Four Seasons 10141SK A/C Compressor Replacement Service Kit

Four Seasons A/C Installer Kit for Dodge Trucks

Four Seasons 10141SK is an A/C compressor replacement service kit built for R134a systems that need the core service components replaced together. It includes the filter drier, expansion valve, PAG 46 compressor oil, O-ring/gasket pack, and cap and valve kit for a more complete A/C repair on select Dodge D150, D250, D350, W150, W250, W350, and Ramcharger applications.

The Four Seasons A/C Installer Kits line is aimed at compressor replacement service work, combining the parts commonly addressed during an A/C overhaul. This kit is configured with a block-type expansion device, an O-ring inlet, and a flange outlet, and it uses pad-mount receiver drier/accumulator connections sized at 0.375 in. inlet and outlet.

Common repair applications

• Restoring cooling performance after compressor replacement
• Replacing a restricted or contaminated filter drier

• Servicing R134a A/C systems on Dodge D250, D350, and Ramcharger trucks

Installation notes and tips

Before charging the system, verify the vehicle’s A/C layout and confirm the receiver drier/accumulator pad-mount connection dimensions match the existing setup. Replace the expansion valve and drier during compressor service, evacuate the system thoroughly, and use the specified PAG 46 oil amount for the application. Clean all sealing surfaces and replace any disturbed O-rings and gaskets during reassembly.

Quality assurance

Four Seasons 10141SK carries a limited lifetime warranty. The kit is built for service replacement on confirmed Dodge truck and Ramcharger applications and is intended to support a complete A/C repair workflow using the listed components and refrigerant specification.
