Detailed Description

Nissens Part Number 891592 is an A/C compressor designed for replacement use in passenger vehicle HVAC systems that rely on R134A refrigerant. Its SD7H15 compressor architecture, 4.75-inch pulley diameter, and 8-groove serpentine belt drive support consistent belt engagement and smooth operation. Nissens focuses on critical wear components such as the pulley, clutch, hub, bearing, and wobble plate to help maintain pumping efficiency and control noise and vibration.

This compressor is a practical choice for service work on vehicles such as Honda Civic and Toyota Camry applications where OE-style fit and function are required. If you are replacing a worn compressor on a Honda Civic or Toyota Camry, Part Number 891592 provides a direct-service HVAC component built around standard refrigerant and oil specifications.

This part cross-references UAC (e.g., CO4672, CO7822C) for the same application.

What It Helps Fix

• Weak or inconsistent cabin cooling
• Noisy compressor operation
• Excessive A/C system vibration
• Compressor seizure or internal wear
• Loss of refrigerant circulation in the HVAC system

Installation Notes and Tips

Verify the vehicle uses R134A refrigerant and PAG 100 oil before installation. Confirm pulley groove count, connector style, and compressor type match the original unit. Replace the O-rings during service, evacuate and recharge the system correctly, and inspect the belt drive and related A/C components for wear before returning the vehicle to service.

Quality Assurance

Nissens manufactures this compressor to OE standards and tests it for performance under high-stress operating conditions. The design emphasis on the pulley, clutch, hub, bearing, and wobble plate supports durability and consistent A/C system operation.
