Autodevil AC Compressor for 2003-2006 Ford Expedition & Navigator 5.4L / 6PV Pulley, Clutch Installed

Autodevil AC Compressor 98557 is a direct-fit, belt-driven replacement compressor with clutch designed to restore reliable air conditioning performance for 2003–2006 Ford Expedition and Navigator V8 models.

If your Expedition or Navigator has weak airflow, inconsistent cooling, or a noisy compressor, replacing the worn unit with this Autodevil model gets your system back to factory-like operation. Engineered from aluminum alloy and pre-filled with the correct oil volume, this compressor matches the original dimensions and pulley specifications to simplify installation and reduce fitment issues.

Will this compressor fit my 2003–2006 Expedition or Navigator?

Yes—this Autodevil compressor is specified for 2003–2004 Expedition 4.6L V8 and 2003–2006 Expedition 5.4L V8, as well as 2003–2006 Navigator 5.4L V8. It’s built to replace a long list of OE part numbers so it’s compatible with many original configurations.

• Direct compatibility with OE numbers like 5W1Z19V703AA, 6511483, YCC168, and 98557.
• Precision-engineered to original dimensions to ensure correct mounting and hose alignment.
• Meets pulley spec of 6PV grooves for belt-driven systems in these models.

What are the key specifications and included components?

The unit is made from aluminum alloy for durability and heat dissipation, and it uses a vortex-type compression mechanism. The package arrives with the clutch installed and the compressor pre-filled with oil, so it’s nearly ready for installation.

• Material: aluminum alloy for reduced weight and corrosion resistance.
• Pulley: 6PV groove configuration, belt-driven fitment type.
• Comes with installed clutch and pre-filled oil (do not overfill).
• Compressor type: vortex; designed for quieter operation and efficient refrigerant flow.

How will this compressor affect cooling performance and energy use?

Replacing a failing compressor with this Autodevil unit restores proper refrigerant compression and circulation, improving cabin comfort and system reliability. The design aims to keep energy draw reasonable while maintaining steady airflow and quieter operation compared with worn compressors.

• Efficient compression improves steady cold-air output under normal driving loads.
• Aluminum construction helps dissipate heat for longer component life.
• Clutch included and balanced to reduce vibration and noise transfer to the cabin.

What should I check before buying and during installation?

Verify the vehicle year, engine size, and existing compressor part number before ordering to ensure fitment. During installation, follow standard A/C service procedures: evacuate and recover refrigerant with proper equipment, confirm belt and pulley alignment, and leak-test the system after charging to safe pressures.

• Confirm vehicle: 2003–2004 Expedition 4.6L or 2003–2006 Expedition/Navigator 5.4L V8.
• Use correct refrigerant and charge amounts per factory specifications after evacuation.
• Do not add additional oil beyond the pre-fill; overfilling may damage the compressor.

Who is this for: This Autodevil AC Compressor is intended for owners, mechanics, and restoration specialists working on 2003–2006 Ford Expedition and Navigator V8s who need a reliable, OE-dimension replacement with a clutch included. It’s a solid choice when the original compressor shows signs of failure—such as noise, clutch slippage, or weak cooling—and when you want a straightforward swap that aligns with factory fitment and pulley specifications.
