The only stupid question is the one you didn't ask...

Does it have factory a/c? If so, check the tech articles. There's one with step-by-step instructions for replacing the heater core.

If no factory a/c, then do a search. There have been step-by-step instructions posted in the past.

I did mine and it was very easy. The nuts that hold the housing are on the fire wall. Just remove the nuts, heater hoses and the heater cable and the whole housing comes right out.

remove the whole box and if I remember correctly it comes apart and the core is inside, sorry it's been a few years, not hard really.

Yeah, the core is on the inside. It will be obvious how the box comes apart once you get it out. I printed out the tech article and used it as a step-by-step guide when I did mine. Very helpful! You may have to loosen some of the bolts that hold the dash on to manuver the box out from underneath. Other than that, it's pretty simple.

Good luck.

Do you have factory a/c or not? It makes a big difference...

If a/c, follow steps in tech article...

If non a/c you need to remove the entire box in one piece. There are studs from the heat box that extend through the firewall and have nuts on the engine side. Remove the nuts, heater hoses, control cables and wiggle the entire box out from under the dash (helps to unbolt the bottom of the dash). Then once out, the box separates to get the core out. It's easy, just takes time.
