Installation Notes and Tips

Confirm OE number A2722000031 and verify rear-position fitment before installation. This part cross-references Mercedes-Benz OE number A2722000031 for the same application. Use the vehicle’s service information to inspect coolant routing, electrical connections, and system bleeding procedures after replacement. For Mercedes-Benz C300, E350, and ML350 rear HVAC repairs, matching the original valve configuration is important for proper operation.
