Hey, Im about to do the heater core this weekend, so I'll appreciate it if someone answer by saturday, but anyways...who thinks I should just cut a hole in the firewall to get to the heater core, I have access to all the tools I'll need and can easily make a plate to cover up the hole. Or should I just go crazy and try to pull the dash and do it the normal way???? And if I take the dash apart would I need to cut any wires or are they long enough to pull the dash away enough to work? thanks for any info

Gee Pat, I don't know, that's kind of a personal choice thing. Sort of like should I get a vasetomy or have more children. The vasetomy is quick, easy, small scar, minimal headaches. More children is an invitation to long term committment, lots of frustation, great rewards, hereditary insanity. Would you really want some one like me making those choices for you??

Personally, I dont see any problem with going in thru the firewall, especially if you make a nice plate to cover the hole, and seal it well with RTV to keep the water out of the inside of the car. Hell, make a nice stainless plate and polish it... might even look cool. If you do it the right way by pulling the dash, you run the risk of forgetting to reconnect an electrical or vac connector, and risk ending up with new squeeks. When my heater core goes out (notice I didnt say if!!) I am seriously considering going in thru the firewall, especially since I have about 25 extra wires with about 5 more connectors routed to the dash for extra gauges, indicator lights, and switches. Just my opinion.

Anyone got any pics of where and how much you would cut in firewall?
I was just looking at this the other day and thinking if my core ever went I would do the cut method.

I had considered the through the firewall method when I was doing my 88 cougar, but with a 5.0 you don't have enough room. So I went ahead a pulled the dash. No biggy! About 3.5 hrs I was ready to go. So that is what I'm doing on my son's 86 TC. I was planning on doing it last saturday but he had something come up at school and didn't come home. Hopefully I'll get this done Sept 29th.
Also remember even when you get the firewall cut, you still have to cut the heater box also to get the heater core out.

Since your looking for opinions, I would much rather spend the time to do it right. Even though it's going to be frustrating, you can have the satifaction of doing it without cutting up your car. And while your in there, clean out all the debris that's collected over the past 15 or so years.
