Fits 1992-2002 BMW 3 Series (323i, 323is, 325i, 325is, 328i, 328is, M3) and 1997-2002 Z3 (Roadster, Coupe, M models).

Replace your BMW's failure-prone factory plastic coolant tank with the Mishimoto Aluminum Coolant Expansion Tank. Standard OE expansion tanks are notorious for cracking and leaking after years of heat-cycling and pressure variations. This Mishimoto upgrade is engineered for long-term durability, utilizing 100% TIG-welded aluminum to eliminate the common failure points associated with plastic units.

This tank features a CNC-machined dipstick that doubles as a bleeder, ensuring you can maintain proper cold coolant levels and purge air from the system with ease. Designed as a direct bolt-on, it integrates perfectly with the stock setup or the Mishimoto BMW E36 Performance Fan Shroud Kit. The polished finish provides a clean, professional look under the hood while providing superior reliability on the street or track.
