100% Genuine Howo Water Pump

100% Genuine Howo Water Pump guarantees efficient engine heat dissipation, effectively avoiding engine overheating for heavy-duty HOWO trucks under mining and long-haul working conditions.

About Howo Water Pump

As a professional and reliable supplier of genuine Sinotruk heavy truck spare parts, we provide 100% genuine and high-performance Howo Water Pump for all series of HOWO heavy-duty trucks.
The Howo Water Pump serves as the core power component of the engine cooling system, driving coolant circulation between the engine block and radiator.
It efficiently dissipates excess heat produced during engine operation, avoiding overheating, coolant boiling and power loss, and maintains stable engine temperature under heavy-load, long-distance and high-temperature conditions.
Our Howo Water Pumps are manufactured with original casting technology, high-precision bearings and imported mechanical water seals, delivering zero leakage, high circulation efficiency and long service life.
We offer standard water pumps applicable to WD615, WP10, WP12 and D12 engines, perfectly matching Howo 371, 380, 420 and 430 HP trucks.

How Does The Howo Water Pump Work?

Initial Drive Mechanism

The Howo water pump adopts belt drive to transmit engine power. The engine crankshaft drives the V-belt or multi-wedge belt, and power is transferred to the water pump pulley to drive the whole pump assembly.

Impeller Operation

Driven by the pulley, the impeller fixed on the rotating shaft spins rapidly inside the sealed pump housing. Manufactured from high-strength cast iron, the impeller is equipped with curved blades to push coolant continuously.

Centrifugal Force Generation

High-speed rotation of the impeller produces centrifugal force. Coolant is sucked into the pump through the inlet and thrown outward by the impeller blades.

Coolant Circulation Cycle

The pressurized coolant flows out from the pump outlet and circulates inside engine water channels to absorb heat from cylinders and cylinder heads.

The hot coolant then flows to the radiator for heat exchange and cooling. After temperature reduction, the coolant returns to the water pump for repeated circulation.

For vehicles with heating systems, partial coolant will flow through the heater core to supply warm air for the cab.

Core Functions of Howo Water Pump

The genuine Howo Water Pump undertakes the most critical heat dissipation circulation task of the truck engine, directly determining engine stability and service life:

Continuous Coolant Circulation: Driven by engine belt, the high-speed rotating impeller circulates coolant between engine water jacket and radiator to realize continuous heat exchange.
Constant Engine Temperature Control: Maintain the engine working temperature within the standard safe range, avoid high-temperature cylinder deformation, oil deterioration and power drop.
Adapt to Harsh Working Conditions: Stable large-flow heat dissipation ensures normal engine operation even under continuous climbing, full-load driving and high-temperature environment.

Product Quality Advantages

All our 100% genuine Howo Water Pump strictly comply with Sinotruk OEM manufacturing standards, with obvious advantages in material, craftsmanship and performance compared with ordinary aftermarket pumps:

Integrated Casting Pump Body

Adopting high-strength cast iron integrated molding, the pump body is not easy to crack or deform under high temperature and high pressure, with strong shock resistance.

Imported Mechanical Water Seal

Equipped with high-temperature resistant and wear-resistant water seal components, effectively solving common water leakage problems of ordinary pumps and achieving long-term zero-leakage operation.

High-Precision Bearing & Impeller

Strictly polished impeller ensures large water flow and fast heat dissipation; high-precision bearings reduce operating resistance with low noise and no jamming.

100% Plug-and-Play Installation

Standard mounting holes and interface size fully match original trucks, no modification required during replacement, saving maintenance time and cost.

Compatible Truck Models & Application Scenarios

The genuine Howo Water Pump is a dedicated cooling system component for full-series Sinotruk HOWO heavy trucks, widely used in various engineering and logistics transportation fields:

HOWO 371/380/420/430HP 6×4 & 8×4 mining dump trucks
HOWO 4×2/6×4 long-distance logistics tractor trucks
HOWO concrete mixer trucks, fuel tank trucks and special engineering vehicles
Fleet regular maintenance, engine overhaul and old pump replacement renovation

Packaging of Howo Water Pump

Customized Layered Packaging: All genuine Howo Water Pumps adopt professional multi-layer export packaging, customized according to the precision structure and metal characteristics of
Full Product Protection: Finished water pump assemblies are equipped with shock-absorbing, rust-proof and moisture-proof packaging layers, effectively preventing surface wear, component loosening and metal corrosion during transportation.
Safe Bulk Packaging: Large-spec and bulk water pumps are firmly fixed on export wooden pallets or packed in fumigated wooden cases, resisting extrusion and vibration during long-distance sea freight to ensure complete product condition.
Independent Accessories Packaging: Supporting parts such as gaskets, water seals and fasteners are individually packaged with moisture-proof and dust-proof bags and stored in standard export cartons to avoid loss and damage.
Standard Shipping Marking: Each package is clearly labeled with OE part numbers, applicable engine models, specifications and quantities, facilitating customs clearance, cargo inspection and inventory management for global buyers.
