What is the reason why the water temperature of Weichai WD615 diesel engine for loader is too high

Some people think that if you remove the lid of the tank, the temperature of the water will decrease, but in fact, after the lid of the tank is removed, the water temperature will be higher because there will be less and less water.

See if the thermostat is broken, and if the thermostat is broken, the water temperature will be very high.

There is also to see if the heat dissipation of the water tank is good, because the conditions of the loader working are relatively bad, so sometimes the water tank will be blocked by some impurities, I am talking about the outside of the water tank, not the inside.

If there is anything you don't understand, you can q me 448798731 add a note (loader).

The temperature below 90 is normal, and now the temperature of the car is high, which lies in the role of the [thermostat], generally the current car factory is adjusted to 85 degrees, which means that the water temperature is 85 degrees, and the thermostat will open the cycle. For example, this is the reason why the warm air is very effective in winter. It's also summer, and it's normal, and it's okay if you don't boil the pot.

First of all, the two small water pipes of the air pump are broken, see if it is high, or it is not high, that is, the cylinder gasket of the air pump is pierced, if the cylinder gasket is sure that there is no problem, then look at the injector connecting piece and sleeve to see if there is any problem, and then there is a small waterway behind the pump.

Go to the mechanical encyclopedia of "My Second-hand Construction Machinery Network" to take a look.

1. The valve clearance is too small, and the car is not closed tightly as soon as it is hot.

2. The quality of the added engine oil is not good, and the engine is weak due to low oil pressure and poor lubrication.

3. The specific gravity of fuel is low, and the volatilization is fast and not easy to enter the cylinder.

When the diesel engine is not energetic to climb or under heavy load, the water temperature will be high! School oil pump is recommended!

Sooner or later, the oil supply time will lead to fatigue and high water temperature.

If it's an old car, it's an old car, it's boring, clean the water tank.

1. Cause the water temperature of the engine to be too high even"Bring to a boil"There are many reasons, 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.
