Function:The function of the thermostat is to keep the engine from overcooling. For example, after the engine is working normally, the temperature of the engine may be too low if there is no thermostat when it is driven in winter. At this time, the engine needs to temporarily stop water non-circulation to ensure that the engine temperature is not too low.
