Before ordering, verify vehicle compatibility by comparing part numbers and images or using your vehicle fitment tool.

What should I expect during installation and maintenance?

PHOBOOS builds this unit to OE-style dimensions so it installs as a direct bolt-on for compatible trucks. Because it ships prefilled and includes the clutch, labor focuses on swapping the unit, evacuating and charging the A/C system, and checking belt alignment and electrical connectors.

• OE-matched bolt pattern and electrical connector for straightforward replacement
• Prefilled oil reduces initial service steps; final refrigerant evacuation/charge still required
• Inspect hoses, dryer/accumulator, and expansion device to avoid contaminating the new compressor
• Follow professional A/C service procedures for vacuum, leak test, and correct refrigerant charge
