Mishimoto Aluminum Coolant Expansion Tank, BMW E36 1303508 and supercharged applications by resistingAdd some additional reliability and engine bay styling with the Mishimoto BMW E36 Aluminum Coolant Expansion Tank. Stock coolant expansion tanks are prone to failure after years of constant temperature variations. The Mishimoto tank is constructed from durable, TIG welded aluminum for optimal durability and longevity. The engineers at Mishimoto have designed a CNC machined dipstick which doubles as a bleeder and allows for proper cold coolant levels.
