3.7L/4.7L/5.7L Engines

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 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:

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.

  2. Install the two bolts (5 and 9) that secure the A/C condenser (2) to the right side of the radiator (4). Tighten the bolts to 2.2 N.m (20 in. lbs.).
  3. Remove the plugs or tape from the opened jumper line fittings and condenser ports.
  4. Lubricate new O-ring seals with clean refrigerant oil and install them and new gaskets onto the jumper line fittings. Use only the specified O-ring seals 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 discharge and liquid jumper lines to the A/C condenser and install the bolts (3 and 8). Tighten the bolts to 23 N.m (17 ft. lbs.).
  6. Install the bolt (7) that secures the condenser jumper line tapping block (6) to the radiator. Tighten the bolt securely.
  7. If equipped, remove the plugs from the transmission cooler ports and using new O-ring seals, install the automatic transmission cooler jumper lines (10) to the transmission cooler tapping block and install the bolt (1). Tighten the bolt securely.

    NOTE:

    4.7L model shown in illustration. 3.7L and 5.7L models similar.

  8. Install the radiator and A/C condenser as an assembly. Refer to RADIATOR, Engine Cooling , Installation .
  9. If equipped, connect the automatic transmission cooler lines to the transmission cooler jumper lines. Refer to TUBES AND HOSES, Transmission Oil Cooler , Standard Procedure .
  10. Remove the plugs or tape from the opened refrigerant line fittings and condenser jumper line ports.
  11. Lubricate new O-ring seals with clean refrigerant oil and install them and new gaskets onto the refrigerant line fittings. Use only the specified O-ring seals 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.
  12. Connect the A/C discharge line (3) and A/C liquid line (4) to the condenser jumper line tapping block (1) and install the nuts (2). Tighten the nuts to 23 N.m (17 ft. lbs.).
  13. Reconnect the negative battery cable.
  14. Refill the engine cooling system. Refer to Standard Procedure .
  15. If equipped, check and adjust the automatic transmission fluid level. Refer to FLUID and FILTER , Standard Procedure and FLUID and FILTER , Standard Procedure .
  16. Evacuate the refrigerant system. Refer to Plumbing , Standard Procedure .
  17. 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.
  18. Charge the refrigerant system. Refer to Plumbing , Standard Procedure .
