How to charge the AC system on Dodge Durango ?

CAUTION

Refer to the applicable system precautions for this system before performing the following operation. Failure to follow the warnings and cautions could result in possible personal injury or death.

NOTE

Always refer to the A/C Underhood Specification Label for the refrigerant fill capacity of the vehicle being serviced.

After all refrigerant system leaks have been repaired and the refrigerant system has been evacuated, a refrigerant charge can be injected into the system. For the proper amount of the refrigerant charge, always refer to the A/C Underhood Specification Label located in the engine compartment. An R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J2210 must be used to charge the refrigerant system with R-134a refrigerant. See the operating instructions supplied by the equipment manufacturer for proper care and use of this equipment.

WARNING

A small amount of refrigerant oil is removed from the A/C system each time the refrigerant system is recovered and evacuated. Before charging the A/C system, you MUST replenish any oil lost during the recovery process. Refer the equipment manufacturer instructions for more information. Evacuate the refrigerant system.

1. A manifold gauge set and an R-134a refrigerant recovery/recycling/charging station that meets SAE standard J2210 should still be connected to the A/C refrigerant system.
2. Measure the proper amount of R-134a refrigerant and heat it to 125°F (52°C) with the charging station. See the operating instructions supplied by the equipment manufacturer for proper use of this equipment.
3. Open both the suction and discharge valves, then open the charge valve to allow the heated refrigerant to flow into the system.
4. When the transfer of refrigerant has stopped, close both the suction and discharge valves.
5. If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle and set the A/C-heater controls so that the A/C compressor is engaged and the blower motor is operating at its lowest speed setting. Run the engine at a steady high idle (about 1400 rpm). If the A/C compressor will not engage, test the compressor clutch control circuit and repair as required.
6. Open the suction valve to allow the remaining refrigerant to transfer to the refrigerant system.
   
   CAUTION

   Take care not to open the discharge (high pressure) valve at this time.
   
   
7. Close the suction valve and test the A/C system performance.
8. Disconnect the charging station and manifold gauge set from the refrigerant system service ports.
9. Install the caps onto the refrigerant system service ports.
10. Verify proper operation of the HVAC system.
