Q: How to properly replace the condenser in Hyundai Santa Fe's air conditioning system?
A: To properly replace the condenser in your vehicle's air conditioning system, follow these steps: Have the refrigerant discharged by an air conditioning technician. Remove the Radiator supports, pulling the radiator upward and rearward to access the condenser. Disconnect the inlet and outlet fittings, promptly capping open fittings to prevent contamination. Remove mounting fasteners, then push the radiator back and the condenser rearward for removal. Install the condenser, brackets, and bolts, ensuring proper placement of rubber cushions on mounting points. Reconnect refrigerant lines using new O-rings where necessary. Reinstall remaining parts in reverse order. Finally, have the system evacuated, charged, and leak tested by the technician who discharged it.
