    I have antifreeze dripping out under the glovebox on the firewall. Is my heater core going out or could it be a loose or broken hose inside the plastic box?

    Most likely the core is shot. Still a pain to find out though /forums/images/graemlins/frown.gif

    Is there anyway to stop it for the summer and wait until fall to fix it?

    unplug your heater hoses in the engine compartment that go into the heater core and run the ends together with a piece of pipe until you can get it fixed. That will let it bypass the heater core altogether /forums/images/graemlins/thumb.gif

    I replaced my heater core and it only took me an hour, I was figuring it to be a much larger job than it was. /forums/images/graemlins/thumb.gif

    I agree, anyone that thinks a heater core is that bad is either a whiner or has never done it.

    I'd do a heater core a million times over the other crap I always end up doing.

    I must have been a complete retard then, it took me at least 4 hours but then again I went in and fixed all of my venting system. Plus I had never done it before. At least it's not a messy job. I just bypassed my heater through the summer last year. It's not that bad to do I guess /forums/images/graemlins/whistling.gif Go here for some tips

    I have never done it, so I had no idea what it all intails but thanks for the info. It sound fairly easy so I'll probably just do it this weekend. Thanks for all your help. /forums/images/graemlins/thumb.gif /forums/images/graemlins/waytogo.gif
