M52/M54 Heavy Duty Expansion Tank Kit – E46, E53, E83

Product Details

Our Turner Motorsport’s full aluminum expansion tank was designed and engineered in house to help with the weak point in your M52/M54 cooling system. The coolant expansion tank goes through heat cycles over and over again from regular driving, it is important that your expansion tank is doing its job to retain coolant to keep your engine operating temperatures down and keep your engine bay clean. Not only is this a major upgrade but also a great maintenance item to replace. Our expansion tank was designed to fit the OEM hoses for an easy install and comes with all the upgraded items you will need for a clean install.

If your BMW needs a new expansion tank, make sure this is the last expansion tank you ever need to buy.
