Add 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. 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.

After a few hot and cold cycles, Mishimoto recommends checking the dipstick to confirm a proper cold coolant level. It is critical that the dipstick is not removed when the engine coolant is hot. You must wait until the coolant is cold before removing.
