5. Connect the A/C suction line (2) to the A/C compressor (3).  

6. Install the nut (1) that secures the A/C suction line to the A/C compressor. Tighten the nut to 12 N.m (105 

in. lbs.).  

7. Install the battery. Refer to INSTALLATION .  

8. Install the air inlet tube to the throttle body. Tighten the clamp securely.  

9. Reconnect the negative battery cable.  

10. Evacuate the refrigerant system. See REFRIGERANT SYSTEM EVACUATE.

12. Charge the refrigerant system. See REFRIGERANT SYSTEM CHARGE.  

3.7L ENGINE 

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C 

refrigerant system. See REFRIGERANT OIL LEVEL. 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. See REFRIGERANT OIL LEVEL.
