Yuchai YC6108G what is the cause of the high water temperature of the engine and how to solve it

Hello, there are many reasons for high water temperature, such as the thermostat cannot be opened, the water pump is damaged, the lack of antifreeze, the cooling fan is damaged, the engine cylinder gasket is damaged, etc., the specific reason is recommended to go to the repair shop for inspection.

The high water temperature of Yuchai engine may be caused by the fault code of some components. There is also a possibility that the car engine is not maintained in time and is not maintained regularly, so the water temperature will be high during the operation of the engine.

If the engine is not maintained in time, the water tank lacks too much water, or the water is discharged, and when the water is too full, the air in the engine is not completely discharged after the water is too full, which will cause air resistance. This phenomenon only requires adding water in time to let the engine run for a few more minutes, at which point it is enough to open the water filling cap and fill it up again.

When the water temperature is too high, you only need to adjust the distributor and delay the ignition time appropriately. Sometimes the water temperature is too high due to the failure of the part. When the idle speed of the air conditioner is relatively low, it will also cause the water temperature to be high, and when the idle speed of the air conditioner is increased, you should check whether the equipment is operating normally in time.

It is recommended to find out the reasons from the following aspects:

1. Relatively simple, first confirm whether the lower engine is connected to the radiator pipeline is blocked; Poor circulation can easily lead to high water temperature failure when the engine climbs;

2. Furthermore, disassemble the engine water outlet, remove the thermostat to see if it can work normally (soak the thermostat in boiling water to see if it can be opened normally), if the thermostat fails, it will also lead to high water temperature;

3. Disassemble the oil cooler or water pump to see if there is rust and debris in the engine cavity, there was once a customer in Shanxi who added the cooler is not clean, there are impurities that cause the engine cavity to rust, and the water temperature is high due to debris blockage (this situation is generally more serious, the water temperature is high when the engine works for a period of time, and it has not been able to come down).

4. If the whole vehicle is mainly running in the south with a full load, it is recommended to replace a 65° open thermostat.

The water temperature of the diesel engine engine is high, and the thermostat can only be removed. The reason for the high water temperature may be that the cylinder gasket is flushed, the water tank is dirty, the antifreeze is missing, and the fan does not turn. There is a problem with the water pump.

Question: The cylinder head gasket is not flushed, the water tank and water pump are all new, the water is full, the fan is also turning, the thermostat is also removed, and the water temperature is still high.

If you can't find the problem, you can only add another auxiliary water tank to the vehicle. Because if these things are okay, these are all the things that include heat dissipation, and you haven't found the problem, you can only say that there is a problem with the engine itself.

Question: There is also a secondary water tank with enough oil.

Answer: Adding a secondary water tank is to add a water tank like the original car, and then add a fan. It is not the sub-tank of the backwater. Because by adding a secondary tank like this, he multiplied the amount of heat dissipated by two.

The heat dissipation will be better. Another solution is to add water to the tank, but this is more complicated.

1. There 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. 2. Pull over, but don't turn off the engine immediately! 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).

3. Of course, if it is an electric water pump engine, it will be better), too high temperature can not be cooled, and 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. 4. Check whether the antifreeze is lacking, resulting in high engine water temperature.

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.

My Yuchai engine, high temperature, I don't know why.

There is too much dust in the radiator of the water tank, the inside of the water tank needs to be cleaned, whether the thermostat is normal, and the water pump belt is loose

Summary. Hello, after the water temperature of this engine is high, you should park the car in a safe area, and then idle for 3 5 minutes, and wait for the water temperature to gradually drop, and then turn off the car to avoid sticking to the cylinder. After turning off the ignition, check for any lack of antifreeze and any damage to the fan, water pump and thermostat.

There is no problem in these places, it is due to the high temperature caused by the excessive load of the engine, you can cool the car, listen to the sound when starting the car, there is no knocking sound, or the power is normal, there is no problem in these places, you can open it first, and the high temperature situation occurs again, replace the thermostat and check the sealing of the cylinder gasket.

What to do if the water temperature of Yuchai 4108 engine is high.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Problems with all parts of the engine cooling system and antifreeze may cause high engine water temperature alarms, and it is best to go to the nearest maintenance station to check it.
