  6. Remove the A/C compressor line nut from the condenser and position the A/C compressor line aside.
  7. Remove the condenser from the vehicle.
  8. Remove and discard the O-ring seals and seal washer.

Installation Procedure

  1. If replacing the condenser, add refrigerant oil to the condenser. Refer to Refrigerant System Capacities for system capacity information.
  2. Install the condenser to the vehicle.
  3. Install a new seal washer onto the A/C compressor hose. Refer to Sealing Washer Replacement .
  4. Install new O-ring seals onto the evaporator tube. Refer to O-Ring Replacement .
  5. Install the radiator. Refer to Radiator Replacement .

  6. Object Number: 1643649  Size: SH

  11. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    Important: Use a 20mm wrench or pliers to hold the A/C condenser block fitting, this will prevent the A/C line from twisting while torquing the A/C line nut.
