Instructions
1. Disconnect the battery
Disconnect the negative battery cable to disable the power supply to the A/C system.
2. Recover the refrigerant
Use a refrigerant recovery/recycling machine to recover the existing refrigerant from the A/C system. This is a critical step as it prevents the release of harmful refrigerants into the atmosphere.
3. Remove the A/C condenser
Remove the condenser by disconnecting the electrical connections and unscrewing the mounting bolts.
4. Remove the A/C accumulator/receiver
Disconnect the accumulator/receiver and remove the mounting bolts.
5. Remove the A/C compressor
Disconnect the compressor and remove the mounting bolts.
6. Remove the A/C expansion valve
Disconnect the expansion valve and remove the mounting bolts.
7. Remove the A/C evaporator
Disconnect the evaporator and remove the mounting bolts.
8. Replace the A/C components
Install the new A/C components in reverse order. Before installing the new components, make sure to inspect the connections and seals for leaks.
9. Evacuate the A/C system
Use a vacuum pump to evacuate the air and moisture from the A/C system. Evacuation is crucial as it eliminates any impurities that may affect the performance of the system.
10. Recharge the A/C system
Connect the manifold gauge set to the system and charge it with the recommended amount of refrigerant. Always follow the manufacturer's specifications while recharging the A/C.
11. Test the A/C system
Once the system is recharged, test its operation by turning on the A/C and checking for proper cooling and airflow.
Note: It is recommended to have the A/C system serviced by a trained professional, especially while recovering refrigerant and handling its components. Some areas may have regulations regarding the disposal of refrigerants, so make sure to follow the local guidelines.
