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

Yes. Drain the old coolant completely, flush the system with distilled water, and refill with fresh coolant rated for your 500. Old coolant trapped in the block or hoses can corrode the new radiator core.

Will this bolt in without any fabrication?

Correct — it mounts at the factory points with no drilling or bracket work required. Hand tools and basic mechanical ability are all you need.
