you have to remove the heating unit and fan from under the dash. this is done by unbolting it from the fire wall. Be sure to bypass the heating core if you need to drive your Jeep around. Then open it up a nd pop out the core. once you replace the heating core seal up the heating unit with silcon sealant. then be sure to make it fit well when you put it back in or water can come down into the the unit from the intake. also if it isn't in tight air will blow through the cracke from the engine compartment

It is never easy to replace a heater core. Replace it is easy, but getting access to it is never easy. But your Jeep Wrangler is one of the easier ones to replace. Just remove enough of the dash parts to gain access to the core. Be careful and remember where and how everything goes back together. Photos taken during the process with digital camera might help you remember.
