A/C Condenser - Installation
INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system Refrigerant Oil Capacity. 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 systemRefrigerant Oil Capacity.
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.
1. Position the A/C condenser (3) to the front of the radiator (1) and engage the two condenser mounting brackets (2) to the radiator.
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 Nm (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 Nm (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. 3.7L and 5.7L models similar.
8. Install the radiator and A/C condenser as an assembly Engine Cooling Radiator - Installation.
9. If equipped, connect the automatic transmission cooler lines to the transmission cooler jumper lines Service and Repair.
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 Nm (17 ft. lbs.).
13. Reconnect the negative battery cable.
14. Refill the engine cooling system Service and Repair.
15. If equipped, check and adjust the automatic transmission fluid level Service and Repair.
16. Evacuate the refrigerant system Refrigerant System Evacuate.
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, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system Refrigerant Oil Capacity. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
18. Charge the refrigerant system Service and Repair.
