    Brandon, I've thought about soldering the lines onto the core and may still go that route. It seems a little ghetto but cant be any worse than my putty fix.

    Jimmy, I've just been running green **** in it, is dexcool the orange stuff that is supposed to be safe for any vehicle?

    dexcool is the orange **** you're supposed to run in gm vehicles.

    I am not sure when they started the dexcool deal. But I do know if you mix them your coolent turns black and gunks up everything.

    So you would have to flush the crap outta it to change.

    there are no more color designations. there is green stuff that is aluminum safe now. i doubt the truck in question requires dexcool. why do you even have a heater core?

    Good article. According to it if my truck came with Dexcool and I put green **** in it, I'm prety much ****ed. It says in that case just keep using green coolant cause it is prety much impossible to flush all the old coolant out of the system and even the slightest bit of green will contaminate the Dexcool.

    IIRC when I got my truck the coolant in it looked like muddy water so it was probably already contaminated. Anything that could contain coolant besides the engine block has been replaced since I've had the truck. I dont even know what kind of coolant it came with, I'll check my haynes manual when I get home.

    I always ran Dexcool, but apparently I didn't flush it enough and it corroded through the aluminum...

    can you sweat aluminum to copper? i've never tried. acid core solder may work although i usually use it for refrigerant lines.

    i think I will get my neighbor the AC guy to solder it up for me. You can flush the system with that Prestone Borax junk. I have used it a few times, works pretty good.
