CO 4425C UAC SD7H15 Compressor Assembly

It’s a truck A/C compressor designed to keep the cab cooling system operating efficiently. This air conditioning compressor is built for 12-volt automotive AC compressor applications in many trucks. It’s commonly chosen as a replacement when an existing compressor fails or becomes noisy, leaks, or won’t build proper system pressure.

Match the part number and key specs to your current unit, including 6 grooves, 12V, and the 125 mm pulley diameter. Also verify discharge and suction port sizes (18 mm discharge and 21 mm suction) and the clocking position listed for the SD7H15 compressor assembly. Cross-references on the listing can help compare to other truck air conditioning parts numbers used by different brands.

It’s best practice to replace related wear items and address contamination so the new automotive AC compressor isn’t damaged. Many installs also include a receiver/drier or accumulator and a system flush, plus verifying correct refrigerant oil amount for the truck A/C compressor setup. Checking belt condition and ensuring proper electrical supply for the clutch helps prevent repeat failures.
