Four Seasons 3138NK A/C Compressor and Component Kit

Complete A/C Kit for Ford F-150 and F-250

Four Seasons 3138NK is a complete air conditioning kit with a new compressor for select 2007-2008 Ford F-150 and F-250 applications, plus 2007-2008 Lincoln Mark LT models with the FS20 compressor. It is built for R134a systems and includes the core components needed to restore A/C operation in one service package.

The Four Seasons Complete A/C Kit line is organized to simplify major HVAC repairs by grouping the compressor, accumulator, orifice tube, oil, and sealing components into one matched kit. For Ford truck owners, that means a more direct path to servicing a worn or failed air conditioning system without piecing together separate parts.

• Complete A/C compressor kit with a new compressor
• Includes compressor oil and O-rings
• Uses an orifice tube expansion device
• R134a refrigerant system application
• Accumulator features P-nut inlet fitting and male springlock outlet fitting
• Limited lifetime warranty

Detailed Product Overview

This Four Seasons 3138NK kit includes 68192 new compressor, 83364 accumulator, 38635 orifice tube, 59007 oil, and O-rings. The orifice tube is a standard red tube with a .062 in. diameter, and the accumulator measures 3.500 in. in diameter and 9.000 in. in length. It is a practical choice for restoring refrigerant flow and system balance in Ford F-150, Ford F-250, and Lincoln Mark LT HVAC systems that use the FS20 compressor.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Kit Helps Address

• Loss of cabin cooling from a failed compressor
• Restricted refrigerant flow caused by a worn or incorrect orifice tube
• Moisture control issues related to an aging accumulator
• Leaking seals at service points in the A/C system
• System noise or poor performance tied to compressor wear

Installation Notes and Tips

Verify FS20 compressor fitment before ordering, especially on 2007-2008 Ford F-150, 2007-2008 Ford F-250, and 2007-2008 Lincoln Mark LT applications. Replace the accumulator and orifice tube during compressor service, and evacuate and recharge the system with the correct R134a procedure after installation. Confirm line fitting style and refrigerant oil requirements before final assembly.

Quality Assurance

Four Seasons 3138NK is backed by a limited lifetime warranty.
