Leak-Proof Aluminum Radiator Coolant Reservoir Pressure Tested Tank for BMW F92 M8 F90 M5

Silver Aluminum Coolant Expansion Tank for BMW M5 / M8

This CNC aluminum coolant expansion tank is listed for BMW F90 M5 and F91/F92/F93 M8 models with the S63 4.4L twin-turbo V8. The original package list identifies a silver pre-assembled tank intended for use with the vehicle's existing pressure cap.

Product details

• One silver CNC aluminum coolant expansion tank
• Pre-assembled housing with internal seals described in the original listing
• Pressure cap is not included; check compatibility before reusing the original BMW cap

Fitment check: Verify the original tank part number, mounting-hole spacing, hose connections and cap specification for your particular vehicle. The previous listing specifically asks M8 owners to check bracket center-hole spacing. The tank is not a guarantee against leaks or a substitute for correct installation and cooling-system inspection. Do not dismantle the pre-assembled housing without appropriate service guidance.
