Do I need to recharge the system after installation?

Yes. Your AC system will need to be evacuated and recharged by a technician with proper refrigerant recovery equipment. The condenser alone is a passive component — the charge itself is handled separately.

Will I need new o-rings or seals?

Best practice is to replace o-rings at connection points during install to prevent leaks. Pick up a new set rated for your vehicle's AC system — your tech can advise on size and type when you bring it in.

What tools do I need to swap this out?

Expect to use basic hand tools — wrenches and sockets for fasteners. You'll also need a refrigerant recovery machine to safely drain the old system before removal. This is not a DIY-only task if refrigerant handling is involved.
