Dongfeng xinjiang truck spare parts Engine-end water outlet hose 1303226-T5M301Y

Built to withstand the harsh operating environment of truck engines, this water outlet hose features a heat-resistant rubber core that operates reliably across a temperature range of -40℃ to 135℃. It resists softening, cracking, or deformation even when exposed to high-temperature engine coolant (up to 120℃) for prolonged periods. The hose’s burst pressure rating reaches 1.6MPa—exceeding the engine cooling system’s maximum working pressure (0.8-1.0MPa)—preventing rupture under pressure spikes. Its multi-layer structure (inner rubber + reinforcement layer + outer rubber) enhances pressure resistance, ensuring stable coolant flow from the engine to the radiator. This robust performance is critical for preventing engine overheating during heavy loads or long-haul driving

The hose incorporates a precision-molded connector with a built-in sealing lip (shore hardness: 70±5) that forms a tight seal with the engine’s water outlet port. The sealing lip is made of nitrile rubber (NBR) with excellent oil and coolant resistance, preventing leakage even under vibration or temperature fluctuations. Additionally, the hose’s connector is reinforced with a stainless steel clamp groove, allowing the factory clamp to fasten tightly without slipping. The inner surface of the hose is smooth, reducing coolant flow resistance and avoiding sediment accumulation that could compromise sealing. This leak-proof design maintains the cooling system’s pressure and coolant level, preventing engine damage from overheating or coolant loss

Constructed from high-quality EPDM (ethylene propylene diene monomer) rubber, the hose offers superior resistance to coolant, oil, ozone, and UV radiation—avoiding degradation from chemical exposure. The inner rubber layer is specially formulated to resist swelling or hardening when in contact with ethylene glycol-based coolants (common in truck engines). The middle reinforcement layer is made of high-strength polyester fiber braid, enhancing tensile strength (≥15MPa) and preventing the hose from expanding under pressure. The outer rubber layer features anti-abrasion treatment, resisting scratches from engine bay components. These materials ensure the hose’s service life exceeds 50,000 kilometers, reducing replacement frequency and maintenance costs

Designed for user-friendly installation, the hose’s flexible EPDM material allows easy bending to match the engine bay’s layout—no specialized tools or heating are required. The pre-cut length and precise connector shape enable direct alignment with the engine’s water outlet and radiator inlet, simplifying the replacement process. Installation steps are straightforward: remove the old hose’s clamps, detach the worn hose, align the new hose’s connectors with the ports, and re-fasten the clamps to the recommended torque (12N·m). The entire process takes less than 20 minutes for a professional technician. Maintenance is equally simple—regular visual inspections for cracks or leaks are sufficient, as the hose’s durable materials resist routine wear. This design minimizes truck downtime, ensuring quick return to service
