Product Details

The Four Seasons Complete A/C Kit line is organized to simplify major air conditioning service by grouping the compressor and related flow-control and moisture-management components in one application-specific package. Part number 3380NK is configured for Ford FS6 systems and is listed for factory air vehicles in the 1983-1987 range, including Ford Bronco, F-100, F-150, F-200, F-250, and F-350 applications. This kit is built around R134a refrigerant service and includes the specified compressor oil for system assembly.

This part cross-references Four Seasons 3380NK for the same application.

Common Problems This Kit Can Address

• Weak or inconsistent cabin cooling from a worn compressor
• Moisture contamination in the A/C system after component failure
• Restricted refrigerant flow caused by a worn or incorrect orifice tube
• Noisy compressor operation tied to internal wear
• System service needs after a major A/C component replacement

Installation Notes and Tips

Verify FS6 compressor fitment, factory air configuration, and the blue orifice tube requirement before installation. Replace the accumulator and O-rings during service, and follow the correct oil charge and evacuation procedures for R134a systems. Flush the system as needed when replacing failed components to reduce the risk of repeat contamination.

Quality Assurance

Four Seasons 3380NK is backed by a limited lifetime warranty.
