What It Helps Address

• Coolant loss from a cap that no longer seals properly
• Pressure-related cooling system instability
• Expansion tank cap wear or deterioration
• Incorrect cap fitment on specified Mini Cooper and Freelander applications
• Service replacement for OE-numbered cooling system caps

Installation Notes and Tips

Confirm the existing cap’s pressure rating, dimensions, and OE number before installation. Match the application to the expansion tank location and verify chassis/VIN notes for Land Rover Freelander models. Inspect the sealing surfaces on the tank neck and cap before fitting the new radiator cap.
