Heater Core
My heater core in my 72 F250 began leaking a week ago when I used it for the first time in who knows how long it sat. Is there a well known process for removing them or is it pretty simple to figure out? Finally taking it out because the mornings are getting colder and I desperately need my defroster

See if you can find a diagram but it shouldn't be that bad. Might be a good time to replace some heater hoses, radiator hoses, thermostat, flush system and replace coolant while you're at it. I would use new clamps, btw.

To be honest I'd feel terrible putting stop leak in my rig, just my opinion.
And yeah I hear ya, though I have new coolant since I had the radiator rebuilt. Thinking I'll have the heater core rebuilt and new hoses. Thermostat works at the moment so I'll leave it be, I don't want to fix something that isn't broken yet. Thanks guys!

It drops out pretty easily. Undo heater hoses and remove nuts I dont remember how many there 7/16.Under dash unplug blower motor remove center heater ducts and the box should pull out. Its been a few years since I did mine probably forget some steps.

+2 Pretty easy to swap. I'd draw down the radiator a gallon or so, pull the to hoses at the fire wall, loosen I believe 3 nuts in same area, go inside pull defrost hoses, allow unit to drop to floor, pull the core, replace and reverse this action.
Core should be about a $20.00 item, +/-.

This is on my list of things to do. Though I have not done it yet, the manuals and a couple of posts on here make it seem very straightforward:
