Haval Cummins Water Temperature Sensor 13650-79J80 Replaces 0280130093 12639899

Haval H9, Great Wall Gun models, and Cummins engine vehicles use temperature sensor OEM 13650-79J80, also compatible with 0280130093 and 12639899. This replacement uses high-temperature engineering plastic housing and copper temperature probe; thermal response is identical to OEM, durable in tests. It monitors coolant temperature and sends signal to ECU to adjust fuel injection and ignition, ensuring engine runs at optimum. Installation should ensure proper interface matching and sealing.
