3582960050 Loader Thermo Sensor for Hitachi ZW370-G

The original temperature sensor 3582960050 is designed and used in conjunction with the Hitachi ZW370-G large wheel loader. This universal number is its part number, which is a key identifier to ensure accurate matching with the host electronic control unit (ECU) and wiring harness plug. This sensor is mainly used for real-time monitoring of engine coolant or hydraulic system oil temperature, and is the core component of the equipment thermal management system. It may also be applicable to models of the same series such as ZW370-5A and ZW370-7 that use the same control system, but it is strongly recommended to verify the specific model of the host and this universal number when ordering.

The main body of this product is a golden cylindrical metal shell, presumably made of copper or stainless steel material, with good thermal conductivity and corrosion resistance. The top is equipped with silver metal plug-in electrical connectors to ensure reliable connection. Its internal core is a negative temperature coefficient (NTC) thermistor, whose resistance value changes precisely with temperature, thereby converting temperature signals into electrical signals and transmitting them to the ECU. The product design is compact, the shell is sturdy, and can withstand the vibration, high temperature, and oil erosion of the loader under harsh working conditions. It has a wide working temperature range and sensitive response, providing key data support for engine overheating protection, fan control, and efficiency optimization.

It is recommended to check the electrical connection of the sensor for stability, looseness, or corrosion every 500 hours of work or during regular maintenance, and clean its surface of oil and impurities to ensure that the temperature sensing head is in full contact with the medium. If the dashboard displays abnormal temperature, alarm or unstable readings, after troubleshooting the cooling system, a multimeter should be used to check whether the sensor resistance value meets the standard curve. If it deviates, it needs to be replaced. When replacing, be sure to use original parts 3582960050. Before installation, apply an appropriate amount of sealant to the threaded part and tighten it to the specified torque to avoid excessive force damaging the housing. Keeping the coolant/hydraulic oil clean and the system leak free is the foundation for extending the service life of sensors.
