When the original thermostat assembly fails, typical problems include slow heating of vehicle heater, excessively high fuel consumption, coolant leakage from the housing joint, and sudden overheating of engine water temperature. Each finished product undergoes sealing pressure leakage test and precise temperature opening calibration before leaving the factory. All water pipe interfaces, fixing hole positions and sensor reserved positions are completely consistent with the original parts, enabling direct bolt-on installation without cutting or modification.
