MAX NOLOGY VW Phaeton Coolant Expansion Tank Cap Cover, Black is a direct replacement cap designed for VW Phaeton models from 2008 to 2016. Built to OEM standards (OEM No. 3D0121321B) with a robust plastic and rubber body, it helps maintain correct cooling system pressure, prevents coolant leaks, and protects engine components from contamination. The black color matches most engine bays and delivers a clean, factory-finish look.

This cap is 100% new and ready for installation. By restoring the seal on the expansion tank, it reduces the risk of overheating and ensures reliable engine performance between services.

Benefits & Tips

  • Significant reduction in coolant loss by maintaining proper pressure in the expansion tank.
  • Simple, direct replacement that preserves OEM fit and function—no special tools required.
