Detailed Description

This Valeo compressor is engineered as a matching-quality replacement for Mercedes-Benz HVAC systems that require the 7SEU configuration and 170 ml oil capacity.

What It Helps Fix

• Compressor replacement needs after seizure, leakage, or mechanical failure
• Restoration of proper A/C operation on Mercedes-Benz HVAC systems

Installation Notes and Tips

Verify the vehicle uses R134a refrigerant and PAG 46 oil before installation. Confirm the 6-groove pulley, female connector, and 7SEU compressor type match the original unit. Follow the included installation instructions and use the specified 170 ml oil capacity during service. Always inspect the system for contamination, leaks, and related component wear before charging the A/C system.
