Detailed Description

What This Part Helps Address

• Loss of cabin cooling from a leaking evaporator core
• Restricted airflow through a corroded or internally damaged core
• Refrigerant odor or residue from evaporator failure
• Inconsistent A/C performance caused by a compromised heat exchanger
• HVAC service needs on select Volkswagen Cabriolet, Jetta, Rabbit Convertible, and Rabbit Pickup models

Installation Notes and Tips

Verify the core width, height, depth, and fitting orientation before installation. Match the No. 8 female O-ring inlet and No. 10 male insert O-ring outlet to the vehicle’s refrigerant lines, and inspect the HVAC case, seals, and O-ring sealing surfaces during service. Because this is an internal HVAC component, careful handling helps protect the aluminum fins and preserve airflow through the core.
