Do I need to flush the AC system before installing this condenser?

Yes. Before installation, have your system flushed to remove old oil and debris. Debris can damage the new condenser and reduce cooling efficiency. This is a standard AC service step.

Will I need to recharge the refrigerant after swapping the condenser?

You'll need to recharge the system after installation. When you disconnect the old condenser, refrigerant escapes. Have a shop evacuate the system, install the new condenser, and refill with the correct refrigerant and oil capacity for your vehicle.

Does this come with all the O-rings and seals needed?

The condenser assembly includes mounting brackets. O-rings and inlet/outlet seals are not confirmed as included — check your vehicle's service manual for the exact seal kit required, or purchase separately to ensure proper fitment at connection points.
