The 612600080914 Ventilateur is a mechanical engine cooling fan, typically driven by the engine’s crankshaft via a viscous clutch or a belt-driven hub. Its primary function is to draw a massive volume of ambient air through the radiator core when the vehicle is moving slowly or under high load, such as during idling, climbing steep grades, or operating in high ambient temperatures. This airflow is essential for transferring heat away from the engine coolant circulating in the radiator, thereby regulating the engine’s operating temperature within its optimal range.
Without a properly functioning fan like the 612600080914, the cooling system’s efficiency plummets at low speeds. This can lead to rapid engine overheating, which causes a cascade of problems: reduced engine power (derating), increased emissions, potential head gasket failure, warped cylinder heads, and in extreme cases, catastrophic engine seizure. The fan identified by part number 612600080914 is engineered to deliver the specific airflow and static pressure required by the FOTON truck’s cooling system package, ensuring balanced thermal management.
Therefore, the integrity of the 612600080914 is not merely about comfort; it is a fundamental safeguard for the engine’s health and operational capability. A cracked, unbalanced, or slipping fan can lead to insufficient cooling, excessive noise, and even damage to the radiator from vibration. Regular inspection and timely replacement with the genuine 612600080914 part are key preventive maintenance practices.
Optimized Aerodynamic Blade Design: The blades of the 612600080914 are precisely shaped and pitched to move the maximum volume of air with minimal power draw from the engine. This efficient design reduces parasitic load, contributing to better fuel economy while providing robust cooling capacity when needed.
Precision Balanced for Smooth Operation: The genuine 612600080914 undergoes dynamic balancing during manufacturing. This minimizes vibration at high rotational speeds, which protects the water pump bearings, fan clutch, and radiator from premature wear and failure, leading to a quieter and more reliable engine bay.
Durable, Engineered Material: Typically constructed from high-grade reinforced polymer (glass-filled PA66) or stamped steel, the 612600080914 is built to withstand extreme temperature fluctuations, constant stress cycles, and exposure to chemicals like coolant and road salts without cracking, warping, or corroding.
Direct OEM Fit and Compatibility: As a genuine part numbered 612600080914, it is a direct bolt-on replacement for the original fan. It matches the exact mounting bolt pattern, hub interface, and diameter, ensuring proper clearance within the shroud and safe, hassle-free installation without modification.
Beyond these primary features, the 612600080914 is designed to work in perfect harmony with the vehicle’s specific viscous fan clutch or drive hub. The correct blade count and diameter ensure the fan does not overload the clutch mechanism. For fleet managers, using the genuine 612600080914 ensures predictable cooling performance, eliminates compatibility issues, and protects the significant investment in the engine by maintaining its ideal operating temperature.

Note: The exact diameter and blade count for part number 612600080914 can vary based on the specific engine and radiator configuration. Always confirm the physical specifications against your vehicle’s original fan or consult the official FOTON parts catalog using your engine number or VIN.
The 612600080914 Engine Cooling Fan is designed for specific FOTON truck models equipped with medium to heavy-duty diesel engines, such as those in the Aumark series (particularly heavier variants), certain Forland models, and other trucks featuring Cummins ISF series or similar engines. It is a critical component of the vehicle’s front-end cooling module, working in conjunction with the radiator, viscous fan clutch, and fan shroud.
This component is indispensable in operational scenarios that generate high engine heat with low natural airflow. This includes prolonged idling (e.g., during loading/unloading or while operating a PTO), slow-speed heavy hauling on construction sites, driving in mountainous terrain, and operating in hot climates. A failure of the 612600080914 fan in these conditions can lead to immediate engine overheating warnings and forced downtime.
Compatibility is determined by several factors: the engine model, the type of viscous fan clutch used, the diameter and depth of the fan shroud, and the available clearance in the engine bay. The genuine 612600080914 is engineered to match all these parameters. Using an incorrect fan can result in it hitting the shroud or radiator, providing insufficient airflow, overloading the fan clutch, or creating excessive noise. Therefore, verifying the part number 612600080914 against the vehicle’s specifications is a crucial step.
Installation Overview: Replacing the 612600080914 requires careful attention. First, ensure the engine is cool and disconnect the battery. Safely drain a portion of the coolant and remove components obstructing access, such as the fan shroud. The fan clutch and fan assembly (612600080914) are usually removed as a unit. Support the fan clutch while loosening the mounting bolts (often a reverse thread on the water pump pulley). Once removed, separate the old fan from the clutch. Mount the new 612600080914 onto the clutch, ensuring all bolts are tightened to the specified torque in a crisscross pattern. Reinstall the assembly, reconnect all components, refill coolant, and test for proper operation and clearance.
Critical Installation Tips: Always use a thread-locking compound on the fan-to-clutch mounting bolts as specified by the manufacturer. Ensure the fan is seated evenly on the clutch hub. When reinstalling, do not use the fan blades as a lever to tighten the clutch mounting nut; this can damage the new 612600080914. Always use the proper tools. Double-check that there is equal clearance (usually about 10-15mm) between all fan blade tips and the surrounding shroud after installation. Start the engine and listen for any rubbing or imbalance noises at various RPMs.
Maintenance and Inspection Schedule: The 612600080914 itself requires no active maintenance, but the entire cooling system should be inspected regularly. Visually inspect the fan for cracks, chips, or significant dirt/oil buildup that can imbalance it. Check for loose mounting bolts. Listen for abnormal roaring or grinding noises that may indicate a failing fan clutch, which puts extra stress on the fan. During coolant system service, ensure the fan shroud is intact and correctly positioned. The most common cause of fan failure is a seized or failing viscous clutch, so its condition should be assessed whenever the fan, part number 612600080914, is serviced.
Selecting the authentic 612600080914 Engine Cooling Fan guarantees a component that meets FOTON’s strict specifications for material strength, aerodynamic performance, and dynamic balance. Aftermarket fans may use inferior plastics that become brittle with heat cycles, have imprecise blade angles that reduce airflow, or are poorly balanced. An unbalanced fan, even if slightly off, creates damaging vibrations that can quickly destroy water pump seals and bearings and lead to radiator tank failure.
For fleet operators and workshops, using the documented part number 612600080914 ensures perfect fitment and predictable cooling performance. The genuine fan is designed to work within the specific acoustic and power draw limits of the FOTON vehicle. It also ensures the correct weight and inertia for the viscous clutch to operate efficiently, preventing clutch slippage or engagement issues.
Economically, the genuine 612600080914, while sometimes a higher initial investment, prevents far more costly secondary damage. The cost of a replacement fan is minimal compared to the expense of repairing a damaged radiator, water pump, or even an overheated engine. Its reliability ensures vehicle uptime, prevents roadside breakdowns due to overheating, and protects the major investment in the truck’s powertrain.
Each 612600080914 Ventilateur (Engine Cooling Fan) is manufactured to FOTON’s exacting quality standards, undergoing checks for dimensional accuracy, material integrity, and dynamic balance before dispatch. Supplied as a standalone fan assembly, this component is essential for maintaining the thermal management system and long-term health of your FOTON truck’s engine.
Important Safety Notice: This information is intended for professional technicians. Working on engine cooling systems involves rotating components and hot fluids.
