The VG2600020226 is an 8-rib Poly-V (PK) serpentine belt designed specifically for the water pump drive in SINOTRUK Howo engine configurations. Its primary function is to transfer rotational power from the crankshaft pulley to the water pump pulley, ensuring consistent coolant circulation through the engine block, cylinder head, and radiator. This OEM belt is constructed with a focus on high tensile strength, flexibility, and resistance to the harsh under-hood environment of heat, moisture, and dynamic loads.
Manufactured to precise OEM specifications, the VG2600020226 belt features a multi-ribbed design that provides a large contact surface with the pulley grooves. This design maximizes grip and power transmission efficiency while allowing the belt to bend smoothly around smaller diameter pulleys with minimal energy loss. The belt’s internal reinforcement consists of high-modulus polyester or aramid cords that provide exceptional resistance to stretching, ensuring that the water pump maintains its designed speed ratio relative to engine RPM over the belt’s entire service life.
The exterior of the VG2600020226 belt is made from a specially formulated ethylene propylene diene monomer (EPDM) rubber compound. EPDM is renowned for its outstanding resistance to high temperatures, ozone cracking, and weathering, making it ideally suited for the constant heat cycles and exposure in a truck engine bay. This material maintains its elasticity and structural integrity far longer than conventional rubber compounds, directly contributing to the belt’s extended service interval and reliability.

The VG2600020226 belt is engineered as a direct replacement for the original water pump drive belt on specific SINOTRUK Howo truck models. Its compatibility is verified against factory specifications, ensuring the 8-rib profile and 1080mm length perfectly match the vehicle’s pulley system. This belt is typically part of a dedicated drive circuit or a shared accessory drive that may include other components, but its critical function is to ensure the water pump rotates at the correct speed proportional to engine RPM.
A dedicated water pump drive belt, like the VG2600020226, underscores the importance of reliable cooling system operation. By ensuring the water pump is driven independently or as a prioritized component, the system design guarantees coolant circulation even if other accessory belts fail. The precise length is calculated to work with the specific mounting points of the water pump, idler pulleys, and the crankshaft pulley, providing the correct wrap angle and tension for optimal power transmission.
For maintenance efficiency, stocking the genuine VG2600020226 part ensures the correct component is available for scheduled service. This prevents the installation of incorrect aftermarket belts that may have a different number of ribs or a slightly different length, either of which can lead to improper pulley alignment, slippage, or accelerated wear on the water pump bearing.
The performance and longevity of the VG2600020226 belt are rooted in advanced material science and precision manufacturing. The core tensile member consists of multiple cords made from high-modulus polyester or, in premium versions, aramid fibers. These cords are aligned longitudinally and are responsible for carrying the tensile load, providing exceptional resistance to elongation—a critical factor in maintaining consistent belt tension and water pump speed over thousands of operating hours.
The EPDM rubber compound that fully encapsulates the cord body is selected for its exceptional environmental resistance. Unlike traditional chloroprene, EPDM has a saturated polymer backbone, making it highly resistant to degradation from heat, ozone, oxygen, and steam—all common in the engine compartment. This results in a belt that remains flexible and resistant to surface cracking (checking) over a much longer period, even under continuous exposure to temperatures that can exceed 120°C (248°F).
The 8-rib PK profile is precision-molded to ensure each rib is uniform in size and shape. This consistency ensures even distribution of load across all ribs and provides smooth, quiet operation as the belt engages with the pulley grooves. The multi-rib design also allows for a more compact drive layout and higher power transmission capacity compared to classical V-belts, which is essential for modern high-performance diesel engines.

The VG2600020226 serpentine belt plays a non-negotiable role in the engine’s thermal management system. Its sole purpose is to ensure the engine-driven water pump operates continuously whenever the engine is running. The water pump is responsible for circulating coolant throughout the engine block, cylinder head, heater core, and radiator. This circulation is what transfers combustion heat away from critical engine components, preventing overheating, thermal distortion, and seizure.
A failure of the VG2600020226 belt results in the immediate cessation of coolant flow. Within minutes, the engine temperature will rise dangerously, leading to potential catastrophic damage such as warped cylinder heads, blown head gaskets, piston scuffing, and complete engine failure. Therefore, this belt is not merely an accessory drive component; it is a vital safety element for the engine itself. Its reliability is directly tied to the protection of one of the truck’s most valuable assets—its powertrain.
Beyond preventing overheating, a properly functioning water pump driven by the VG2600020226 belt also ensures efficient heater operation for cabin warmth in cold climates and helps maintain optimal engine operating temperature for fuel efficiency and reduced emissions.
Installation of the VG2600020226 belt should be performed by a qualified technician familiar with the engine’s accessory drive layout. The process typically involves using a tool to relieve tension on the automatic spring-loaded tensioner pulley, carefully routing the new belt according to the diagram (often found on the vehicle’s fan shroud or radiator support), and then releasing the tensioner to apply the correct preload. It is crucial to ensure the belt is fully seated in all pulley grooves across all ribs.
While automatic tensioners maintain optimal tension, a visual check of the tensioner’s indicator mark (if equipped) should be performed to confirm it is within the acceptable range. Incorrect routing or a belt not fully seated can cause immediate failure or severe damage to the belt and pulleys. After installation, run the engine and observe the belt for proper tracking without any signs of wandering or rib separation.
Preventive maintenance involves regular visual inspections during service intervals. Check the VG2600020226 belt for signs of wear such as cracks in the valleys between ribs, fraying or peeling of the rib edges, glazing (a shiny, hardened surface), or any signs of contamination from oil or coolant. The belt should be replaced proactively at the manufacturer’s recommended interval (often between 80,000 to 150,000 km) or at the first sign of significant deterioration. Concurrently, inspect the condition of all pulleys and the automatic tensioner for smooth rotation and wear.
Choosing the genuine VG2600020226 belt over aftermarket alternatives provides significant advantages in reliability, fit, and performance. Aftermarket belts may appear similar but often use different rubber compounds (such as cheaper chloroprene) and cord materials that do not meet the original durability specifications. The rib profile might also have slight variations in angle or depth, affecting grip and potentially causing noise or premature wear.
The OEM VG2600020226 belt is a system-engineered component. Its length, rib profile, and material properties are designed to work in perfect harmony with the specific pulley diameters, accessory loads, and tensioner characteristics of the SINOTRUK Howo engine. This ensures predictable performance, optimal accessory speed, and maximum service life. While an aftermarket belt might have a lower initial cost, the risk of premature failure leading to costly engine damage makes the genuine part a far more economical and safe choice in the long term.
For fleet operations, the predictable service life and known quality of an OEM belt like the VG2600020226 allow for accurate maintenance scheduling, reducing the likelihood of unexpected and expensive roadside breakdowns.
