Product Details

Part number 891575 is an A/C compressor engineered around critical wear components, including the pulley, clutch, hub, bearing, and wobble plate. That design supports smooth operation under demanding conditions while helping maintain efficient refrigerant pumping and controlled operating noise. This part cross-references UAC CO10555JC for the same application.

Fits 1996-2001 Nissan Pathfinder, N/A. Fits 1997-2000 INFINITI QX4, N/A. For Nissan Pathfinder and INFINITI QX4 service work, confirm refrigerant oil handling before installation because the compressor is supplied with shipping oil only and must be drained and refilled to the correct specification.

Common Repair Uses

• Restores compressor function when the original unit has lost pumping efficiency.
• Addresses noisy operation from worn clutch, bearing, or pulley components.
• Helps correct weak or inconsistent air conditioning output.
• Replaces a compressor that no longer maintains proper refrigerant circulation.

Installation Notes

Verify R134A system compatibility, PAG 46 oil requirements, and connector fit before installation. Drain the shipping oil and refill with the correct oil quantity for the vehicle system. Confirm belt alignment, pulley groove match, and O-ring sealing surfaces during service.

Quality Assurance

Nissens manufactures compressors to OE standards and tests them for high-stress operation. The compressor design focuses on durability, pumping performance, and reduced noise and vibration for dependable HVAC service.
