Radiator cover – genuine HOWO complete front grille and mask assembly kit for MAX 4X2
This radiator cover kit includes every panel, frame, bracket, hinge, and fastener needed to fully rebuild the front grille and mask assembly. No extra parts are required, making the radiator cover a complete, all‑in‑one solution for front‑end restoration.
All components of this radiator cover are manufactured from the same high‑quality materials as the original parts, with UV‑stabilised plastics and corrosion‑resistant coatings that ensure a long service life and a factory‑fresh appearance.
The radiator cover hinges and air springs are designed for smooth, effortless tilting, allowing easy access to the engine bay. The gas springs are calibrated to support the weight of the cover, making lifting and lowering controlled and safe.
Every bolt, nut, screw, clip, and washer needed to install the radiator cover is included. This eliminates the need to search for correct hardware and ensures that all fasteners are of the correct grade and finish for a durable, rattle‑free assembly.
The radiator cover is the first line of defence for the cooling system, directing airflow through the radiator while providing a sleek, aerodynamic front profile. The face shield and central grille frame form the main structure, with the air guide covers channelling air efficiently. The hinge brackets and front cover hinge plates attach the radiator cover to the cab frame,
allowing the entire assembly to be tilted forward for engine service. The air springs assist in lifting the heavy cover, reducing the effort required for maintenance.
The trim panels and garnish complete the interior and exterior appearance, ensuring a seamless transition between the cover and the cab. The blanking caps and fasteners secure all panels, preventing rattles and maintaining alignment. A properly installed radiator cover not only enhances the vehicle’s appearance but also protects the radiator and engine from debris, contributing to the overall reliability of the cooling system.
Begin by removing the old radiator cover and cleaning the mounting points on the cab and the existing brackets. Install the hinge brackets onto the cab frame using the provided hexagon head bolts, spring washers, and flat washers, torquing to specification. Attach the front cover hinge plates to the cab and connect the hinge pins,
securing them with the elastic snap rings. Mount the upper air spring brackets and attach the air springs. Assemble the central grille frame and face shield, then fit the air guide covers and trim panels.
Secure all components using the cross‑recessed tapping screws and the A‑type spring nuts. Install the blanking caps into any unused holes. Adjust the alignment of the cover to ensure even gaps and smooth operation of the tilting mechanism.
Test the air springs by lifting and lowering the radiator cover several times. Finally, torque all fasteners to the recommended values and check that the cover is secure and free from rattles. The radiator cover installation is now complete.
If the radiator cover does not close securely, check the right cover lock holders for alignment and ensure the air springs are correctly seated. A loose or rattling cover often indicates loose fasteners; retorque all bolts and screws. If the cover is difficult to lift, the air springs may have lost pressure; replace them with genuine components.
Misaligned panels can be adjusted by loosening the mounting screws and repositioning the trims. If the hinges are stiff, lubricate the hinge pins and bushings with a light grease. Missing blanking caps should be replaced to prevent moisture ingress. Always use genuine radiator cover components for repairs to maintain proper fit and function.
Inspect the radiator cover at every scheduled service (every 50,000 km). Check all fasteners for tightness and retorque if necessary. Lubricate the hinge pins and air spring connections with a silicone spray to ensure smooth operation. Clean the face shield and grille with a mild detergent to remove dirt and debris.
Inspect the air springs for signs of leakage or corrosion; replace them if the cover does not stay open. Check the trim panels for cracks or fading and replace any damaged parts. Keeping the radiator cover well‑maintained ensures that the cooling system receives adequate airflow and that the front of the vehicle retains its original appearance.
This radiator cover kit is specifically designed for the HOWO MAX 4X2 NX cab and is compatible with all production years from 2018 onward. It fits both MC11 and MC13 engine variants and is suitable for vehicles with standard air conditioning and cooling packages.
The kit is also compatible with SITRAK C7H and HOWO T7H models that share the same front mask architecture. It is not compatible with older A7 or WD615 models, which have different grille dimensions and hinge positions. Always verify your vehicle’s cab type before ordering the radiator cover.
Aftermarket radiator cover components often use inferior plastics that fade, warp, or crack under UV exposure, detracting from the vehicle’s appearance and allowing debris to enter the cooling system. Generic hinges and air springs may not support the weight of the cover correctly, leading to difficult operation or sudden closure.
Non‑genuine fasteners can rust or strip, causing panels to become loose and rattle. A damaged radiator cover can compromise airflow to the radiator, leading to engine overheating. Genuine HOWO radiator cover components are manufactured to SINOTRUK’s exacting standards,
using UV‑stabilised materials, precision‑engineered hinges, and high‑grade fasteners. The small additional cost of a genuine radiator cover is far outweighed by the protection it provides to the cooling system and the preservation of the vehicle’s resale value.
