The part is a complete cooling fan assembly for the HOWO MAX 4X2 tractor, integrating a high-performance fan clutch, a ring-type fan, and precision mounting hardware. This 202V06600-7060-2 kit ensures optimal engine cooling, reduced parasitic loss, and quiet operation. When you choose authentic Howo Parts, this 202V06600-7060-2 guarantees OE fitment and long-term reliability. Below are detailed descriptions of every component included with this 202V06600-7060-2 assembly.
The fan clutch is a thermostatically controlled viscous coupling that engages the fan only when engine cooling is required. This 202V06600-7060-2 component is filled with high-grade silicone fluid that shears under temperature control, providing infinitely variable fan speed. The clutch housing is made from cast aluminium with precision-machined bearing surfaces,
ensuring smooth operation and long service life. The part fan clutch is calibrated to engage at approximately 85°C, delivering maximum cooling when needed while reducing drag during cold starts and highway cruising, thereby improving fuel economy. A failing fan clutch can cause overheating or excessive noise; replacing it with a genuine 202V06600-7060-2 unit restores proper cooling system function.
The ring-type fan is a 750mm diameter, nine-blade fan with a reinforced ring structure that reduces flex and increases airflow efficiency. This 202V06600-7060-2 fan is moulded from glass-filled nylon, offering excellent strength-to-weight ratio and resistance to heat and fatigue.
The blades are aerodynamically curved to maximise air movement while minimising noise. The ring design also provides additional structural integrity, preventing blade flutter at high rotational speeds. This 202V06600-7060-2 fan is designed to bolt directly to the fan clutch using the supplied bolts, ensuring perfect balance and vibration-free operation. A damaged fan blade can cause imbalance and severe vibration; replacing the entire fan with a genuine 202V06600-7060-2 unit ensures safe and efficient cooling.
Six flange bolts (M8x16, grade 8.8) are supplied to secure the ring-type fan to the fan clutch. These 202V06600-7060-2 bolts feature an integral flange that distributes clamping load evenly,
eliminating the need for separate washers. The MAN183 quality mark indicates compliance with Sinotruk’s stringent manufacturing standards. The bolts are zinc-plated for corrosion resistance and include a thread locking patch that prevents loosening under vibration. Torque these 202V06600-7060-2 bolts to 20 Nm in a crossing pattern to ensure uniform clamping and prevent fan wobble. Using the correct hardware is essential for maintaining fan balance and preventing premature failure.
202V06600-7060-2 – genuine HOWO cooling fan and clutch kit for MAX 4X2
This 202V06600-7060-2 kit provides the fan clutch, fan, and all mounting bolts in one package. No need to source separate components; The part ensures perfect match and balanced assembly.
The fan clutch in The part uses silicone fluid to automatically adjust fan speed based on temperature. This 202V06600-7060-2 feature reduces fuel consumption and noise by disengaging the fan when cooling demand is low.
The 750mm ring-type fan in this 202V06600-7060-2 kit delivers high airflow with low noise. The ring design minimises blade deflection, ensuring consistent performance and extended service life of The part assembly.
The part comes with six grade 8.8 flange bolts with thread locking patches. These fasteners ensure secure attachment, preventing fan loosening or imbalance under the harshest operating conditions.
The part cooling fan system is driven by the engine serpentine belt. The fan clutch hub is attached to the water pump pulley, and the fan is bolted to the clutch. When the engine is cold, the clutch allows the fan to slip,
reducing parasitic drag. As coolant temperature rises, the thermostatic coil expands, opening a valve that allows silicone fluid to engage the clutch, driving the fan at high speed to pull air through the radiator. The ring-type fan is designed to maximise airflow while minimising turbulence. The correct engagement of The part system ensures that the engine operates within the optimal temperature range, preventing overheating and maintaining fuel efficiency.
Before installing The part, ensure the engine is cool and the battery is disconnected. Remove the old fan and clutch assembly. Clean the water pump pulley mounting surface. Apply a small amount of anti-seize compound to the new clutch threads. Mount the fan clutch to the pulley using the original retaining bolts (not supplied) and torque to specification.
Position the ring-type fan onto the clutch pilot, aligning the six bolt holes. Insert the M8x16 flange bolts and tighten them in a crossing pattern to 20 Nm. Check fan rotation for clearance and ensure it does not contact the radiator, shroud, or hoses. Reconnect the battery and start the engine. Verify that the fan engages as the engine warms up. The part installation is now complete.
If the engine overheats despite The part being installed, check that the fan clutch engages when the coolant reaches operating temperature. A failed clutch may not engage, causing insufficient airflow.
Listen for a roaring sound at high speed; if the fan runs constantly, the clutch may be seized, reducing fuel economy. Vibration or wobble indicates an incorrectly balanced fan or loose bolts. Inspect the fan blades for cracks or missing sections. If the fan does not engage at all, the thermostatic coil may be faulty. Always replace The part with a genuine unit if any of these symptoms occur. Ensure the drive belt is properly tensioned and not slipping.
The part cooling fan system requires minimal maintenance. Inspect the fan blades for damage and the clutch for oil leaks annually or every 50,000 km. Check the mounting bolts for tightness; retorque to 20 Nm if necessary.
The fan clutch is a sealed unit and does not require fluid replacement. If the vehicle operates in dusty environments, periodically clean the fan and radiator core with compressed air. Replace The part if the fan clutch becomes noisy or shows signs of leakage. Regular inspection of The part ensures consistent cooling performance and extends the life of the engine.
This 202V06600-7060-2 kit is specifically designed for the HOWO MAX 4X2 tractor equipped with MC11 and MC13 engines. It is compatible with all production years from 2018 onward. The fan clutch mounting pattern matches the standard water pump pulley.
The 750mm ring-type fan is sized for the MAX 4X2 radiator and shroud. This 202V06600-7060-2 is also suitable for SITRAK C7H and HOWO T7H models that share the same cooling system architecture. It is not compatible with older WD615 or A7 models, which use different fan diameters and clutch bolt patterns. Always verify your vehicle’s engine and cooling system before ordering The part.
Aftermarket fan clutches often use lower-quality silicone fluid that degrades quickly, leading to poor engagement and overheating. Generic fans may have incorrect blade angles or unbalanced mouldings,
causing vibration and noise. Non-genuine bolts may be made of softer steel, risking failure under thermal stress. A failed cooling fan system can cause engine overheating, leading to head gasket failure or cracked cylinder heads. Genuine HOWO 202V06600-7060-2 components are manufactured to Sinotruk’s exacting standards, using certified silicone fluid, precision-balanced fan blades, and high-grade fasteners. The small additional cost of a genuine 202V06600-7060-2 is negligible compared to the cost of a major engine repair.
