Detailed Description

Nissens 891629 is an A/C compressor designed for select Nissan Altima vehicles from 2013 through 2018. The compressor’s critical components, including the pulley, clutch, hub, bearing, and wobble plate, are engineered to support stable pumping performance while helping control noise and vibration. This makes it a practical replacement when restoring cabin cooling on a Nissan Altima with an OE-style HVAC setup. The part number 891629 also cross-references UAC CO29074C for the same application.

This compressor uses R134A refrigerant, PAG 46 oil, a 6-groove serpentine pulley, and a 2-pin electrical connector. It is supplied oil filled and includes the clutch and O-rings. Because the fitment note specifies shipping oil only, drain and refill the unit with the correct oil charge before installation on the 2013-2018 Nissan Altima.

Common Problems This Part Can Address

• Weak or inconsistent cabin cooling
• Compressor noise, vibration, or rough operation
• Loss of refrigerant pumping efficiency
• Clutch engagement issues in the A/C system
• HVAC performance decline on a Nissan Altima

Installation Notes and Tips

Verify refrigerant type, oil type, pulley configuration, and connector style before installation. For 2013-2018 Nissan Altima applications, drain the shipping oil and refill the compressor with the correct PAG 46 oil amount specified for the vehicle system. Replace the included O-rings during service and inspect the rest of the A/C system for contamination, leaks, or restricted flow before charging.
