KARPAL Expansion Tank Kit for BMW E90 — Overview

This is a replacement coolant expansion tank kit for E90 3 Series cars, bundled with the level sensor and cap. It cross-references BMW part numbers 17137607482, 17137567462, and 17137640514, so it covers the usual wear items in one shot instead of piecing it together. On these cars, old tanks get brittle from heat cycling and start seeping or cracking around the seams, so replacing the whole setup makes more sense than chasing one failed piece at a time.

I’d pick this if your original tank is leaking, the level sensor is acting up, or the cap is old enough that you don’t trust it anymore. For a budget-minded E90 refresh, having the sensor and cap included is the main advantage over buying a bare tank. Just make sure the part numbers match your specific car before ordering, because E90 cooling system variations can depend on engine and production date.
