The Water Temperature Is High. Don'T Rush To Replace Thermostat.

In the hot summer, I believe many brothers have encountered the problem of high engine water temperature. In addition to the common radiator blockage and fan clutch damage, another small part of our engine can not be ignored, which is the thermostat.

The function of the thermostat is to automatically adjust the amount of water entering the radiator according to the level of coolant, and adjust the heat dissipation power of the engine cooling system to control the temperature of the engine within the best working range . In short, it is a small component that keeps the cooling water temperature of the engine relatively constant. Its normality is also directly related to the temperature of our engine.

It is normal that the water temperature will rise to a certain extent during the normal operation of the thermostat and the heavy load operation stage of the engine such as climbing. Once it reaches the level road, the water temperature will soon return to normal.
However, some brothers may encounter this situation. The water temperature is normal when there is a small load on the flat road, but the water temperature will soar with a little load, and the cooling time is relatively long after returning to the flat road.

Touch the temperature of the upper and lower water pipes of the radiator by hand. In this case, it is easy to misjudge the fault. It is considered that the fan clutch is broken or the radiator is blocked. After cleaning and replacing the parts, the problem remains . In this case, it may be caused by the thermostat card issuing phenomenon. Therefore, after the above phenomena occur in the vehicle, it can be considered to check the first.

The inspection method is also very simple. Remove the thermostat from the car, put it into the pot and boil it, and observe whether the thermostat opens with the rise of water temperature and whether there is hairpin in the middle. If the thermostat in your car closes the small cycle through skirt movement, such as Dongfeng DCI engine, in addition to checking whether the thermostat is jammed, it is also necessary to check whether the casing on the first water pump is jammed due to foreign matters.
It’s not easy for us to drive a truck. After all, the vehicle is composed of N parts, which will inevitably lead to some problems. However, we should not blindly replace the parts after the problems occur. We should find the root cause of the problems and apply the medicine to the case. We have to solve the problems with the least money.
