Detailed Description

Nissens 891541 is an A/C compressor replacement built to OE standards for vehicles that require an SD7H15 compressor with R134A refrigerant. Its critical components, including the pulley, clutch, hub, bearing, and wobble plate, are designed to support smooth operation, efficient pumping, and reduced vibration under high-load conditions. This makes it a practical choice for A/C compressor replacement on Honda Civic applications and other vehicles using the same compressor specification.

This part cross-references UAC CO4471C for the same application. The Nissens 891541 part number is also useful when matching service parts by compressor type, pulley configuration, and electrical connection details.

What It Helps Fix

• Weak or inconsistent cabin cooling
• Compressor noise from worn internal components
• Clutch engagement problems
• Refrigerant circulation loss in an R134A system
• Vibration or belt-drive issues related to compressor wear

Installation Notes and Tips

Verify compressor type, pulley groove count, connector pin count, and refrigerant specification before installation. Confirm the system uses PAG 100 oil and replace the O-rings during service using the included seals. Evacuate and recharge the system according to the vehicle service procedure after installation of Nissens 891541.
