When the engine temperature is too high, the first reaction of many card friends is: there is a problem with the thermostat, quickly remove the thermostat! But is that really reasonable? Today, I’ll talk to you about whether the thermostat can be disassembled at will.
At present, most diesel engines use wax thermostat with stable working performance. When the temperature of the cooling water is lower than the rated temperature, it valve is closed, and the cooling water can only be circulated in the diesel engine for a small time, rather than through the water tank for a large time. This is to accelerate the rise of cooling water temperature, shorten the warm-up time and reduce the running time of diesel engine at low temperature.
When the water temperature of the diesel engine is found to be too high, if it is checked that there is no shortage of coolant and the liquid level in the water tank turns over, it indicates that the water pump works normally, and it is necessary to check whether it is invalid.
