OEM WG9918580087 • High-Altitude Version • Sealed connector • Vibration resistant • Direct OEM fit
The WG9918580087 Independent Heater Sensor (High-Altitude Version) is a critical temperature sensing component in the chassis fuel heating system of SINOTRUK Howo trucks. It monitors the temperature of the independent heater or fuel circuit, sending a precise electrical signal to the heater controller to regulate heating output at high altitudes where temperature and pressure conditions differ from lowland operation.
This WG9918580087 sensor is precision-manufactured to exact OEM dimensions. The sensing probe is made from corrosion-resistant metal, the housing is molded from heat-resistant engineering plastic, and the connector matches the factory harness plug exactly. The unit is tested for correct resistance curve and stable signal output across the full operating temperature range.
Common signs that an independent heater sensor needs replacement include a heater that fails to activate, incorrect heater output, engine warning lamps, fault codes for temperature sensor signal, and visible damage to the probe or connector. Fitting a new WG9918580087 sensor restores accurate temperature measurement and reliable heater control at altitude.
Whether you are repairing a faulty heater circuit, replacing a damaged sensor or carrying out preventive maintenance on a fleet of Howo trucks, the WG9918580087 Independent Heater Sensor delivers the quality, reliability and durability that SINOTRUK Howo professionals expect.
The WG9918580087 Independent Heater Sensor (High-Altitude Version) is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it threads into the original sensor port and connects to the factory heater harness without modification.
This sensor is essential in applications where reliable fuel heater operation and cold-weather starting are critical at high elevations, such as long-haul transport, construction and mining in mountainous regions. In these duties, the sensor must maintain accurate temperature signal output and resist vibration, fuel exposure, heat and contamination.
When replacing the independent heater sensor, it is recommended to inspect the heater element, controller, wiring harness, fuse and relay for wear or damage. The WG9918580087 is designed to work with the factory fuel heating system, ensuring correct signal timing and reliable operation.
For fleets with multiple HOWO trucks, standardising on the WG9918580087 Independent Heater Sensor simplifies electrical repair inventory and ensures the correct sensor is available for scheduled maintenance or emergency repairs.
Replacing the WG9918580087 Independent Heater Sensor is a simple procedure that requires basic electrical and mechanical knowledge. This work should be performed by a qualified technician. Begin by disconnecting the battery negative terminal to prevent accidental short circuits.
Locate the sensor on the independent heater or fuel circuit. Disconnect the electrical connector from the old sensor, noting the locking tab orientation. Unscrew the sensor from its port or release the retaining clip and withdraw it. Inspect the probe and connector pins for corrosion or damage.
Fit the new WG9918580087 sensor into the port and tighten it to the correct torque. Reconnect the electrical connector until it clicks into place. Reconnect the battery and clear any fault codes using a diagnostic tool. Test the heater system through its full operating range to confirm correct sensor output.
For ongoing maintenance, periodically check that the sensor is securely mounted and that the connector and probe are free from damage or contamination. If heater operation becomes erratic, inspect the heater element and controller before replacing the sensor again.
The WG9918580087 Independent Heater Sensor is manufactured in an ISO 9001-certified facility using high-grade engineering plastics and precision sensing elements. Raw materials are sourced from certified suppliers and undergo incoming inspection for electrical characteristics, dimensional accuracy and seal integrity.
Each sensor is assembled on precision lines and then tested for resistance curve accuracy, insulation resistance and connector retention. The housing is inspected for correct fit and finish, and the probe is checked for straightness and surface condition. Every unit is subjected to a functional temperature test before packing.
Random samples from each production batch undergo environmental testing, including thermal cycling, humidity exposure, vibration and salt spray, to validate long-term reliability in heavy-duty truck applications. These tests ensure the sensor continues to perform in the harsh conditions experienced by SINOTRUK Howo vehicles.
We back the WG9918580087 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every independent heater sensor delivers the same fit, function and durability as the original factory component.
The WG9918580087 Independent Heater Sensor (High-Altitude Version) is a vital component for maintaining reliable fuel heater operation, cold-weather starting and engine protection on your Howo truck operating at high elevations. A faulty sensor causes heater failure, fuel waxing and difficult starts, especially in cold mountain conditions.
Manufactured from high-quality materials with a sealed connector and corrosion-resistant probe, the WG9918580087 offers outstanding reliability, temperature accuracy and long-term durability. Its direct-fit design ensures straightforward installation and immediate compatibility with the factory fuel heating system.
Fleet operators benefit from reduced cold-start downtime, lower maintenance costs and improved vehicle availability in mountainous regions. Owner-operators gain peace of mind knowing their independent heater is monitored by a sensor that meets strict OEM standards and is backed by a comprehensive warranty.
