    I read your heater core replacement article and decided to just jump in and do mine which I thought just started leaking in the last couple of weeks. WRONG!!! It apparently has been leaking very slowly for quite some time, by the looks of the floor. At any rate, your article was a great help. As it turns out, if you know what you are looking for, the job wasn't to bad, just a waste of a good Saturday morning. The only thing I did contrary to your article was not droping the fender well. I found that with a socket, a universal joint, two extensions, and four hands I could reach the bolt. As luck would have it, both bottom bolts broke off. The clean-up and repair of the floor, padding, and carpet is a lot worse than the heater repair.

    Thanks for the good article.

    Derf00, Hey can you give me a clearer picture of just what length your driver, and the bends for the univeral joints were. I already drilled the access hole in my fender a couple of years ago, but it pissed me off so bad, I am still looking for an answer. I often wonder whether the Mr Goodwrench had a special tool, made just for it, as I can't see dropping the fender well just to do it.

    If you ain't hurt, you ain't playin' hard enough.

    Glad it helped.
    General......GM put the box in before the front of the truck was on and didn't care what a pain it was 20 years down the line when it fails. Could be worse. I got a Supra also and I hear I have to remove the steering colum interior A piller garnish and the trim peice at the top of the windsheild inside hold those in. Then I can pull the complete dash to get to the core if it fails. I hear the dealer charges like $400 in labor to do the job.

    I used a 10" and 4" 1/2 drive extensions, the universal and socket. The key element was the piece of electrical tape I wraped around the universal to keep it from flopping around when we were trying to stab the bolt. Which ever route you take, the job just plain sucks.
