The WG9719530017 Expansion Tank Hose is a critical cooling system component engineered to ensure a secure and uninterrupted flow of coolant between the radiator and the expansion tank in SINOTRUK Howo heavy-duty trucks. As a trusted supplier of genuine Sinotruk howo parts, we offer this hose as a direct OEM replacement, manufactured to the original equipment’s exacting specifications. The hose is constructed from high-grade EPDM rubber with a reinforced fabric layer, providing exceptional resistance to coolant chemicals, heat aging, and pressure fluctuations, ensuring long-term reliability under the extreme operating conditions typical of heavy-duty trucking.
This expansion tank hose (OEM WG9719530017) is essential for maintaining proper coolant levels, preventing air locks, and allowing the cooling system to self-bleed effectively. Its precise dimensions and pre-formed shape guarantee a perfect fit, while the smooth inner bore minimizes flow resistance. The WG9719530017 is built to endure the rigors of long-haul transport, off-road operations, and severe temperature variations, delivering dependable service over thousands of miles.
OEM direct replacement • High-grade EPDM rubber • Heat & coolant resistant • Precision pre-formed shape
The WG9719530017 Expansion Tank Hose is a key component of the engine cooling system, responsible for directing coolant overflow and returning it to the radiator as the system expands and contracts. It is engineered to replace original equipment hoses in SINOTRUK Howo trucks, ensuring proper coolant circulation, pressure balance, and air purge functionality. This genuine part is built to the highest standards, guaranteeing a perfect fit and reliable performance.
Constructed from a specially formulated EPDM compound with a high-strength textile reinforcement, the hose offers excellent resistance to ethylene glycol and other coolant additives, as well as ozone, ultraviolet radiation, and extreme temperatures. The inner tube is smooth and non-porous to prevent particle shedding and ensure unimpeded fluid flow, while the outer cover is designed to withstand mechanical abrasion and environmental exposure.
This expansion tank hose is essential for maintaining correct coolant levels, preventing overheating, and protecting the engine from thermal stress. Its robust construction and precise engineering guarantee reliable performance over extended service intervals, meeting the rigorous demands of heavy-duty trucking. It is the direct replacement you can trust to keep your SINOTRUK Howo cooling system operating efficiently.
The WG9719530017 Expansion Tank Hose is specifically engineered for SINOTRUK Howo heavy-duty trucks, including Howo A7, T7H, T5G, and other models that use this particular hose routing between the expansion tank and radiator. It is compatible with the standard neck connections and clamp sizes, making it the ideal replacement for maintaining cooling system integrity.
This hose is suitable for a wide range of applications, including long-haul trucking, regional distribution, construction, mining, and agricultural operations. Its robust construction and resistance to thermal cycling ensure reliable performance even under sustained high engine loads and extreme ambient temperatures.
When replacing, always verify the hose length, inner diameter, and routing shape to ensure a perfect match. The WG9719530017 is a direct-fit component that simplifies maintenance and restores optimal cooling system function.
Installing the WG9719530017 Expansion Tank Hose requires basic hand tools and safety precautions. Begin by allowing the engine to cool completely, then release the cooling system pressure by carefully opening the radiator cap. Place a drain pan underneath to catch any spilled coolant. Identify the old hose and remove the spring clamps or screw clamps securing it to the expansion tank and radiator connections.
Gently twist and pull the old hose off the fittings. Clean the connection nipples with a wire brush to remove any corrosion or debris. Compare the new hose to the old one to verify identical shape and length. Slide the new hose onto the fittings, ensuring it is fully seated and oriented correctly. Reinstall the clamps in their original positions and tighten them securely but not excessively. Refill the cooling system with the recommended coolant mixture and bleed any trapped air.
After installation, start the engine and allow it to reach operating temperature. Check for leaks at both connection points and verify that the expansion tank coolant level is correct. Regular maintenance includes visually inspecting the hose for cracks, bulges, or signs of coolant seepage. Replace the hose if it becomes hard, brittle, or shows any deterioration.
If any loss of coolant or pressure is observed, inspect the hose and clamps immediately. This hose is built to last, but regular checks ensure continued cooling system reliability.
This expansion tank hose is manufactured in an ISO 9001-certified facility using premium EPDM compounds and high-strength reinforcement yarns. The raw materials are tested for tensile strength, elongation, and hardness to ensure they meet strict performance criteria. Each hose is produced through a precision extrusion and molding process, guaranteeing consistent wall thickness and internal diameter.
We perform 100% visual inspection and dimensional verification on every hose, along with burst pressure testing on random samples to confirm that the hose can withstand at least 4 times its maximum working pressure. Additionally, we conduct heat aging and coolant immersion tests to simulate long-term service conditions, ensuring that the hose retains its flexibility and sealing properties over its entire service life.
Our commitment to quality ensures a reliable, leak-free connection, preventing coolant loss and engine overheating. Backed by a comprehensive warranty, this hose offers peace of mind for fleet operators and owner-operators.
