Detailed Description

Nissens part number 891707 is an A/C compressor engineered for Mercedes-Benz GL350 and Mercedes-Benz ML350 vehicles that use R134A refrigerant. The compressor design focuses on the critical rotating components, including the pulley, clutch, hub, bearing, and wobble plate, to support consistent refrigerant pumping, controlled noise levels, and long service life under demanding operating conditions. This part cross-references Monroe Shocks & Struts (e.g., CO11382Z) for the same application.

Fits 2013-2014 Mercedes-Benz GL350, N/A. Fits 2012-2014 Mercedes-Benz ML350, N/A. Part number 891707 is a practical OE-style replacement when the original compressor is noisy, weak, or no longer maintaining proper system pressure.

What It Helps Address

• Warm air from the vents when the compressor is no longer circulating refrigerant effectively
• Unusual compressor noise, vibration, or pulley-related operation issues
• Loss of A/C performance caused by worn internal compressor components
• Clutch engagement problems in the air conditioning system
• System sealing concerns at compressor connection points

Installation Notes and Tips

Before installation, drain the shipping oil and refill the compressor with the correct amount and type of PAG 46 oil for the vehicle system. Verify refrigerant type, belt routing, connector fitment, and pulley alignment before charging the system. Replace any contaminated refrigerant components as needed and evacuate the system properly before recharging.

Quality Assurance

Nissens manufactures this compressor to OE-level standards and validates it for high-stress operating conditions. The design emphasis on pumping efficiency, reduced vibration, and durable rotating components supports consistent performance in Mercedes-Benz GL350 and ML350 applications.
