Well, I looked for this information all over the internet today and finally broke down and bought a Chilton's manual. It says to locate the heater fan assembly just below the dash on the passenger side and there will be a section that just houses the fan itself. That is what you must remove. You will unplug the fan (2 connectors at the top of the assembly), then remove screws that surround the fan assembly, disconnect the rod from the heat mixture lever (near kick panel on right), and remove the assembly. Then you need to open the hood and remove the 2 heater hoses (there will be leakage if you don't drain the antifreeze first). Go back in the cab and pull the heater core free.
