however, buy some black RTV when you split the heater box apart you need to reseal the box, if you do not reseal the box you will blow hot and cold air all over the passenger.

Just did it on my '90
Easy fix, it might differ slightly because mine is a little older, but they're pretty similar so here are the instructions for mine. First off get a new heater core, rockauto.com had the cheapest one for my vehicle. There are three nuts on bolts that come through the firewall that are 7/16th's in size, one is under the battery cradle. Take those off, easiest if you take the battery cradle off to see it, as well as a plug that goes to the blower fan. Disconnect the coolant lines that go to the heater core, you're going to want to drain some of the coolant out of the radiator before doing this to help reduce a mess (you don't need to drain all of it). Next disconnect the cables to the vents and pull out the heater unit from under the dash. Once that is out, take the screws off the back of the unit to reach the heater core, replace and re-install, easy! I did this in about an hour. Good luck!

How to replace heater core on a 94wrangler
My sons 94 Wrangler is smoking on the inside through the heater/defrost vents, slight puddle of anti freeze inside and out. I am assuming its the heater core.
Can someone give the breakdown on how to replace the heater core?
