Replace the failure-prone stock plastic coolant expansion tank on your 92-99 BMW 3 Series E36 with the Mishimoto aluminum version for added reliability and engine bay style. Constructed from durable TIG-welded aluminum, this tank withstands constant temperature cycles far better than OEM parts.

Key Features

  • TIG-Welded Aluminum Construction: Provides long-lasting strength against cracking and warping from heat and pressure cycles.
  • CNC-Machined Dipstick/Bleeder: Allows precise cold coolant level checks and easy air bleeding for optimal cooling system performance.
  • Direct-Fit Design: Bolts in place of OEM tank with no modifications, compatible with stock radiator and Mishimoto fan shroud.
  • Polished Finish: Delivers a clean, professional look that complements any engine bay build.
  • Direct replacement for OEM coolant reservoir, includes dipstick and O-ring seal.
  • Yes, direct fit for 1997-2002 BMW Z3 Roadster models with E36 chassis compatibility.
