Product Details

The Four Seasons 4194NK Complete A/C Kit is a complete air conditioning kit with a new compressor for Volkswagen models using the SD7V16 compressor platform. It is built around the core service components needed for a compressor replacement, including the compressor, filter drier, expansion valve, oil, and sealing O-rings. This makes it a practical choice for Volkswagen Beetle, Volkswagen Jetta, Volkswagen Beetle Cabrio, and Volkswagen Clasico A/C repairs where the original system uses R134a refrigerant.

This part cross-references 520574 and MK1068 for the same application. The 4194NK kit is a fitment-based solution for Volkswagen A/C service, especially when replacing a worn compressor and related system components at the same time.

What It Helps Fix

• Weak or inconsistent cabin cooling
• Noisy or failing A/C compressor operation
• Restricted refrigerant flow from a worn expansion valve or filter drier
• Refrigerant leaks at service connections and sealing points
• System contamination after compressor failure

Installation Notes and Tips

Verify the vehicle uses an SD7V16 compressor before ordering. Confirm R134a refrigerant system requirements and match the compressor pulley and connection style to the original setup. Replace the filter drier and expansion valve during compressor service, and evacuate and recharge the system according to factory procedures after installation.

Compatible fitment includes 2011-2015 Volkswagen Clasico, 2005-2010 Volkswagen Beetle, 2010 Volkswagen Beetle Cabrio, 2003-2005 Volkswagen Jetta, 1999-2000 Volkswagen Jetta, 1998-2004 Volkswagen Beetle, and 2002 Volkswagen Jetta, all with SD7V16 compressor applications as noted.
