ECCPP AC Compressor for Ford F-150 4.2L (1997–2006) FS10 Direct-Fit, Pre-Lubricated & Tested

ECCPP's AC compressor is a direct-fit FS10 replacement designed to restore reliable air conditioning performance for 1997–2006 Ford F-150 4.2L trucks and select 2004 F-150 Heritage 4.2L models.

This heavy-duty replacement compressor is engineered to meet OEM-style specifications and arrives pre-lubricated, pressure-tested, and ready to install with the included clutch. Built from sturdy aluminum components and tested for vibration and noise, it aims to deliver consistent cooling performance while matching the pulley and mounting dimensions found on many late-1990s and early-2000s Ford full-size pickups. Before installation, we recommend professional fitting to ensure correct line connections and system evacuation.

How does this compressor fit my F-150?

The unit is manufactured as an FS10-type compressor sized and grooved to match original equipment on 4.2L V6 Ford F-150 models from 1997 through 2006, and for the 2004 F-150 Heritage 4.2L. It uses a six-groove pulley and a 127 mm pulley diameter so belt alignment and rotation match factory expectations.

• Compatible years/models: 1997–2006 Ford F-150 4.2L; 2004 F-150 Heritage 4.2L

What performance and durability features does it offer?

The compressor housing is cast from durable aluminum for strength and heat dissipation. Each unit undergoes nitrogen pressure testing to verify leak-free operation and is factory-lubricated to protect internal components during initial startup.

• Aluminum construction for rigidity and thermal stability
• Noise-tested to remain under typical drivetrain sound levels (below 72 dB)
• Pre-filled with correct PAG46 oil volume (70 ml) — do not add excess oil
• Includes clutch assembly for simplified replacement

What should I know about installation and maintenance?

While the compressor ships pre-lubricated and pressure-tested, correct installation is essential to avoid damage and ensure long life. Professional AC technicians will evacuate the system, verify refrigerant type and charge, and confirm electrical and belt alignments.

• Includes compressor and clutch; re-uses factory lines if undamaged
• Factory oil installed — do not overfill; over-oiling can harm operation
