Will this bolt directly onto my 4Runner without modifications?

Yes. This condenser mounts at the factory attachment points — no drilling or fabrication needed. Match your existing refrigerant line connections before ordering to confirm fit.

Does this come with new o-rings or seals for the refrigerant lines?

The condenser assembly itself does not include replacement o-rings or line seals. Pick up new seals when you service your refrigerant system — this prevents leaks at connection points.

Can I install this myself, or do I need a technician?

Removal and bolt-on installation are straightforward for anyone comfortable with hand tools. Refrigerant evacuation and recharge require EPA certification — have a shop handle the AC service portion.
