Coolant Flush Video

I'm a visual learner when it comes to mechanical crap. God did not bless me with the ability he gave my dad to just look at something mechanical and have it drop its panties for him. YouTube is woefully vacant in that area.

Are there any good step-by-step videos on Coolant flushes for the Roadster? I'd like ot do as much maintenance myself as I can safely learn.
