The 3697436F Bypass Water Hose is a specialized OEM cooling system component engineered exclusively for diesel engines, covering a wide range of applications including heavy-duty on-highway vehicles (long-haul trucks, urban buses), off-highway machinery (construction excavators, mining loaders, agricultural tractors), and stationary industrial generators.
As a critical part of the engine's coolant circulation system, its core function is to create a "bypass" pathway for engine coolant—directing a portion of the fluid around the radiator during cold starts or low-load operations, accelerating engine warm-up to reach optimal operating temperature (82-95°C) faster, and preventing overcooling that could reduce fuel efficiency or cause component wear.




We are a comprehensive and diversified enterprise specialized in diesel generator sets, engine assemblies, and genuine parts sales. We provide a full range of after-sales services to ensure stable equipment operation. Our technical expertise covers various construction machinery, providing professional maintenance and solving complex equipment failures to ensure normal production for our clients.
