What's Involved In Replacing A Radiator Core Support?

[Funkdoobiest]

Is it a bolt-on or is it spot welded?

Its welded. Generally you'll need to unbolt and remove the front bumper cover, grill, headlights, and partially unbolt the front and tops of the front fender, remove the rad and AC condenser, and a handful of wiring harnesses and sensors that plug into the rad support. Its pretty simple to drill out the welds and chisel the support out after that.
