Product Details

This Nissens 891648 compressor is a direct replacement for the air conditioning compressor used on 2011-2012 INFINITI G25 models. It is designed for R134A systems and specified for PAG 46 oil, with an oil-filled configuration and included clutch assembly for service-ready installation planning. Nissens focuses on the compressor’s pulley, clutch, hub, bearing, and wobble plate to support smooth operation, reduced vibration, and durable performance under load. This part cross-references Monroe Shocks & Struts (e.g., CO29149RZ) for the same application.

What It Helps Fix

  • No cold air from the vents
  • Compressor noise or vibration during A/C operation
  • Weak refrigerant circulation in the HVAC system
  • Clutch engagement problems
  • Loss of cabin cooling performance on INFINITI G25 models

Installation Notes and Tips

Fits 2011-2012 INFINITI G25, N/A. Compressor filled with shipping oil only; drain and refill with the correct PAG 46 oil before installation. Verify refrigerant type, pulley alignment, connector fitment, and system cleanliness before charging the A/C system. Replace any damaged seals and evacuate the system according to service procedures after installation.

Quality Assurance

Nissens manufactures this compressor to OE standards and test-validates it for high-stress operating conditions. The design emphasis on key internal components supports consistent pumping performance and long-term durability in the INFINITI G25 HVAC system.
