Heavy-duty radiator cooling fan assembly for SINOTRUK HOWO mining and construction trucks. OEM part number 800101409. Essential thermal management component in extreme-condition fleet maintenance.
SINOTRUK OEM-Compatible Fan Assembly – Model 800101409 | For HOWO Mining & Heavy-Haul Trucks
Ensure maximum engine cooling efficiency under extreme loads with this genuine-specification fan assembly (Part No. 800101409) , engineered specifically for SINOTRUK HOWO mining, dump, and off-road trucks such as the HOWO A7, T7H, ST1, and mining variants. Designed as a direct-fit replacement for original equipment, this robust radiator cooling fan plays a critical role in preventing overheating — making it one of the most essential Sinotruk spare parts in high-temperature, high-dust operating conditions.
Built with reinforced nylon composite blades (6-blade design) and a sealed viscous clutch or electric motor drive system, this fan delivers powerful airflow up to 35,000 CFM, ensuring rapid heat dissipation from the radiator core even when idling or climbing steep grades. The housing is corrosion-resistant and vibration-dampened to withstand constant shock loading typical in quarry, mine, and construction site operations.
This fan assembly is compatible with SINOTRUK WD615, MC05, MC07, and MC11 series engines, and integrates seamlessly into existing cooling systems without modification. It’s widely used by mining fleets across Africa, Southeast Asia, South America, and the Middle East where reliability and durability are non-negotiable.

How to Install the 800101409 Fan Assembly on SINOTRUK HOWO Mining Trucks:
Turn Off Engine & Disconnect Battery: Always disconnect the negative terminal before working on electrical systems.
Drain Coolant (Optional): If space is tight, partially drain coolant to avoid spills during radiator access.
Remove Grille & Shrouds: Unbolt front grille, shroud covers, and air ducts to access the radiator and fan unit.
Disconnect Wiring Harness: Locate the connector for the electric/viscous clutch fan motor and unplug it safely.
Loosen Fan Clutch Bolts (if applicable): For engine-driven fans, loosen the central retaining bolt using an impact wrench or fan tool to hold the pulley.
Remove Mounting Brackets: Unscrew side brackets securing the fan assembly to the radiator or water pump.
Extract Old Fan Unit (800101409): Carefully slide out the old fan, avoiding damage to radiator fins.
Install New Fan Assembly (800101409): Align the new heavy-duty fan with mounting points. Ensure proper clearance between blades and shroud.
Reconnect Electrical Plug or Clutch: Reattach wiring harness securely; check for moisture-resistant seal.
Test Operation: Reconnect battery, start engine, and verify that the fan engages automatically at set temperature (typically ~90–95°C).
