A/C Suction Hose for Mercedes-Benz ML-Class

Global Parts 4814136 is an A/C refrigerant suction hose for the low-side circuit. It routes refrigerant from the compressor to the evaporator, helping maintain proper airflow temperature control in the HVAC system. This part is compatible with Mercedes-Benz ML350 and ML320 applications listed below.

Key Features

• Part number: 4814136
• Category: HVAC hose and pipe replacement
• Low-side suction hose for the compressor-to-evaporator path
• Direct fitment for select Mercedes-Benz ML350 and ML320 models
• Cross-reference: Four Seasons 66858

Product Details

This Global Parts A/C refrigerant suction hose is built for the low-pressure side of the air conditioning system. In the HVAC layout, suction hoses carry refrigerant from the compressor to the evaporator, while discharge hoses move refrigerant from the compressor to the condenser. For Mercedes-Benz ML350 and Mercedes-Benz ML320 vehicles, the correct hose routing is critical for stable A/C performance and proper refrigerant flow. Part number 4814136 is listed for 2003-2005 Mercedes-Benz ML350 and 1998-2003 Mercedes-Benz ML320 applications.

Common Issues This Part Can Address

• Low-side refrigerant leakage at the suction hose
• Reduced A/C cooling performance
• Damaged or deteriorated hose routing in the compressor-to-evaporator line
• Loss of refrigerant pressure in the HVAC system

Installation Notes and Tips

Verify the vehicle year, model, and hose routing before installation. Inspect mating connections, seals, and adjacent A/C components for wear or contamination before replacing the hose. After installation, evacuate and recharge the system according to factory service procedures and check for leaks.

Quality Assurance

Global Parts 4814136 is cataloged as an OE-style replacement for the specified Mercedes-Benz ML350 and ML320 fitments. It cross-references Four Seasons 66858 for the same application.
