Detailed Description

Four Seasons 6635R is an A/C compressor kit intended for select Mercedes-Benz CL-Class and S-Class vehicles. The PAC-Kit w/ Reman Compressor line groups the remanufactured compressor with the related service parts identified in the fitment notes, including the filter drier, expansion valve, flush, and oil references. This makes it a practical choice when replacing a failed compressor and restoring system operation on Mercedes-Benz CL550, S500, and related applications.

Fitment coverage includes 2007-2014 Mercedes-Benz models, with notes that distinguish compressor type and rear A/C configuration where required. Use the exact vehicle listing and compressor code to confirm application before ordering. Part number 6635R appears in the catalog as the reference for this PAC-Kit configuration.

What It Helps Address

• Loss of cabin cooling from compressor failure.
• Noisy or seized compressor operation.
• System contamination after compressor breakdown.
• Incorrect compressor match for the vehicle’s A/C configuration.
• Service delays when related A/C components are sourced separately.

Installation Notes

Verify the compressor code, model year, and any rear A/C or front-position notes before installation. Follow standard A/C service procedures, including system evacuation, flushing where required, and proper oil handling based on the vehicle’s service specifications. Confirm all fitment details for Mercedes-Benz CL-Class and S-Class applications before beginning the repair.

Quality Assurance

Four Seasons supplies aftermarket climate control components for service and replacement applications. This kit is identified by part number 6635R and the PAC-Kit w/ Reman Compressor line designation for catalog accuracy.
