How to Replace the Compressor in a KIA Sedona

Save

According to costhelper.com, the average labor cost for replacing an air conditioning compressor is between $200 and $400. While some aspects of compressor replacement cannot be done at home, doing most of the labor on your own will save you almost all of the labor costs. Expect to pay between $50 and $100 to discharge and recharge the air conditioning refrigerant in your Kia Sedona.

Things You'll Need

  • Pliers
  • Socket wrench set
  • Torque wrench
  • Replacement o-rings
  • Replacement compressor
  • Bring your Sedona to an EPA-certified refrigerant technician to discharge the air conditioning refrigerant. Amendments to the Clean Air Act only allow certified professionals to discharge and replenish R-134A refrigerant.

  • Gather materials and park your vehicle on level ground. Disconnect the negative battery cable with the pliers.

  • Locate the compressor and pulley on the left side of the engine bay. Remove the belt from the pulley and loosen the bolts from the pulley to remove it.

  • Disconnect the suction line and discharge line from the compressor. Plug or cap the lines to prevent contaminants from entering the system.

  • Unplug the air conditioning clutch connection from the compressor.

  • Use the socket wrench to remove the four bolts from the compressor. The bolts mounting the Sedona compressor are different lengths. Note the location of each bolt. Remove the old o-rings from the compressor fitting.

  • Install the new o-ring on the new compressor if it is not already equipped. Mount the compressor using the torque wrench, placing the bolts in the same order as they were. Tighten the bolts to between 14 and 21 foot-pounds.

  • Connect the air conditioning clutch connector and the two hoses back to the compressor. Tighten the nuts as much as you can without stripping them.

  • Mount the pulley to the compressor and replace the drive belt.

  • Bring the Sedona back to a certified refrigerant technician to re-charge the air conditioning refrigerant.

Tips & Warnings

  • Consider purchasing a used or re-manufactured compressor to save on the purchase cost. If you do, make sure it comes with some type of guarantee or warranty.
