The Radiator is a premium, heavy-duty chassis engine cooling component engineered specifically for SINOTRUK Howo trucks, delivering reliable heat dissipation and maintaining optimal engine temperature under the most demanding operating conditions. As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM-grade radiator as a direct replacement for the original factory unit. The WG9719530277 radiator ensures efficient coolant flow, prevents overheating and protects the engine from thermal damage during long hauls, heavy loads and extreme ambient temperatures.
Manufactured from high-strength aluminium or copper-brass with a precision-brazed core, reinforced tanks and a durable corrosion-resistant coating, the Radiator is built to exact OEM dimensions. Its robust construction maintains correct cooling capacity, resists pressure cycling and vibration, and provides dependable performance on Howo A7, T7H and related heavy-duty models.
OEM WG9719530277 • High-efficiency cooling • Corrosion resistant • Direct OEM fit • Reliable heat dissipation
The WG9719530277 Radiator is a critical component in the cooling system of SINOTRUK Howo trucks. It transfers heat from the engine coolant to the ambient air, maintaining the engine at its optimal operating temperature. Without a properly functioning radiator, the engine can overheat, leading to power loss, warped cylinder heads, damaged pistons and costly repairs.
This WG9719530277 radiator is precision-manufactured to exact OEM dimensions. The core features a high-density fin design for maximum heat transfer, the tanks are reinforced for pressure resistance, and the inlet and outlet ports match the factory hoses. The unit is pressure-tested to ensure leak-free performance.
Common signs that a radiator needs replacement include coolant leaks, overheating, frequent coolant top-ups, a clogged or damaged core, and visible cracks or corrosion on the tanks. Fitting a new WG9719530277 radiator restores proper cooling and protects the engine from thermal damage.
Whether you are repairing an overheating engine, replacing a damaged radiator or carrying out preventive maintenance on a fleet of Howo trucks, the WG9719530277 Radiator delivers the quality, cooling efficiency and durability that SINOTRUK Howo professionals expect.
The WG9719530277 Radiator is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series that use the standard engine cooling system. It is a direct OE replacement, so it fits the factory radiator frame, hoses and fan shroud without modification.
This radiator is essential in applications where reliable engine cooling directly affects performance and durability, such as long-haul transport, construction, mining and municipal service. In these duties, the radiator must dissipate heat efficiently, resist pressure and vibration, and maintain consistent coolant flow.
When replacing the radiator, it is recommended to inspect the water pump, thermostat, cooling fan, hoses and coolant for wear or contamination. The WG9719530277 is designed to work with the factory cooling system components, ensuring proper sealing and reliable operation. It is suitable for both standard and heavy-duty cooling configurations.
For fleets with multiple HOWO trucks, standardising on the WG9719530277 simplifies cooling system maintenance inventory and ensures the correct radiator is available for scheduled service or emergency replacement.
Replacing the WG9719530277 Radiator is a moderately complex procedure that requires mechanical expertise and appropriate tools. This work should be performed by qualified technicians with experience in heavy-duty cooling systems. Begin by parking the vehicle on level ground and allowing the engine to cool completely.
Drain the coolant into a suitable container and disconnect the hoses, fan shroud and electrical connections from the old radiator. Remove the mounting bolts and carefully lift the radiator out of the frame. Inspect the frame, hoses and fan for wear or damage before installing the new unit.
Position the new WG9719530277 radiator in the frame and secure it with the mounting bolts. Reconnect the hoses, fan shroud and electrical connections. Fill the system with the correct coolant mixture and bleed any air from the system. Check for leaks at all connections.
Start the engine and allow it to reach operating temperature. Check that the cooling fan engages and that the temperature gauge reads normally. Inspect for leaks and top up the coolant if necessary. For ongoing maintenance, check the coolant level and condition regularly, and clean the radiator fins to maintain airflow.
The WG9719530277 Radiator is manufactured in an ISO 9001-certified facility using advanced brazing, assembly and testing processes. Raw materials are sourced from certified suppliers and tested for thermal conductivity, pressure resistance and corrosion resistance before production.
Each radiator is precision-built to exact OEM dimensions. The core is checked for fin density and tube alignment, the tanks are inspected for strength and sealing, and the inlet and outlet ports are verified for correct fit. Every unit is pressure-tested for leaks.
Random samples from each production batch undergo thermal cycling, burst pressure testing and salt-spray testing to validate long-term reliability under real-world conditions. These tests ensure the WG9719530277 continues to deliver efficient cooling throughout its service life.
We back the WG9719530277 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every radiator delivers the same fit, cooling capacity and durability as the original factory component.
The WG9719530277 Radiator is a vital component for maintaining the performance, efficiency and reliability of your Howo truck’s engine. A clogged or leaking radiator causes overheating, power loss and expensive engine damage. Replacing it with this genuine OEM-grade radiator restores proper cooling and protects the engine.
Manufactured from high-strength materials with a high-density fin core and reinforced tanks, the WG9719530277 offers outstanding cooling efficiency, pressure resistance and long-term durability. Its exact OEM fit ensures straightforward installation and reliable operation.
Fleet operators benefit from reduced engine downtime, lower maintenance costs and improved vehicle reliability. Owner-operators gain peace of mind knowing their engine is protected by a radiator that meets strict OEM standards and is backed by a comprehensive warranty.
