how do you replace the heater core 97 wrangler?

I have a 97 jeep wrangler and i have coolant leaking all over the carpet. i was told iit is my heater core. I have the dash all the way off and can't figure how to get the black box out which contains the heater core. if any one has any tips, or like a place on the net that has directions please ur help would be greatly appreciated.

www.alldata.com Check out the DYI section for consumers. Their is a fee and its good for a year of use. Or I recomend the FSM.
As far as an other sites..??

Here is the quick run down:
If you have A/C it must have the freon removed.
Disconnect the heater hoses
Remove the a/c heater plenum mounting bolts on the engine side of the firewall.
Disconnect all electrical connectors and vacume hoses from the plenum assembly
double check and remove any connections or wires.
Drop the plenum assemblyy down and out.
Split the assembly and remove and replace the heater core. clean the inside as required. and reassemble.
re-Install in reverse order

Now this was a real quick how to. You will need a manual, either check the above from alldata, or check a auto parts store for one as last resort.

This may seem really obvious, but make sure you just don't have a leak in a hose before you pull out your heater core.
