Add some additional reliability and engine bay styling with the Mishimoto BMW E36 Aluminium 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 aluminium 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. It features a polished finish that will look great in your engine bay. This expansion tank is a direct fit for the stock and Mishimoto BMW E36 Performance Fan Shroud Kit! As with all our products, this expansion tank includes the Mishimoto Lifetime Warranty.

When the BMW E36 launched in 1990, it quickly earned a reputation for its balance of performance, handling, and everyday usability. Its lightweight chassis and smooth inline-six engines made it a standout in the compact executive car segment. Over the course of its production, BMW expanded the lineup to include sedans, coupés, convertibles, wagons, and hatchbacks, all built on the same driver-focused platform.
More than two decades later, the E36 continues to maintain a strong following in the automotive world. Its combination of sharp handling, solid construction, and a simple, modifiable engine bay makes it a platform that appeals to enthusiasts and daily drivers alike. Owners value the E36 not just for its performance potential but also for its reliability, ease of maintenance, and the satisfaction of working on a car that rewards both care and upgrades.
