Replace your plastic tank with a precision engineered aluminum upgrade by DaveFab. Compared to the OEM plastic reservoir, which is prone to failure over time, this TIG welded aluminum replacement won't wear out. Designed for your NC Miata, each new coolant expansion tank has been pressure tested for ultimate reliability. It utilizes the factory mounting points and hose. To install, simply remove the original and replace. Includes instructions, mounting hardware, an excellent glass sight gauge to check coolant levels, and radiator cap.


  • - Full TIG welded construction
  • - Fabricated from laser cut, CNC folded aluminum sheet
  • - Finished in signature satin-texture black

Note: This product is not compatible with aftermarket or Stant Radiator Caps. For optimum performance, we recommend using the OEM Mazda cap (108kpa / 16psi).
