When buying a car, everyone will refer to various configurations, mainly the appearance, interior decoration, engine and so on. For some details of the car, people who know a little about the car will also check it, but those who don't know the car can only buy it back and find it slowly. Take the car for example. There are still a lot of data to observe after starting the car, Water temperature is one of the most commonly mentioned indicators. We can know the general working condition of the car engine in advance from the car water temperature, but inexperienced novices may not understand the function of the car water temperature gauge. Is the car water temperature gauge useful? How should we look at the water temperature of a car without a water temperature gauge?

The stroke of the water temperature gauge is 0-130℃, and the normal temperature is 90℃ in the middle. The temperature rises rapidly after the car starts. After the gauge needle reaches the middle part, the water temperature will not rise. Generally speaking, the temperature develops best when it is in the middle part. Generally speaking, the abnormal key of refrigeration system includes liquid leakage, insufficient coolant, common faults of fan and common faults of circulating pump. The maximum ignition temperature of automobile engine under heavy load exceeds 2000 ℃, and it also needs to exceed 1000 ℃ under small load and waiting speed. There must be this temperature in the cylinder to improve the thermal efficiency of the automobile engine; The cylinder liner, piston rod and cylinder head cannot bear too high temperature.

Generally, the automobile water temperature gauge is marked with two English letters C and h, or distinguished by white and red areas. C stands for cold and H stands for hot. If the water temperature gauge approaches h or red dangerous area and the water temperature alarm light is on in serious cases, it means that the engine coolant is too high.

In this case, the wear of various parts will increase. If it is not handled properly immediately, the engine may burn and affect the serious engine damage accident. Low engine water temperature also has disadvantages, resulting in insufficient combustion of engine mixture, reduced power, poor lubrication and excessive emissions.
