The Cylinder head cover component plays a vital role in sealing the top of the engine and housing critical valve train parts. For your HOWO MAX 4X2, this Cylinder head cover component ensures proper crankcase ventilation and oil control. Genuine howo Parts deliver superior fit and durability. This complete set includes the electronic silicone oil clutch, ring fan, and mounting bolts. Every Cylinder head cover component is precision cast and pressure tested to prevent leaks. Below we detail each essential element of this assembly.
The Cylinder head cover component works together with the cooling fan drive system to maintain optimal operating temperature. A reliable Cylinder head cover component reduces oil mist escape and prolongs valve train life. Explore the components below.
The electronically controlled silicone oil clutch ER175 (1084) is a viscous fan drive that engages the fan based on engine temperature. This clutch receives PWM signals from the ECU to modulate fan speed precisely. When the Cylinder head cover component area detects high heat, the clutch locks up to increase airflow. The silicone oil inside provides smooth torque transfer without mechanical wear. This ER175 model is calibrated for HOWO MAX 4X2 heavy duty cycles.
The clutch housing is made of aluminum alloy with thermal conductive coating. Its integrated speed sensor allows closed-loop control, reducing parasitic drag by up to 40%. For the Cylinder head cover component, proper fan clutch operation prevents localized hot spots and prolongs gasket life. This unit is maintenance-free and filled with high-viscosity silicone fluid for life.
Installation requires no special tools; the clutch bolts directly to the water pump hub. Always replace the clutch if you notice constant fan engagement or overheating. The ER175 is a direct OE replacement for original Cylinder head cover component cooling systems.
The ring-type fan with 750mm diameter moves high volumes of air across the radiator and engine. Nine blades are arranged in a circular ring that reduces turbulence and noise. When the Cylinder head cover component requires additional cooling, this fan generates airflow up to 12,000 m³/h at maximum clutch speed. The ring design also improves structural rigidity and reduces blade flex at high RPM.
The fan is manufactured from glass-fiber reinforced polyamide, which resists cracking from road debris and thermal cycling. It is balanced dynamically to minimize vibration transmitted to the Cylinder head cover component and other engine parts. The ⌀750 size matches the HOWO MAX 4X2 fan shroud perfectly. A damaged fan can cause severe overheating; inspect it regularly for cracks or missing blades.
When replacing the fan, always use the correct bolt torque to prevent hub distortion. The ring-type fan is lightweight yet durable, making it an essential partner to the Cylinder head cover component in extreme ambient temperatures.
Six flange bolts of size M8x16, property class 8.8, secure the ring-type fan to the silicone oil clutch hub. The integrated flange eliminates the need for separate washers and distributes clamping load evenly. These bolts are coated to MAN183 standard, providing 240h salt spray resistance. For the Cylinder head cover component cooling assembly, correct bolt torque of 25 Nm prevents fan wobble that could damage the water pump bearing.
The hexagonal head allows easy access with a standard socket. Always replace these bolts when installing a new clutch or fan, as thread deformation can occur after removal. The bolts are supplied pre-oiled for consistent friction coefficient. Using genuine hardware ensures that the Cylinder head cover component cooling system remains vibration-free and reliable for millions of kilometers.
These bolts are also used in other engine dressings, but for the fan attachment they are critical. Do not substitute with generic bolts of lower grade. The MAN183 B1 marking guarantees traceability and factory quality.

The clutch’s fail‑safe mode defaults to 80% engagement if temperature sensor fails, protecting the Cylinder head cover component from overheating. Diagnostic trouble codes can be read via standard OBD.
The ⌀750 ring-type fan shifts 30% more air than conventional fans at the same speed while producing lower noise. Its nylon composite withstands 120°C continuous operation.
Dynamic balancing to ISO 1940 grade G6.3 eliminates vibration that could loosen bolts or crack the Cylinder head cover component. The fan ring also prevents blade tip damage.
Our Cylinder head cover component comes as a ready‑to‑install set including all six flange bolts, the fan, and clutch pre‑assembled. Each component carries ISO/TS 16949 certification.
We provide a 12‑month unlimited‑mileage warranty. Trusted by fleets across Africa and the Middle East, this Cylinder head cover component ensures uptime and cooling efficiency.
The Cylinder head cover component on the HOWO MAX 4X2 is more than just a cover; it houses the rocker arms, injector harnesses, and the crankcase ventilation system. A warped Cylinder head cover component can cause oil leaks onto the exhaust manifold, creating smoke and fire risk. Replacing it with a genuine part restores proper sealing and maintains engine cleanliness.
When you install this Cylinder head cover component kit, you also upgrade the fan drive system. The electronically controlled silicone oil clutch constantly adjusts fan speed according to coolant temperature, intake air temperature, and air conditioner condenser pressure. This intelligent control reduces parasitic load on the engine, improving fuel economy by 1.5% to 2% in highway driving. For a heavy truck covering 150,000 km per year, that translates to significant savings.
The ring‑type fan (⌀750) is specifically designed for the densely packed engine bay of the MAX 4X2. Its swept blades are angled to maximise air throw into the radiator core while minimising recirculation. The fan ring also acts as a containment device in case of blade failure, preventing debris from damaging the Cylinder head cover component or other nearby sensors. All six hexagon flange bolts are included with pre‑applied thread locker to ensure they never back out under high vibration.
Maintenance of the Cylinder head cover component is often overlooked. Every 100,000 km, inspect the cover for oil sweating around the edges. The integrated rubber gasket may harden over time; replacing the entire Cylinder head cover component ensures a fresh gasket and clean oil separator. The silicone oil clutch should be checked for oil seepage; a leaky clutch cannot lock up fully, leading to overheating. The ⌀750 fan should be rotated by hand – any roughness indicates a failing bearing in the clutch or water pump.
Installation of the Cylinder head cover component begins with removing the old cover and cleaning the cylinder head rail surface. Use only plastic scrapers to avoid gouging aluminum. Place the new cover with its pre‑positioned gasket, then torque the 10 cover bolts in sequence from the center outward to 12 Nm. For the fan drive, mount the ER175 clutch to the water pump pulley with four M8 bolts, then attach the ring fan using the six M8x16 flange bolts. Tighten them crosswise to 25 Nm. Reconnect the clutch PWM connector and verify that the fan spins freely before starting the engine.
After replacing the Cylinder head cover component, run the engine at idle for 15 minutes then re‑check torque. The gasket will compress slightly; a second retorque is recommended. For the fan system, use a diagnostic tool to command the clutch on and off; you should hear the fan engage audibly. The coolant temperature should stabilise between 85°C and 95°C under load. If the temperature exceeds 100°C, re‑evaluate the Cylinder head cover component cooling circuit and ensure no air pockets exist.
