INSTALLATION

CAUTION: 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 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 seal is required anytime a refrigerant line is disconnected. Failure to replace the rubber O-ring seals may result in a refrigerant system leak.




1. If removed, install the A/C pressure transducer (8) onto A/C condenser (1) using a new O-ring seal. Tighten the sensor to 10 Nm (88 in. lbs.).
2. If removed, install the A/C receiver/drier (9) onto the A/C condenser.
3. Carefully install the A/C condenser into the engine compartment and engage the condenser mounting brackets to the radiator (2). Make sure the brackets are fully engaged.
4. Position the top of the radiator forward and engage the retaining tabs that secure the radiator to the radiator support. Make sure the retaining tabs are fully engaged.
5. On diesel engine equipped models, connect the hoses to the charge air cooler and install the two front air seals to the front of the charge air cooler.
6. Connect the wire harness connector (7) to the A/C pressure transducer.
7. Remove the tape or plug from the opened refrigerant line fittings and condenser ports.
8. Lubricate new rubber O-ring seals (6) with clean refrigerant oil and install them 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.
9. Connect the A/C liquid line (5) to the A/C condenser.
10. Install the nut (4) that secures the A/C liquid line to the A/C condenser. Tighten the nut to 6 Nm (53 in. lbs.).
11. Connect the A/C discharge line (3) to the A/C condenser.
12. Install the nut that secures the A/C discharge line to the A/C condenser. Tighten the nut to 6 Nm (53 in. lbs.).
13. Install the A/C condenser fan assembly.
14. Install the grille.
15. Connect the transmission cooler lines to the passenger side of the radiator.
16. Install the engine cooling fan and fan shroud.
17. Install the engine cooling system reservoir.
18. Connect the upper radiator hose to the radiator.
19. Reconnect the negative battery cable.
20. Refill the engine cooling system.
21. Evacuate the refrigerant system.
22. 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. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
23. Charge the refrigerant system.
24. Install the air cleaner housing.
