Product Details

Nissens 890199 is an A/C compressor engineered for Mercedes-Benz HVAC systems that require a 7SEU17C compressor with R134A refrigerant. Nissens develops thermal and engine efficiency components for aftermarket use, and this compressor follows that approach with application-specific fitment and OE-style service characteristics. If you are replacing a worn compressor on a Mercedes-Benz CL550, S550, or AMG model, this unit is built around the listed vehicle applications and factory-style refrigerant specifications.

This part cross-references Monroe Shocks & Struts (e.g., ACP891000P, ACP913000P) for the same application.
