The compressor mounts using a tangent mount system with a 25.4 mm (1 inch) distance from the clutch to the mounting flange, ensuring proper fitment in compatible vehicles. Electrical connection is simplified with a Packard terminal and a coil clock position featuring a single wire lead. Both suction and discharge ports utilize O-ring seals, with two sealing washers (O-ring A number 24354) included to maintain system integrity.

Common Applications and Problem Resolution

• Replacement for failing or noisy A/C compressors in vehicles using R134a refrigerant
• Restores proper air conditioning cooling performance and system pressure
• Addresses clutch engagement issues by including a new clutch assembly
• Solves oil contamination or leakage problems with a new oil-filled compressor

Installation Notes and Tips

Ensure the vehicle’s A/C system is evacuated and properly flushed before installing the new compressor. Verify compatibility with the vehicle’s refrigerant and oil specifications, specifically R134a and Pag 100 oil. The included clutch assembly simplifies replacement, but mounting hardware is not included and must be sourced separately. Check pulley alignment and belt condition during installation to prevent premature wear. Use the Packard terminal for electrical connections and confirm coil voltage matches the vehicle’s system (12V). Properly install O-ring seals with the included sealing washers to avoid refrigerant leaks.
