This cooling unit features an electronic control module that directly reads ECU signals for precise speed regulation. It engages only when needed, reducing parasitic power loss during cold starts and highway cruising.
Unlike traditional units that run continuously, this electrically controlled silicone oil device activates only at optimal temperatures, reducing engine accessory load and significantly improving fuel economy.
This kit includes not only the main cooling component but also the bracket, clutch bracket, all mounting bolts, and wiring strapping tapes. Everything needed for a complete replacement is included.
The device operates reliably from -40°C to 180°C. Aerospace‑grade silicon fluid maintains consistent viscosity, while the triple‑sealed electromagnetic clutch resists moisture, dust, and road contaminants.
The unit is driven by the engine crankshaft via a serpentine belt. A silicon fluid coupling connects the hub to the drive pulley. An electronic control unit monitors coolant temperature, ambient air temperature, and engine load. When cooling is not required, the device idles, consuming minimal power. When engine temperature rises above a preset threshold, the ECU energizes an electromagnetic clutch, allowing silicon fluid to transmit torque to the blades.
The device then spins at maximum speed, drawing air through the radiator. The smart control module continuously adjusts speed based on real‑time conditions, providing precise cooling without unnecessary power consumption. MC13 engines benefit from reduced noise and vibration, contributing to a quieter cab environment.
Before installation, disconnect the battery ground cable. Remove the old cooling unit and brackets. Clean the engine block mounting surfaces. Install the main bracket onto the engine block using the four M10 shoulder bolts (torque to 50 Nm). Attach the clutch bracket using the four M8x25 bolts (torque to 25 Nm). Mount the electrically controlled silicone oil device onto the clutch bracket. Secure the unit with the remaining M8 bolts.
Connect the electrical harness to the engine wiring loom using the sealed connectors. Route the harness away from hot or moving parts and secure it with the fixed strapping tape and the single‑way wiring harness tape. Reconnect the battery and start the engine. Allow the engine to reach operating temperature and verify that the device engages when coolant temperature rises above the threshold. No further programming is required.
This cooling kit is specifically designed for the MC13 engine used in the HOWO MAX 4X2 tractor. It fits all production years from 2018 onward. The main bracket is compatible with the standard belt drive system. The electrically controlled device integrates seamlessly with the existing OEM wiring harness and mounting points. Comprehensive fitting kits include all necessary hardware for professional installation without vehicle modifications. The unit is also compatible with MC11 engines, but always verify your engine serial number before ordering.
Inspect the cooling device periodically for cracks or damage to the composite blades. Check the electrical connector for corrosion or loose pins. The clutch requires no routine lubrication as it is sealed for life. Listen for unusual noise during engagement; a grinding sound may indicate bearing wear, requiring replacement. The mounting bolts should be checked for tightness after the first 1,000 km of operation. The strapping tapes should be inspected for brittleness and replaced if cracked. With proper maintenance, this assembly will provide reliable service for over 15,000 hours.
If the engine overheats, first check that the cooling device engages when coolant temperature rises. A non‑engaging unit may indicate a faulty clutch or broken electrical connection. If it runs continuously at high speed, the temperature sensor or ECU may be faulty. A grinding noise suggests bearing wear in the clutch or bracket. If the blades are cracked or missing, replace the assembly immediately. Always use genuine HOWO parts for any repairs.
Aftermarket units often use lower grade composite materials that fatigue and crack. Generic clutches may not have precise electronic control logic, leading to poor cooling or excessive power consumption. The mounting brackets in copy kits may be made from inferior aluminum that cracks under vibration. Genuine HOWO components are manufactured to the exact specifications of the original MC13 engine, using aerospace‑grade silicon fluid, precision‑machined aluminum housings, and heavy‑duty bearings rated for over 15,000 hours. The small additional cost is far outweighed by the fuel savings and engine protection they provide.
