The WG1664160500 Left Defroster Strip Assembly is a critical climate control component in the cab of SINOTRUK Howo trucks. It directs warm air from the HVAC system onto the left side of the windscreen, preventing fog, frost and ice build-up that can obscure the driver’s view.
This WG1664160500 assembly is precision-manufactured to exact OEM dimensions. The duct body is molded from heat-resistant engineering plastic, the outlet grille is designed for even air distribution, and the mounting tabs match the factory dashboard fixing points exactly.
Common signs that a defroster strip assembly needs replacement include reduced airflow to the windscreen, cracked or warped plastic, a loose or rattling fit, and persistent fogging on the left side of the glass. Fitting a new WG1664160500 unit restores correct airflow and clear driver visibility.
Whether you are repairing a faulty defroster outlet, replacing a damaged strip or carrying out preventive maintenance on a fleet of Howo trucks, the WG1664160500 Left Defroster Strip Assembly delivers the quality, reliability and durability that SINOTRUK Howo professionals expect.
The WG1664160500 Left Defroster Strip Assembly 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 clips into the factory dashboard and connects to the original HVAC ducting without modification.
This assembly is essential in applications where driver visibility and cabin comfort are critical, such as long-haul transport, construction, mining and municipal service. In these duties, the strip must maintain correct airflow direction and resist vibration, heat and UV exposure.
When replacing the defroster strip, it is recommended to inspect the HVAC ducting, blower motor, blend door and surrounding dashboard trim for wear or damage. The WG1664160500 is designed to work with the factory climate system, ensuring correct air volume and reliable defrosting.
For fleets with multiple HOWO trucks, standardising on the WG1664160500 Left Defroster Strip Assembly simplifies interior repair inventory and ensures the correct part is available for scheduled maintenance or emergency repairs.
Replacing the WG1664160500 Left Defroster Strip Assembly is a simple procedure that requires basic hand tools and care with dashboard trim. This work should be performed by a qualified technician. Begin by disconnecting the battery negative terminal as a safety precaution.
Locate the defroster strip on the left side of the dashboard. Gently release the retaining clips or remove the fixing screws, taking care not to damage the surrounding trim. Withdraw the old strip and inspect the duct connection for cracks or debris.
Position the new WG1664160500 strip into the dashboard opening, aligning the tabs with the factory fixing points. Press firmly until the clips engage, or refit the screws and tighten them evenly. Reconnect the battery and test the defroster airflow with the HVAC system running.
For ongoing maintenance, periodically check that the strip is securely mounted and that the outlet grille is free from dust or obstruction. If airflow becomes weak or uneven, inspect the HVAC ducting and blower before replacing the strip again.
The WG1664160500 Left Defroster Strip Assembly is manufactured in an ISO 9001-certified facility using high-grade engineering plastics and precision injection molding. Raw materials are sourced from certified suppliers and undergo incoming inspection for melt flow, heat deflection and colour consistency.
Each strip is molded on automated presses and then inspected for dimensional accuracy, surface finish and clip retention. The outlet grille is checked for correct slot width, and the mounting tabs are tested for fit against the OEM dashboard gauge. Every unit is visually inspected before packing.
Random samples from each production batch undergo environmental testing, including thermal cycling, humidity exposure and UV ageing, to validate long-term reliability in heavy-duty truck applications. These tests ensure the strip continues to perform in the harsh conditions experienced by SINOTRUK Howo vehicles.
