A fully functional air conditioning system is essential for driver well-being and productivity, especially during long hauls in extreme weather. The WG1642828102 Air conditioning assembly from HOWO is a complete, factory‑matched HVAC solution, integrating the condenser, evaporator, expansion valve, and blower into a single, precision‑engineered unit. As a comprehensive Howo/Sitrak truck parts offering, this assembly is designed to deliver rapid cabin cooling, efficient dehumidification, and quiet operation, ensuring a comfortable environment for drivers and passengers alike. Manufactured from high‑grade aluminum and corrosion‑resistant materials, the WG1642828102 is built to withstand the rigors of heavy‑duty trucking, offering a direct, plug‑and‑play replacement that restores the original cooling performance of your HOWO vehicle. Whether you are upgrading an aging system or replacing a failed unit, this air conditioning assembly guarantees consistent, reliable comfort in any climate, making it the definitive choice for professional workshops and fleet maintenance teams.
The WG1642828102 Air conditioning assembly is not a collection of separate parts – it is a fully integrated, engineered system that manages the entire refrigeration cycle from compression to evaporation. It includes a high‑efficiency condenser that rejects heat to the outside air, an evaporator that absorbs heat from the cabin, a thermostatic expansion valve that precisely controls refrigerant flow, and a powerful blower fan that circulates cooled, dehumidified air. HOWO has designed this assembly with optimized component matching, ensuring that each part works in perfect harmony to deliver maximum cooling capacity and energy efficiency. The use of parallel‑flow technology in the condenser and multi‑louver fins in the evaporator enhances heat exchange by up to 25% compared to conventional designs, resulting in faster pulldown times and lower compressor load. With the WG1642828102, you benefit from a system that cools quickly, runs quietly, and maintains consistent temperature, even when the outside thermometer soars.

The WG1642828102 is engineered as a complete thermal management system, with each component carefully matched to optimize overall performance. The condenser uses a parallel‑flow, micro‑channel design that maximizes the surface area for heat rejection, while the evaporator features a multi‑louver fin geometry that promotes turbulent airflow for superior heat absorption. The expansion valve is factory‑calibrated to maintain the ideal superheat, ensuring that the evaporator operates at peak efficiency without the risk of liquid slugging.
The blower motor is dynamically balanced and equipped with a forward‑curved centrifugal fan, delivering high static pressure to overcome duct resistance, even at low speeds. The housing is injection‑molded from a glass‑filled polypropylene blend that offers excellent dimensional stability and acoustic damping. All refrigerant connections use automotive‑grade O‑rings and are leak‑tested at the factory using helium mass spectrometry. Every WG1642828102 is subjected to a full functional test, simulating real‑world ambient conditions to verify cooling capacity, noise levels, and electrical integrity. This meticulous attention to detail guarantees that the assembly delivers consistent, quiet, and powerful cooling for the life of your vehicle.
The WG1642828102 is specifically designed for HOWO heavy‑duty trucks, including the T7H, A7, and derivative models equipped with the factory HVAC system. It mounts directly into the dashboard or under‑dash cavity, with factory‑specified mounting points and electrical connectors, ensuring a straightforward plug‑and‑play replacement. The duct connections and refrigerant line interfaces are identical to the original unit, eliminating the need for custom brackets or hose adaptations.
This assembly is also compatible with many Sinotruk and other commercial vehicles that share the same cabin architecture. To confirm fitment, always verify the OEM number on your existing unit. If it matches WG1642828102, this component will integrate seamlessly. Keeping this assembly in your spare parts inventory enables rapid AC restoration, reducing driver discomfort and minimising downtime during peak summer months.

Replacing a worn or underperforming AC unit with the WG1642828102 delivers a significant improvement in cabin comfort. The matched components ensure that the system operates at its designed coefficient of performance (COP), reducing the time required to cool the cabin and maintaining stable temperatures even during prolonged idling. The improved airflow from the high‑efficiency blower reaches all zones evenly, eliminating hot spots and ensuring that drivers remain alert and focused.
The energy efficiency of the assembly reduces the load on the engine, translating to modest fuel savings over time, especially in hot climates where AC usage is constant. The robust construction and corrosion‑resistant materials also extend the service life of the system, reducing the frequency of repairs. For fleet operators, a reliable AC unit reduces driver complaints and improves retention, while also protecting sensitive electronic equipment from heat‑related failure. Investing in the WG1642828102 ensures that your drivers stay comfortable, productive, and safe in any weather.
Installing the WG1642828102 Air conditioning assembly is a task best performed by an experienced HVAC technician. Begin by safely recovering the refrigerant from the existing system. Remove the dashboard panels, glove box, and any covers that obstruct access to the old assembly. Disconnect the refrigerant lines, electrical connectors, and drain hoses.
Carefully remove the old unit and inspect the ducting for debris or damage. Install the new assembly, ensuring that all mounting points align correctly. Replace all O‑rings and gaskets with new ones lubricated with PAG oil. Reconnect the refrigerant lines, electrical wiring, and drain tubes. Before recharging, evacuate the system for at least 30 minutes to remove moisture and air. Recharge with the specified refrigerant quantity and check for leaks using an electronic detector. Reassemble the dashboard and test all functions. With proper installation, the WG1642828102 will provide years of reliable cooling comfort.
Pro Tip: When replacing the entire assembly, it is highly recommended to also replace the receiver‑drier and expansion valve (if not included) to prevent any contaminants from damaging the new system. The WG1642828102 is designed to work with fresh supporting components for optimal longevity.
Genuine HOWO components are engineered to the highest standards, and the WG1642828102 Air conditioning assembly is no exception. Aftermarket units often use mismatched components, lower‑grade aluminum, or substandard blower motors, resulting in poor cooling, high noise, and early failure. HOWO’s assembly is manufactured using the same materials and specifications as the original equipment, guaranteeing a perfect fit and reliable performance.
By choosing the WG1642828102, you benefit from HOWO’s rigorous testing, including thermal performance validation, vibration endurance, and salt spray corrosion testing. This ensures that the assembly can withstand the extreme conditions of heavy‑duty trucking. Moreover, genuine parts are backed by a comprehensive warranty and supported by HOWO’s global technical network, giving you confidence in your purchase and long‑term peace of mind.
