Ford Lincoln Mercury Fitment and OE Number Check

Confirm These Vehicle Applications

• Selected Ford F-150, F-150 Heritage, F-250 Super Duty, F-350, Excursion, Crown Victoria, and Mustang applications

• Selected Mercury Grand Marquis and Cougar applications
• Engine applications may vary by vehicle, including 4.6L, 5.4L, 6.0L, and 6.8L setups listed for this compressor family.

Compare OE / Interchange References

• Compare your original compressor label and catalog data with these references: CO101290C; CO-101290C; 57129; 58129; 9U2Z19V703ARM; AU2Z19V703AD; E3AZ19V703AA; HU2Z19703X.
• Match the compressor body, mounting ears, clutch face, pulley alignment, electrical connector, and refrigerant port layout before ordering.
• Do not choose an air conditioning compressor by vehicle name alone because engine, production date, or previous repair history may affect fitment.

Ford Lincoln Mercury A/C Symptoms to Diagnose Before Replacement

Symptoms That May Involve the Compressor

• Warm air from the vents, weak cooling at idle, intermittent cooling, or an A/C clutch that does not engage may be related to the compressor.
• Compressor noise, pulley bearing noise, belt squeal, oil trace near the compressor, metal debris, or compressor seizure can point to compressor or clutch damage.

Other A/C System Causes to Check First

• Low refrigerant, refrigerant leaks, condenser airflow, cooling fan operation, relay, fuse, wiring, or pressure switch faults can cause similar symptoms.
• Expansion valve, orifice tube, receiver drier, accumulator, blend door, HVAC control, belt, or tensioner issues should be inspected before replacing the car AC compressor.

Before Ordering This BDFHYK A/C Compressor

Match the Original Compressor and Clutch Area

• Use the OE / interchange number as a reference, then visually compare the original vehicle AC compressor before purchase.
• Service the A/C system using proper refrigerant recovery, evacuation, oil, and recharge procedures.
• If the previous compressor failed internally, inspect the condenser, lines, drier or accumulator, and expansion device for contamination before installing a new AC compressor.
