Dongfeng Xinjiang truck spare parts Engine water inlet hose 1303021-T5WF01Y

Built to support the engine’s cooling demand (critical for preventing overheating), this water inlet hose features a smooth internal structure that minimizes coolant flow resistance. The inner surface is extruded to a roughness of ≤0.4μm, reducing pressure loss by 15% compared to standard hoses—ensuring maximum coolant flow rate (120 L/min at 0.3MPa) to the engine. The hose’s inner diameter (45mm) is sized to match Dongfeng Xinjiang’s engine cooling system specifications, delivering sufficient coolant to high-heat components (e.g., cylinder heads, turbochargers) even during peak load (e.g., climbing slopes with full cargo). Pre-formed bends have a minimum radius of 60mm, avoiding kinking or constriction that could disrupt flow—maintaining consistent coolant circulation and keeping the engine within its optimal operating temperature range (82-95℃)

Engineered to endure the harsh conditions of the engine cooling system—including high temperatures and pressure—the hose delivers exceptional durability. It is constructed from a reinforced EPDM (ethylene propylene diene monomer) rubber composite with a polyester fiber braid layer, offering a continuous operating temperature range of -40℃ to 135℃ and a burst pressure rating of 2.5MPa—far exceeding the cooling system’s maximum working pressure (0.8MPa). The EPDM rubber resists degradation from ethylene glycol-based coolants (common in Dongfeng Xinjiang trucks), avoiding swelling, hardening, or cracking that could cause leaks. In thermal cycling tests (from -40℃ to 135℃, 500 cycles), the hose retains its flexibility and sealing performance, ensuring reliable operation in extreme weather—from freezing northern winters to hot desert summers

Designed to resist aging, chemical corrosion, and environmental damage, the water inlet hose maintains performance for extended service life. The EPDM rubber is formulated with anti-oxidants and UV stabilizers, preventing brittleness or discoloration from prolonged exposure to engine heat and sunlight (tested to 3000 hours of UV radiation with no performance loss). It is also resistant to diesel fuel, engine oil, and road chemicals, avoiding degradation from accidental spills or contact with adjacent components. The polyester fiber braid layer resists abrasion from engine vibration or contact with metal parts, maintaining structural integrity even after years of use. In accelerated aging tests, the hose shows no signs of leakage or flow reduction after 3 years of simulated use—ensuring a service life of over 5 years in real-world truck operations

Designed for hassle-free installation and reliable sealing, the hose features user-friendly design elements and secure connection points. End fittings are reinforced with 3mm-thick rubber collars, ensuring a tight seal with the engine water inlet and radiator outlet—compatible with standard hose clamps (included in optional installation kits). The hose’s flexibility (can bend up to 20° without permanent deformation) allows slight adjustments during installation to align with mounting points, eliminating the need for custom cutting or adapters. Installation steps are straightforward: slide the hose onto the barbed fittings, secure with clamps (torque to 8-10N·m), and check for leaks. No specialized tools are required, and a professional technician can complete installation in 20 minutes or less. The hose’s durable construction also reduces maintenance needs—minimizing truck downtime and lowering operational costs for fleet owners
