To install:


WARNING
Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.


NOTE
When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system.


NOTE
If only the A/C condenser is being replaced, add 1 fluid ounce (30 milliliters) of refrigerant oil to the refrigerant system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.


NOTE
Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.


NOTE
Be certain that each of the radiator and condenser air seals are installed in their proper locations. These air seals are required for the A/C and engine cooling systems to perform as designed.

  1. Carefully position the A/C condenser onto the radiator.
  2.  
  3. Install the four bolts that secure the A/C condenser to the radiator. Tighten the bolts to 44 inch lbs. (5 Nm).
  4.  
  5. Connect the receiver/drier inlet tube to the A/C condenser.
  6.  
  7. Tighten the screw that secures the A/C receiver/drier to the radiator and fan shroud. Tighten the screw to 44 inch lbs. (5 Nm).
  8.  
  9. Connect the A/C discharge line to the A/C condenser.
