A/C Expansion Valve for Mercedes-Benz SLK and SLC

Global Parts 3412007 is an A/C expansion valve for select Mercedes-Benz SLK and SLC models. It regulates refrigerant flow before the evaporator so the system can use cooling capacity efficiently. This Global Parts 3412007 replacement is a direct-fit service part for common Mercedes-Benz SLK300, SLK350, SLK55 AMG, SLK250, SLC300, and SLC43 AMG applications.

Key Features

• Controls refrigerant flow into the evaporator
• Supports proper A/C system pressure management
• OE-style replacement for service and repair work
• Cross-references Four Seasons 39498 for the same application
• Part number: 3412007

Product Details

The expansion valve is a critical A/C flow restrictor that meters refrigerant before it enters the evaporator. By slowing refrigerant at the correct point in the system, it helps the evaporator absorb heat more effectively. Global Parts 3412007 is listed for Mercedes-Benz SLK and SLC platforms, including 2012-2016 Mercedes-Benz SLK250, 2015-2016 Mercedes-Benz SLK350, 2012-2016 Mercedes-Benz SLK55 AMG, 2016 Mercedes-Benz SLK300, 2017-2019 Mercedes-Benz SLC300, and 2017-2019 Mercedes-Benz SLC43 AMG.

What It Helps Address

• Weak cabin cooling performance
• Incorrect refrigerant metering at the evaporator
• A/C system service needs after component replacement
• Pressure irregularities related to flow restriction
• Reduced cooling efficiency in Mercedes-Benz SLK and SLC systems

Installation Notes

Replace the expansion valve during A/C service when the system is opened or repaired. Clean the system as required, verify refrigerant charge, and inspect related seals, lines, and the evaporator for contamination or wear before returning the vehicle to service. Confirm vehicle application by model year before installation. Part number 3412007 is used on select Mercedes-Benz SLK and SLC vehicles.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to help maintain proper refrigerant control and cooling performance.
