E46 Mishimoto Aluminum Coolant Reservoir Tank (NO LONGER AVAILABLE)
If you have ever experienced a leaking plastic BMW expansion tank you will realize the value of this aluminum version straight away. Even if a failure has not happened to you, it's easy to tell this tank is much stronger and more durable than the plastic used in the stock design. Mishimoto has extended their cooling system expertise from aluminum radiators to expansion tank design. The original BMW plastic tanks suffer from leaks and failures with no warning. While being light weight and recyclable the design and construction of the stock tank is just not up for reliable long term use. Mishimoto has designed their tank with an integrated dipstick/bleeder and a 1.3bar cap that raises the boiling point of the system (the stock radiator cap is not compatible).
The Mishimoto expansion tank takes the place of the stock tank in the stock plastic radiator fan shroud or in the Mishimoto electric fan and shroud upgrade. It takes the stock coolant level sensor and the upper and lower hoses as well.
Lifetime warranty!
