This specific-fit, aluminum parallel flow condenser is built for select Mercedes-Benz CL-Class and S-Class applications, including 2011-2014 Mercedes-Benz CL600 and 2011-2014 Mercedes-Benz CL63 AMG models with shroud.

Global Parts 3778C is a direct replacement for vehicles that need efficient refrigerant heat rejection and stable A/C operation. It is a practical choice when servicing a Mercedes-Benz CL550, CL600, CL63 AMG, S450, S550, or S600 with the correct factory-style condenser layout.

Key Features

• Aluminum core construction for lightweight heat transfer performance
• Parallel flow condenser core type for efficient refrigerant cooling
• Specific fit design for select Mercedes-Benz applications
• Block inlet fitting type for factory-style connection
• No oil cooler included
• No drier or desiccant included

Product Details

The Global Parts 3778C condenser removes heat from refrigerant after it leaves the compressor, helping the A/C system return cooled air to the cabin. On many vehicles, condensers are not serviceable by cleaning or flushing, so replacement is the standard repair path when the unit is restricted, damaged, or contaminated. For Mercedes-Benz CL600 and related models, this condenser supports a proper OE-style repair with the correct fitment and connection style.

This part cross-references Four Seasons 73778 and UAC CN3778PFC for the same application. Global Parts 3778C also aligns with common replacement searches for Mercedes-Benz CL550 condenser, Mercedes-Benz S550 A/C condenser, and Mercedes-Benz CL63 AMG condenser replacement.

What It Helps Fix

• Weak or warm A/C air from poor refrigerant heat removal
• Leaks caused by condenser damage or corrosion
• Restricted airflow through a clogged condenser core
• System contamination after compressor failure
• Improper cooling performance in select Mercedes-Benz CL-Class and S-Class vehicles

Installation Notes

Replace the condenser when the system has been opened for major A/C repair, especially after compressor failure. Verify block inlet connection style, shroud requirements, and vehicle-specific fitment before installation. Because condensers cannot usually be cleaned or flushed effectively, confirm the rest of the system is free of debris before reassembly. Professional A/C service procedures, evacuation, and recharge are recommended.

Quality Assurance

Global Parts 3778C is built as a specific-fit replacement condenser for the listed Mercedes-Benz applications. The aluminum parallel flow design supports efficient heat exchange and factory-style serviceability for a proper A/C repair.
