Jinbei Great Wall GM Water Temperature Sensor L1161/93184580/90411977, Domestic Quality Replacement

Jinbei/Great Wall water temperature sensor L1161/93184580/90411977 as domestic substitute, installed in radiator or coolant loop. Monitors coolant temperature in real time and transmits to ECU to control injection, ignition timing, and cooling fan operation for optimal engine temperature. Fits Jinbei, Great Wall and some common models; easy installation; estimated time 0.5 hours and requires draining some coolant. If engine hard to start, rough idle, abnormal temp gauge fluctuations or fans running constantly, sensor aging is the cause; replacement restores performance.
