Thermostat is to save energy consumption, because its specific function is to keep the temperature in the car closed before reaching normal temperature, so the water of this engine can only circulate in the upper part of the water tank, which can make the engine heat up quickly, because it consumes a lot of oil, which is the most harmful to the car at low temperature, and then it can be opened after exceeding normal temperature, so that water can circulate in the whole water tank and dissipate heat quickly. This is basically the function of the thermostat.
In the past summer, many people removed the thermostat, but it was wrong to do so, because if there was no thermostat to control the circulation range and speed of water, the water temperature would be very low at high speed, and the car would remain low all the time, which would increase fuel consumption and have a certain impact on the car for a long time.
