I posted here the other day about a bunch of anti-freeze smelling steam seeping up through my dash and console while driving.

I popped the hood and noticed that there was alot of rust and water on this side of my radiator and could hear it hissing..

I haven't looked when my truck heats up completely, but could this steam be coming from a bad radiator?

What are my options with radiator, do I buy new one, get it repaired or how does this work from a save me money perspective? Thanks
