To the best of my knowledge, there are actually 3 versions of heater core used in the 2004-2007 Caravan (Caravan, Grand Caravan) and I believe the main difference is the location of the hose connections. While I did not take photos, the only steps I needed to do on mine were: Removed center dash cover (this is the section beneath the radio. 4 or 6 easily accessible Philips head screws) Drop the brake pedal down (very easy. Remember to remove the brake switch first) Remove the bolt on the steering column (basically splits the column into an upper and lower half. The top half stays in place and the lower half lays down (it is hinged). Remove the screws holding the hoses and heater core in place and slide the core out (I used some aluminum foil to catch antifreeze that dripped out while I put some plastic wrap over the hoses and hose connetions (plastic wrap held in place with rubber bands). Reverse the steps to reinstall. This video is pretty good, [https://www.youtube.com/watch?v=RLa-GlVfTt4|https://www.youtube.com/watch?v=RLa-GlVfTt4] Take your time & you’ll do fine!
