Do I need to add refrigerant after installation?

Yes. Once your old condenser is removed and the new one installed, the system must be evacuated and recharged with the correct amount of refrigerant. This requires AC service equipment — take it to a shop if you don't have the tools.

Will this work with my factory AC lines?

The inlet and outlet ports are designed for OEM connection. Your existing factory refrigerant lines will bolt directly to this condenser without adaptation.

What tools do I need to swap this out?

Basic hand tools — wrench set, socket set, and screwdrivers. You'll also need to discharge the refrigerant from your old system beforehand, which a shop can do if you prefer.
