The thermostat automatically adjusts the amount of water flowing through the radiator according to the change of the water temperature of the engine cooling system. During long-term use, the thermostat sometimes fails, causing the engine to overheat or overcool, causing the power to drop and the fuel consumption to increase. Therefore, it is on the way You can do inspection and maintenance work at any time to improve the service life of the economizer.
After starting the engine, check: open radiator radiator cover, if the radiator cooling is quiet, indicating that the thermostat is working properly, otherwise the thermostat is working abnormally, because when the water temperature is below 70 degrees, the thermostat The expansion tube is in a contracted state and the main valve is closed; when the water temperature is higher than 80 degrees, the expansion tube expands, the main valve gradually opens, the circulating water in the radiator begins to flow, and the water temperature is warm; indicating that the main valve of the thermostat is not closed tightly, so that the cooling Water is circulating too early.
Inspection after rising water temperature: At the beginning of the engine work, the water temperature rises quickly: When the water temperature indicator shows 80 degrees, the heating rate slows down, indicating that the thermostat is working properly. Conversely, if the water temperature rises rapidly, the internal pressure When it reaches a certain level, boiling water suddenly overflows, indicating that the main valve is stuck. When the water temperature gauge shows 70-80 degrees, open the radiator cover and the radiator drain switch. If the water temperature is hot, feel that the thermostat is working properly; if the radiator water temperature is low, and the radiator water inlet There is less water flow out or out of the water pipe, indicating that the thermostat main valve cannot be opened.
There are different opinions about the origin of tea drinking in Zhong country: some people think that it originated in ancient times, others think that it originated in Zhou, Qin and Han Dynasty, Three Kingdoms, Northern and Southern Dynasties and Tang Dynasty. The main reason for the divergence of opinions is that there was no word "tea" before Tang Dynasty, but only the word "tea" was recorded. Until Lu Yu, the author of the Tea Sutra, the word "tea" was written in one picture. Tea ", so there is a saying that tea originated in the Tang Dynasty. Others are still said to have originated from Shennong and Qin and Han dynasties.
