Hello, this is not a how to about heater cores, but I just did mine on my 97 4WD 4 door. I will tell you that even tho its a minor pain to remove the whole dash, it makes life easier in the long run. I removed the dash, following some of the posts I have read here (this place is great,as are the people). I took my time and made sure I marked all the connectors so I dont miss one when I put it back together. The weather isnt cooperating with me today, so I am going to finish tomorrow. One thing I did do, was instead of trying to pry the hoses off, I took a sawzall and cut the tubes off of the core on the inside, then I pulled the hoses thru the opening. That gave me more than enough room to take off the hoses easily under the hood. It has gone very well so far. I do have pictures and if I can figure out how to get them on, I will. Ok, got it. the first pic is my car with the dash out. The second is the old core, see the bad spot on the right, the third is the new core. Thanks
