Do I need to evacuate the AC system before swapping this in?

Yes. Your AC system must be properly evacuated by a certified technician before condenser removal and recharged after installation. This is a legal requirement and necessary for system function.

Will this mount at the factory attachment points without modification?

Yes, this condenser is designed for factory mounting locations. No drilling or frame modification required — use existing bolt holes and brackets.

Is this a complete assembly or will I need a core from my old condenser?

This is a complete, ready-to-install assembly. No core exchange needed, and no core charge applies.
