This brand-new cooling water temperature sensor is a key spare part for diesel engines. It monitors real-time changes of engine coolant temperature and feeds accurate data back to the control instrument. It helps users grasp engine running temperature in time, effectively prevent overheating faults and protect internal engine components. Made of durable temperature-resistant materials with excellent sealing performance, it resists long-term liquid erosion and temperature fluctuation, maintaining stable working performance for daily mechanical operation.
