Detailed Description

Four Seasons 5361N is a PAC-Kit w/ New Compressor built for factory air systems on select Ford Mustang, Ford Thunderbird, Ford Cougar, Mercury Capri, and Mercury Cougar models. The fitment data identifies both FS6 and 6E171 compressor configurations, along with vehicle-specific notes such as 6-groove pulley requirements and production cutoffs like from 5/85 or to 1/86. For shoppers searching for a Ford Cougar A/C compressor kit or a Mercury Capri compressor replacement, this part number provides a direct match to the listed applications.

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

Common Repair Uses

• Restoring cooling performance when the original compressor is worn or no longer operating correctly
• Addressing A/C noise, seizure, or compressor drag in factory air systems
• Replacing a compressor on 1983-1986 Ford and Mercury vehicles with FS6 or 6E171 setups
• Correcting fitment issues tied to pulley style or production-date-specific compressor changes
• Supporting service work on Ford Mustang, Thunderbird, Cougar, and Mercury Capri/Cougar A/C systems

Installation Notes and Tips

Verify the compressor type, pulley configuration, and production date before ordering. Match the vehicle’s factory air setup and confirm whether the application calls for FS6 or 6E171 compressor fitment. Follow standard A/C service procedures, including system flushing and proper oil handling, before installing the new compressor.

Quality Assurance

Four Seasons is a recognized aftermarket brand in HVAC service parts, and the 5361N PAC-Kit w/ New Compressor is cataloged for specific OE-style applications rather than universal use. Confirm all fitment notes against the vehicle before installation.
