Coolant Sys.

I own a 2000 Ranger XLT, 3.0ltr 4x2, with the 4spd auto. I don't really want to spend 50+ bucks to flush the coolant system out if I don't have too. Is it hard to do with this model?...How would I go about doing so?...I didn't think it would be too hard, but with all the hidden valves and special clauses on these new vehicles, I just want to be sure. If you can post some instructions or a link or two, it would be greattttly appreciated.
