Q: How to remove and replace the air conditioning compressor in a Hyundai Santa Fe?A: To remove and replace the air conditioning compressor in a vehicle, it is recommended to have an automotive air conditioning technician discharge the refrigerant. Start by disconnecting the negative cable from the battery. Then, raise the vehicle and support it securely on jackstands. Remove the drivebelt from the compressor and disconnect the electrical connector. Next, disconnect the refrigerant lines and seal the ends to prevent contamination. Unbolt the compressor and lower it from the vehicle. If installing a new compressor, follow the provided directions for proper oil level. During installation, replace any O-rings with new ones made for the purpose and lubricate them with refrigerant oil. Finally, have the system evacuated, recharged, and leak tested by the shop that discharged the refrigerant.
