Hack Engineering Aluminium Coolant Tank (E30/E36 inc M3)
Hack Engineering Aluminium Expansion Tank to replace BMW part number 17111712641, as found on E30 M20/M21 models, E36 M3 3.0/3.2 models and Z3 M S50 models.
These tanks are hand-made from aluminium and TIG-welded, coming with integrated brackets perfectly fit either the E30, or to fit the E36/Z3. A bolt-on upgrade to replace the unsightly and potentially brittle original plastic tank. Includes polished cap.
Please note these tanks do not include a provision for an OE level sensor. This can easily be deleted.
