Product Details

Nissens part number 891777 is an A/C compressor engineered for vehicles using R1234YF refrigerant. The compressor uses a 6SBU14 design, a 6-groove serpentine pulley, and a 12-volt clutch setup to support stable belt-driven operation. Nissens focuses on the pulley, clutch, hub, bearing, and wobble plate to help maintain pumping efficiency while limiting noise and vibration. This part cross-references Chrysler (e.g., 68347809AA) for the same application.

Common Symptoms This Part Can Address

• Weak or inconsistent cabin cooling
• Compressor noise, squeal, or vibration from the front accessory drive
• A/C system pressure loss tied to compressor wear
• Clutch engagement problems in the air conditioning system
• Reduced cooling performance in R1234YF-equipped vehicles

Installation Notes and Tips

Before installation, verify refrigerant type, pulley alignment, connector style, and belt routing against the vehicle’s original compressor. Replace the O-rings during service, evacuate and recharge the system with the correct R1234YF refrigerant, and confirm proper oil level before startup. For Chrysler 68347809AA applications, confirm the compressor mounting and electrical connection match the original unit. Fits are not listed in the supplied data, so vehicle-specific compatibility should be confirmed by VIN and original part number.
