view, and when the excavator works, continuous inspection and maintenance, so that our excavator is always strong, and our users can always be satisfied. >>>More
Excavator industry is not know how to operate the excavator, you can go to work to get a salary, imagine which boss dares to teach hundreds of thousands or even millions of excavators to a driver who is not very skilled and inexperienced? So many people who went to school couldn't work at all, but spent thousands of yuan or even more than 10,000 yuan to buy a useless operation certificate! The real working site of the excavator is not as narrow and flat as the school, and you can run to the place where the excavator works to see what kind of environment the excavator is working in, so don't hold it for a month or two to learn to find a job! >>>More
Due to the particularity of its structure and the diversity of on-site conditions, the slewing bearing of the excavator is prone to the failure of slewing bearing, slewing ring gear or slewing motor damage due to oil leakage, so the leakage should be prevented and dealt with in time. >>>More
1) The sealing ring of the center rotary joint is damaged
The central rotary joint is composed of two major parts, the housing and the mandrel, the mandrel is installed on the lower car body, the housing is installed on the upper car body, and the mandrel has an annular groove equal to the oil pipe. The hydraulic oil from the main valve core flows to the motor through the vertical hole in the mandrel through the housing, and the housing rotates continuously with the upper car body, and the groove on the mandrel can also be kept smooth with the oil port on the housing, and the hydraulic oil can enter and exit freely on the central joint. If the filter element of the hydraulic oil is not replaced in time, the bypass valve on the filter element may be opened, and the impurities in the oil are not filtered so that the impurities in the oil directly enter the sliding surface of the central rotary joint, so that the sealing ring on it is damaged, and the speed of the walking motor on both sides is not the same due to the pressure oil leakage on one side of the excavator when walking, and the excavator is caused to deviate from walking. >>>More
Don't buy Doosan excavators, I regret buying them, I am an old driver who has been driving excavators for more than 10 years, and now I am the owner, Doosan's service is too poor, and the quality of the whole machine is not as good as before, everyone says that the current Doosan is not the previous Daewoo, and there are often a large number of excavators appearing, and the big arm is cracked. Cracking of the chassis. Lever handle oil leaking. >>>More
