  Lower Hose – Subaru (45161GA770)

  The Lower Hose – Subaru (45161GA770) is a Genuine OEM coolant hose meticulously engineered by Subaru to meet exact factory specifications for the lower radiator circuit. Crafted from premium EPDM rubber reinforced with nylon fibers, this hose is built to withstand high pressure, extreme temperatures, and continuous exposure to coolant—ensuring enduring performance and engine protection.

  Designed for seamless compatibility with select Subaru models—including Forester, Outback, Crosstrek, and Legacy variants—the 45161GA770 matches the original hose in routing, bend geometry, and length. This precision ensures consistent coolant flow from the radiator’s lower outlet back to the engine water pump, maintaining optimal thermal balance without the need for trimming, splicing, or adapter fittings.

  Both professional technicians and DIY mechanics will appreciate the hose’s plug-and-play installation. Molded ends and factory bead ridges provide secure clamp engagement, reducing the risk of leaks, blowouts, or coolant loss under pressure. Subaru’s commitment to quality means this hose has been thoroughly tested for burst strength, cold-temperature flexibility, and chemical resistance.
