Luxury Gold CNC Billet Aluminum Coolant Expansion Tank for BMW F90 M5 F92 M8 S63 4.4T V8 Engines Reuses OEM Cap

CNC Aluminum Coolant Expansion Tank for BMW M5 / M8

An aluminum coolant expansion tank listed for BMW F90 M5 and F91/F92/F93 M8 models with the S63 4.4L twin-turbo V8. Its machined housing and external coolant-level sight tube offer a different engine-bay look from the original plastic tank while allowing a visual level check.

Product details

• One pre-assembled CNC aluminum coolant expansion tank
• External coolant-level sight tube described in the original listing
• Pressure cap is not included; the listing calls for reuse of the original BMW cap

Before ordering: Check your vehicle's original tank part number, mounting-hole spacing, hose connections and pressure-cap compatibility. The previous listing especially calls for checking bracket spacing on M8 models. Its color descriptions conflict (gold/black in one section, black/silver in the package list), so confirm the exact finish before purchase. Do not open the pre-assembled housing unless directed by qualified service instructions.
