Black and Silver Aluminum Coolant Expansion Tank for BMW M5 / M8

Product details

• One pre-assembled CNC aluminum coolant expansion tank, black and silver as listed
• Original listing describes a sealed housing with internal O-rings
• Pressure cap is not included; the listing calls for reuse of the original BMW cap

Before ordering: Compare your original tank part number, hose locations, mounting-hole spacing and pressure-cap specification. In particular, confirm M8 bracket center-hole spacing. The material does not by itself guarantee a leak-free cooling system; correct fitment, installation and routine inspection remain essential. Do not dismantle the pre-assembled tank without appropriate service guidance.
