The engine cooling fan is a critical component that ensures your diesel engine maintains optimal operating temperatures, preventing overheating and ensuring reliable performance under the heaviest loads. The 1005514328 Fan from HOWO is engineered to deliver exceptional airflow, outstanding durability, and a precise factory fit, guaranteeing that your engine stays cool and efficient in the most demanding conditions. As a vital Howo/Sitrak truck parts component, this fan is manufactured from high‑grade composite material or steel, featuring precision‑balanced blades that provide maximum airflow with minimal noise and vibration. Whether you are replacing a worn fan or upgrading your cooling system, the 1005514328 guarantees a perfect factory fit, reliable cooling performance, and extended engine life – making it the trusted choice for professional workshops and fleet operators worldwide.
The engine cooling fan is responsible for drawing air through the radiator, dissipating the heat generated by the engine during operation. The 1005514328 is specifically designed to provide the high‑volume airflow required to cool large displacement diesel engines, even at idle or low vehicle speeds. A worn or damaged fan can lead to insufficient airflow, causing the engine to overheat, which can result in reduced power, increased fuel consumption, and catastrophic engine damage. HOWO has engineered this fan with precision‑molded blades that are aerodynamically optimized to produce maximum airflow while minimizing noise and parasitic drag. The fan’s robust construction and high‑quality materials resist cracking, warping, and fatigue, ensuring reliable performance over millions of operating cycles. With the 1005514328, you ensure that your engine remains cool, protecting your investment and ensuring reliable operation.

The 1005514328 fan is the product of advanced aerodynamic design and high‑quality manufacturing processes. The blades are carefully sculpted to optimize the angle of attack and surface area, delivering maximum airflow while minimizing turbulence and noise. The use of high‑strength composite materials in many variants provides excellent fatigue resistance and weight reduction, while steel versions offer exceptional durability for the most demanding applications. The fan is dynamically balanced to ensure smooth operation, reducing vibration that can lead to premature bearing wear in the fan clutch or water pump. The center hub is precisely machined to fit the fan clutch or direct‑drive mounting, ensuring perfect alignment and preventing wobble. Each fan is inspected for dimensional accuracy, balance, and blade integrity, guaranteeing that the 1005514328 meets HOWO’s stringent quality standards. This engineering excellence ensures that your engine cooling system operates at peak efficiency, keeping your engine cool and protected even under the most extreme conditions.
The 1005514328 fan is specifically designed for HOWO heavy‑duty trucks equipped with MC11 and MC13 engine families, including T7H, A7, and derivative models. It directly replaces the original fan, matching the mounting bolt pattern, diameter, and clutch interface, ensuring a straightforward installation without modifications. The fan is compatible with both viscous fan clutches and direct‑drive systems, and it works seamlessly with the factory radiator and shroud. This fan is also compatible with many Sinotruk and other commercial vehicles that share the same cooling system architecture. To confirm fitment, always cross‑reference the OEM number on your existing fan with 1005514328. If they match, this component will integrate seamlessly. Keeping this fan in your spare parts inventory ensures rapid cooling system repairs, minimising downtime and protecting your engine from overheating.

Replacing a worn, cracked, or inefficient fan with the 1005514328 immediately restores the cooling capacity of your engine’s cooling system. The optimized blade design delivers increased airflow, ensuring that the radiator dissipates heat effectively, even at low vehicle speeds or during idle conditions. This prevents engine overheating, which can lead to reduced power, increased fuel consumption, and costly engine damage. The dynamic balancing of the fan reduces vibration, extending the life of the fan clutch and water pump bearings. The durable construction ensures that the fan resists cracking and fatigue, providing long‑term reliability. For fleet operators, a reliable engine fan reduces the risk of cooling system failures, lowers maintenance costs, and helps maintain the performance and efficiency of your vehicles. By investing in the 1005514328, you ensure that your HOWO engine remains cool, protected, and ready for the road ahead.
Installing the 1005514328 fan is a straightforward procedure. Begin by safely supporting the vehicle and removing the fan shroud if necessary. Loosen the retaining bolts or nuts that secure the fan to the fan clutch or water pump hub. Carefully remove the old fan, taking care not to damage the radiator or other components. Clean the mounting surface and inspect the fan clutch or hub for any damage. Position the new fan onto the hub, ensuring that the mounting holes align correctly. Install the retaining bolts and torque them to the manufacturer’s specification (typically 20‑25 Nm). Reinstall the fan shroud and check for any clearance issues. Start the engine and listen for any unusual noises or vibrations. Periodically inspect the fan blades for cracks, chips, or signs of fatigue, and replace the fan if any damage is found. With proper installation, the 1005514328 will provide years of reliable cooling performance.
Pro Tip: When replacing the fan, it is recommended to also inspect the fan clutch for proper operation. A failing fan clutch can cause excessive noise or insufficient fan engagement, reducing cooling performance. The 1005514328 is designed to work with OEM fan clutches; using genuine components ensures optimal cooling system performance.
Genuine HOWO components are engineered to the highest standards, and the 1005514328 fan is no exception. Aftermarket fans often use inferior materials, less precise blade geometry, or poor balancing, leading to reduced airflow, increased noise, and premature failure. HOWO’s fan is manufactured using the same materials and processes as the original equipment, guaranteeing a perfect fit and reliable performance. By choosing the 1005514328, you benefit from HOWO’s rigorous testing, including aerodynamic performance, vibration, and durability tests.
