So as nearly as I can tell there's a small crack in one of the pipes on my Rampage's heater core. I've got a new one coming in, but figure I should get started on getting the old one out. Is there anything resembling an easy way to do this? Does someone have step-by-step instructions on doing it? I've got an OOOOOLD Haynes-type book on the car (from a company that may no longer exist?) but its instructions are far from useful. The car is technically an AC car (though nothing under the hood is still there) for reference. Thanks!
(and since I know it's likely to get brought up, simply bypassing it isn't a viable solution on anything but the very short term- I'll likely be driving the Rampage through the winter so will NEED head in it)
