  Engine Coolant Reservoir Hose – Subaru (45162AE020)

  The Engine Coolant Reservoir Hose – Subaru (45162AE020) is a Genuine OEM component engineered by Subaru to match the exact specifications of the factory cooling system. Crafted from high-quality EPDM rubber with reinforced layers, this hose is designed to accommodate coolant flow between the radiator and reservoir under varying temperature and pressure conditions, while resisting heat, chemicals, and mechanical stress.

  Built for precise compatibility with select Subaru models—such as Impreza, WRX, Baja, Forester, and Legacy—the 45162AE020 closely mirrors the original hose in length, bends, and diameter. This exact match ensures seamless integration with existing reservoir necks, radiator fittings, and clamp placement, providing plug-and-play functionality without the need for trimming, rerouting, or custom adapters.

  This OEM hose benefits both professional mechanics and skilled DIYers. Its factory-molded shape aligns perfectly with vehicle layout, making installation quick and accurate, reducing downtime in busy service environments or personal garages. The hose’s durable construction resists expansion and cracking and is tested to endure thermal cycling, pressure fluctuations, and coolant exposure over prolonged use.

  • Genuine OEM Subaru hose ensures perfect factory fit and system compatibility

  • Reinforced EPDM rubber resists heat, pressure, and coolant aging

  • Molded bends and precise dimensions provide plug-and-play installation

  • Secures reliably with OEM-style clamps for leak-free performance

  • Ideal for professional repair shops and home-garage DIY maintenance

  • Maintains correct coolant reservoir flow and engine thermal protection

  Proper coolant overflow and return are essential to maintaining system integrity. With the 45162AE020, excess coolant can safely travel to the reservoir when hot and return under vacuum as the system cools. Using this OEM hose ensures that the cooling circuit operates as Subaru engineered—with stable pressure, balanced coolant volume, and reduced stress on the radiator, reservoir, and engine.

  Whether you're performing scheduled maintenance or replacing worn parts, the Engine Coolant Reservoir Hose – Subaru (45162AE020) offers reassurance and precision engineering. It's an essential element for preserving cooling system performance and engine longevity, delivering peace of mind mile after mile.
