BMW 1/3 Series Upper Radiator Coolant Hose | Fits E88, E90, E92 125i 128i 130i 325i 328i 330i | OEM Part No. 17127531579

Your BMW’s cooling system depends on a properly sealed and structurally sound upper radiator hose to keep engine temperatures stable. Over time, the factory hose becomes brittle, cracked, swollen, or leaks at the quick-connect fittings, leading to overheating, coolant loss, and potential engine damage.

This OEM-quality Upper Radiator Coolant Hose (Part No. 17127531579) is the correct replacement for a wide range of E8X and E9X BMW models. Designed to match BMW’s original fitment and routing, it connects the radiator to the thermostat/water outlet, ensuring efficient coolant flow throughout the engine.

Manufactured with high-temperature rubber, factory-correct quick-connect ends, and reinforced walls, this hose is engineered to withstand extreme heat cycles while delivering long-term reliability. Replace your aging, leaking, or swollen hose before it leads to major cooling system failure.
