Upper Radiator Expansion Tank Hose for BMW G80 — Overview

This is the upper coolant hose that runs between the radiator and expansion tank on the G80 M3. It is a basic replacement part in the cooling system, meant to fix leaks, cracked plastic ends, or a hose that has gone soft from heat cycles. If you are chasing a small coolant loss or see crusty residue around the hose connection, this is one of the first places I would check.

For a street-driven G80, this makes sense as a direct stock-style replacement when you do not need a full hose kit. It is the right call if one hose failed and the rest of the system still looks healthy. Just make sure the quick-connect ends lock fully in place and inspect the sealing surfaces before filling and bleeding the system.
