Will this bolt straight into my Suburban without any welding or fabrication?

Yes. This condenser uses factory mounting points — no drilling, welding, or brackets needed. Line up with the original attachment locations and secure.

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

Yes. Always flush the AC lines and receiver/drier before installing a new condenser to remove debris and moisture that can damage the new unit.

What about the refrigerant charge — does it come pre-filled?

No. This is a dry condenser assembly. You'll need to evacuate, pull a vacuum, and recharge your system with the correct refrigerant type and quantity per your vehicle's specifications.
