Engineered for extreme durability, the VG1500060402 F640 silicone oil fan represents the pinnacle of thermal management for heavy-duty trucks. When you choose genuine Howo/Sitrak truck parts, you invest in precision cooling that extends engine life and reduces fuel waste. This fan isn’t just a component – it’s a performance partner that adapts to every load, every grade, and every climate.
The F640 silicone oil fan (OEM VG1500060402) is not an ordinary cooling solution. It uses high-viscosity silicone fluid that responds to temperature changes in real time. When the engine runs hot, the fan engages firmly; when cruising cold, it disengages to save power. This intelligence translates to 5–8% fuel savings in fleet tests, and a noticeable reduction in noise at highway speeds.
Every unit of VG1500060402 is factory-calibrated for HOWO and SITRAK engines, ensuring a plug-and-play fit without modifications. The housing is corrosion-resistant, and the silicone oil retains its viscosity over thousands of thermal cycles.
Unlike cheap aftermarket fans, the F640 silicone oil fan with part number VG1500060402 features a bimetallic coil that controls the valve opening. This mechanical intelligence ensures that the fan only draws power when needed. During cold starts, the fan remains disengaged, allowing the engine to warm up faster – reducing wear and emissions.
The blade pitch is optimized for high static pressure, making it ideal for stop-and-go traffic and mountainous routes. The silicone oil filling is precisely metered; too little and the fan slips, too much and it drags. Our VG1500060402 units are filled within ±2% tolerance, guaranteeing consistent performance across all operating temperatures.
In real-world operation, the F640 silicone oil fan (VG1500060402) has been validated on over 500,000 km of mixed terrain. Fleet managers report a noticeable drop in coolant temperature spikes during long climbs, and drivers appreciate the consistent cabin A/C performance due to stable engine temperatures. The fan’s silicone oil maintains its shear stability, so you won’t experience the “drooping” effect seen in lower-quality units after 100,000 km.
We understand that downtime is costly. That’s why every VG1500060402 unit is packed with care, ensuring that you receive a component that mounts effortlessly and performs immediately. The fan hub is pre-filled with high-grade silicone oil, and the thermal spring is calibrated to OEM specifications. No additional setup or calibration is required – just bolt it on and drive with confidence.
Whether you operate in the scorching deserts of the Middle East, the freezing Nordic winters, or the humid tropics, the F640 silicone oil fan adapts. Its robust construction resists corrosion from road salt and moisture, and the bearing is sealed for life, eliminating the need for maintenance. This reliability makes it the preferred choice for global fleets that demand excellence.
The VG1500060402 F640 silicone oil fan is the definitive upgrade for HOWO and SITRAK trucks – engineered to deliver relentless cooling, fuel economy, and silence. Choose the part that professionals trust.
