When I did mine I just pulled the clips off the two lines going into the firewall, put a small tarp over the back side of my motor so the coolant didn't settle on my motor and cut the line with a utility knife from as far back as I could reach to close to the tip of the pipes from the heater core and they came off really easily.. When I put the new one in I just trimmed the hoses so the ends were straight and I had plenty of hose still. Hope this helps some

 

Oh and a little FYI, make sure ur emergency brake is fully engaged and you block ur wheels because when I dropped the steering column it pulled my shifter down out of gear, just a heads up

 

Oooooo, now THERE is a useful bit of information. Thank You.

 

never fails.. i always end up breaking something! alright tell me what i should do for this.... sorry all pictures are sideways..
it comes out of the side of thisnot the 90degree one the straight one)

and goes up to:

 

Just use a short piece of vacuum line to splice it back together. You can throw a little glue in there too if ya like. (just don't plug the hole.)

 

Junkyard scavenging time. Easy peasy.

 

alright, guess ill wait till dad gets home to go get some line..
and is there any trick to getting these damn AC lines apart? ive been tuggin and pullin tryin to gettem off.. thinkin thats the last thing i lack to getting the big box out.. and its stressin me out

 

You need the tool to separate the lines. Available at any parts store. Are you looking in a manual? or just winging it?

 

going off of youtube vids and stuff on here.. ive seen people say you don't need to take off the AC lines.. if i did that, id have to release all the freon right? and how much would that be?
i have the box out far enough for the heater core to come out of the top. taking a break before i go back out to pull it out.. it does just pop out the top right?

 

Read the link I provided, the only way you can replace the heater core without disconnecting the AC is to use the swivel joint heater core. And get a damn Haynes and download the FREE service manuals for the FAQ/DIY section.
