Billet Aluminum Expansion Tank - E39 M5

BILLET ALUMINUM Expansion Tank with an OE Level Sensor

The wait is finally over. Euro Power Motorsports in collaboration with EAE is proud to introduce the all-new BMW E39 M5 Billet Aluminum Coolant Expansion Tank for the E39 M5. EAE Motorsports has taken on the initiative to design, prototype, create, and manufacture a Coolant Expansion Tank for the BMW E39 M5. The original plastic tank becomes frail over time and cracks which causes a multitude of problems — especially on the track. Once the tank fails, it can become a costly repair bill that is inconvenient and troublesome. Let alone the ugly discoloration that we have to look at every time we open our hoods and see the once-upon-a-time clear tank that has turned into a nasty yellow color.

With the Coolant Expansion Tank from EAE Motorsports, you will have peace of mind that it will never crack or leak, and it will always look beautiful. Made out of strong 6061 T6 Billet Aluminum, the Coolant Expansion Tank is proven to last a lifetime without any headaches or worries — no matter if you’re on the street or on the track. You will also have the option of anodizing to a color of your choice. Finally, EAE offers a Lifetime Warranty on all its products. So you’ll never have to worry about buying a new Expansion tank again.

This part is a replacement for BMW part number 17112229114 (17-11-2-229-114) for all E39 M5.
