Features & Benefits:
  • This compressor is prefilled with 3 oz. of OE-Specified oil and includes an additional 8 oz. bottle of oil
    • Refer to Four Seasons' Capacity Guide, vehicle's Underhood Decal or Service Manual for system oil requirements - add or drain oil accordingly, to ensure proper lubrication.
  • 100% vacuum and leak tested for long life and proper performance
  • Includes required o-rings / sealing washer for ease of installation
Service Tip: Once filled with oil, place or hold the new A/C Compressor with the front seal facing down for 1-3 minutes. This will help coat the seal with oil - if this seal is not lubricated before installation, refrigerant may leak.
Benefits of an A/C Compressor & Component Kit

Purchasing and replacing just the A/C Compressor is less expensive up-front, but may lead to more repairs and expenses down the road. A complete A/C Compressor & Component Kit provides added benefits:

  • Extend Service Life: Brand new components, free of contaminants help protect your new A/C Compressor from premature failure.
  • Fulfill Warranty Requirements: A/C Compressors returned under warranty must show proof of purchase of the A/C Orifice Tube (or A/C Expansion Valve) and A/C Receiver Drier / Accumulator.
  • Save Time & Money: Don't risk having to re-do the repair - do the job right the first time!
Which A/C Compressor Do I Need?

Certain vehicles came with multiple compressor styles. You can only replace your current compressor with the same style compressor. Locate the tag on the back or side of your existing compressor. Look for information like Manufacturer Name, Compressor Type / Style, and Model Number / Part Number.
