Detailed Description

Nissens 891755 is an A/C compressor engineered for OE-level fit and function in R134A air conditioning systems. The compressor uses a VS16E design with a 6-groove serpentine pulley, 12-volt clutch operation, and a 2-pin connector. Nissens focuses on the compressor’s critical moving parts, including the pulley, clutch, hub, bearing, and wobble plate, to support smooth pumping action, low noise, and reduced vibration. This part number, 891755, is listed for 2012-2018 Kia Optima and 2012-2014 Hyundai Sonata applications.

This part cross-references UAC CO29159C and Global Parts Distributors LLC 6512961 for the same application.

What It Helps Address

• Weak or inconsistent cabin cooling output.
• Noisy compressor operation from worn internal components.
• Vibration caused by compressor wear or pulley issues.
• Loss of A/C performance in R134A systems.
• Service replacement needs for OE-style compressor fitment.

Installation Notes and Tips

Verify refrigerant type, oil specification, connector style, and pulley configuration before installation. This compressor is filled with shipping oil only and must be drained and refilled to the correct specification during service. Confirm the system is clean and properly evacuated before returning the A/C system to operation.

Quality Assurance

Nissens manufactures compressors to OE standards and tests them for performance under demanding operating conditions. The design emphasis on the pulley, clutch, hub, bearing, and wobble plate supports durability, pumping efficiency, and quieter operation.
