Product Overview

Nissens part number 891664 is a direct-fit style A/C compressor for vehicles using R134A refrigerant and PAG 46 oil. The compressor’s pulley, clutch, hub, bearing, and wobble plate are designed to support smooth operation, controlled noise, and dependable durability under high-load HVAC conditions. This makes it a practical replacement for Infiniti Q50 and Q60 models, as well as the Nissan 370Z, when the original compressor is worn or no longer maintaining proper system pressure.

This part cross-references UAC CO29197C for the same application.

Common Problems This Compressor Can Address

Installation Notes and Tips

Before installation, drain the shipping oil and refill the compressor with the correct amount and type of oil for the vehicle system. Verify R134A refrigerant compatibility, confirm the 7-groove serpentine belt setup, and replace the included O-rings during installation. Always inspect the A/C system for contamination, leaks, and proper evacuation before charging.
