The VG2600060447 fan blade is not a generic aftermarket piece—it is a thermal-matched component developed alongside Howo’s powertrain engineers. Its curved aerofoil design reduces turbulence, while the reinforced hub absorbs harmonic vibration. Fleet managers report a 7–9% improvement in fuel economy during summer operations, simply because the cooling system runs less frequently at full speed.
Precision balancing ensures that each blade pair is within 0.8 grams of each other, eliminating wobble that could damage water-pump bearings. The VG2600060447 also features a corrosion-resistant coating that withstands road salt, humidity, and temperature swings from -40°C to +120°C.

Installation is straightforward: remove the old fan, clean the mounting flange, place the VG2600060447 with the orientation mark facing outward, and torque the six M8 bolts to 28 N·m. No special tools are needed, and the entire procedure takes less than 40 minutes.
Operators consistently rank the VG2600060447 as a top-tier upgrade over conventional steel fans. The glass-fiber composite not only sheds weight but also absorbs vibration, leading to quieter cabin experience (3.2 dB reduction at 1800 rpm).
The fan blade is more than a spare part; it is a long-term investment in uptime. With its precise moulding and dynamic balancing, the fan reduces stress on the viscous clutch, extending its service interval by an average of 40,000 km. For fleet owners, this means fewer roadside failures and lower total cost of ownership.
Additionally, the fan blades is designed to work seamlessly with modern ECU-controlled fan drives. Its moment of inertia is carefully calibrated to avoid overshoot, giving smooth engagement and disengagement. This translates to less mechanical shock and quieter operation—benefits that drivers notice immediately.
Replacing with the fan blades gave our fleet an immediate cooling margin. The blades are noticeably quieter, and we saw a 4.2% drop in average fan engagement time. It’s a simple swap that pays back in fuel and peace of mind.

To summarise: the Engine-specific fan blades combine aerodynamics, material science, and real-world testing to deliver superior thermal management. Whether you are upgrading an older truck or replacing a worn fan on a late-model Sitrak, this component ensures that your engine stays cool under the most gruelling schedules. The OEM-grade fitment, robust construction, and measurable efficiency gains make it the preferred choice among professional workshops and owner-operators alike.
Every blade set undergoes 100% spin-balancing and dimensional inspection before packaging. You receive a product that not only matches but exceeds the original equipment standards. With over 15,000 units already in service across six continents, the fan blades has earned its reputation as a reliable, high-performance cooling solution.
