eliminating the need for separate washers. The MAN183 quality mark indicates compliance with Sinotruk’s stringent material and manufacturing standards. The bolts are zinc‑plated for corrosion resistance and include a pre‑applied thread locking patch that prevents loosening under vibration.
Torque these 202V06600-7060-3 bolts to 20 Nm in a crossing pattern to ensure uniform clamping and prevent fan imbalance. Using the correct fasteners is critical for maintaining the integrity of The part assembly and preventing failure due to bolt loosening or stripping.
202V06600-7060-3 – genuine HOWO electrically controlled silicone clutch and fan kit for MAX 4X2
The part clutch uses ECU‑controlled engagement, providing instant and precise fan speed adjustment. This 202V06600-7060-3 feature ensures that the engine always operates at the ideal temperature, improving fuel efficiency and reducing emissions.
The part clutch disengages the fan when cooling is not required, cutting parasitic drag significantly. This 202V06600-7060-3 innovation translates to up to 5% fuel savings in long‑haul applications.
The 750mm ring‑type fan in this 202V06600-7060-3 kit is engineered for high airflow and low noise. The ring design minimises blade flex, 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 a secure, balanced installation, preventing fan wobble and premature failure.
The part system is an intelligent cooling solution that integrates with the vehicle’s CAN bus. The ECU continuously monitors coolant temperature, ambient temperature, and engine load. When cooling is needed, the ECU sends a PWM signal to the clutch’s electromagnetic coil, which modulates the flow of silicone fluid,
engaging the fan at the required speed. The part clutch can vary fan speed from 0 to 100% in milliseconds, providing precise temperature control. This eliminates the thermal lag of traditional viscous clutches and reduces the risk of overheating during sudden load changes.
The ring‑type fan is designed to deliver high static pressure, ensuring adequate airflow even at low engine speeds. The combination of electronic control and aerodynamic fan design makes The part the most efficient cooling solution for the HOWO MAX 4X2, contributing to lower fuel consumption and reduced noise levels.
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 and the clutch mounting surface. Apply a small amount of anti‑seize compound to the clutch thread. Mount the electrically controlled silicone clutch to the water pump pulley using the original retaining bolts (torque to specification).
Position the ring‑type fan onto the clutch pilot, aligning the six bolt holes. Insert the supplied 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. Connect the electrical harness to the clutch connector, ensuring the latch clicks securely. Reconnect the battery and start the engine. Using a diagnostic tool, verify that the ECU recognises the clutch and that fan engagement occurs as coolant temperature rises. The part installation is now complete.
If The part fan does not engage when the engine is hot, check the electrical connector for corrosion or loose pins. Verify that the ECU is sending a PWM signal using a multimeter. A fan that runs constantly may indicate a short circuit or a faulty clutch;
replace The part unit. Vibration or wobble suggests an imbalance; check that all bolts are tightened evenly and that the fan is not damaged. If the fan makes excessive noise, inspect the bearing and the fan blades for cracks. Always replace The part with a genuine unit if any of these symptoms occur. Ensure the drive belt is properly tensioned and the water pump pulley is in good condition.
The part cooling fan system requires periodic inspection. Annually or every 50,000 km, check the fan blades for damage, the clutch for oil leaks, and the electrical connector for corrosion. Verify that the mounting bolts remain tight; retorque to 20 Nm if necessary.
The clutch is a sealed unit and does not require fluid replacement. If the vehicle operates in dusty environments, clean the fan and radiator core with compressed air. Replace The part if the clutch becomes noisy, fails to engage, or shows signs of electrical malfunction. Regular inspection of The part ensures consistent cooling performance, protects the engine, and maintains fuel efficiency.
