BeerBurner,
I went to a junkyard to get another radiator for my '95 Civic as it had cracked and was leaking. The junkyard had no used radiators but kept new replacement (aftermarket) radiators on-hand (these must apparently fail at a rather high rate). The price, as my memory serves me, as about $100... installation was simple and the replacement unit has done well. Take a peek a the Hayne's manual for the '05 Civic - my guess it is straightforward. My wife has an '08 Civic and I have not looked at this setup.
