Upper Coolant Reservoir Hose for BMW F82 — Overview

This is the upper coolant reservoir hose, the small line that connects the expansion tank into the cooling system. It replaces BMW part 17127535527 and is listed here for F82 fitment. If your original hose is brittle, sweating coolant at the ends, or the plastic connection looks tired from heat cycles, this is the straightforward fix.

I’d pick this over trying to reuse an old hose once you’re already in there chasing a coolant smell or a slow leak. On BMWs, these plastic quick-connect cooling pieces do not get better with age, and disturbing them during other work is usually what finishes them off. Best time to replace it is when you’re already servicing nearby cooling parts and want to avoid doing the job twice.
