WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:

Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. Refer to OIL, Refrigerant , Standard Procedure . 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.

CAUTION:

The A/C condenser must be replaced if an internal failure of the A/C compressor has occurred. Failure to replace the A/C condenser can cause serious damage to the replacement A/C compressor. Refer to CONDENSER, A/C , Removal .

NOTE:

When replacing multiple A/C system components, see the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. Refer to OIL, Refrigerant , Standard Procedure .

NOTE:

If only the A/C condenser is being replaced, add 30 milliliters (1 fluid ounce) 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 disconnected. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.

NOTE:

A/C condenser for manual transmission model shown in illustration. shown in illustration with front fascia removed for clarity. Automatic transmission model similar.

  2. Position the A/C condenser into the engine compartment and install the four bolts (2, 7 and 10) that secure the A/C condenser to the charge air cooler. Tighten the bolts to 10.5 N.m (95 in. lbs.).
  3. Remove the tape or plugs from the opened refrigerant line fittings and condenser ports.
  4. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the refrigerant line fittings. Use only the specified O-rings as they are made of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
  5. Connect the A/C liquid line (5) and A/C discharge line (9) to the A/C condenser and install the bolts (6 and 8). Tighten the bolts to 23 N.m (17 ft. lbs.).
  6. If equipped, connect the automatic transmission cooler lines to the transmission fluid cooler fittings located at each end of the A/C condenser. Refer to TUBES AND HOSES, Transmission Oil Cooler , Standard Procedure .
  7. Install the grill.
  8. Evacuate the refrigerant system. Refer to Plumbing , Standard Procedure .
  9. If the A/C condenser is being replaced, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrigerant system. When replacing multiple A/C system components, see the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. Refer to OIL, Refrigerant , Standard Procedure . Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
  10. Charge the refrigerant system. Refer to Plumbing , Standard Procedure .
