    My 91 4.3 needed a new radiator during the warranty period, think it was 40 K or so. Now have 225 K on it, and it still runs great. I also replaced the radiator about 70 K ago...this one from PepBoys for about $150, we installed. Always have kept it clean, and flushed, but when I was living in LA area, I had to have it reliable.
    Still love my truck, still running strong.

    When you changed your Radiator Shelby 12 did you install a heavy duty one.I have had the radiator flushed ,acid bathed and rodded out and it still overheats with a load and air-on.Was there a recall on the radiator

    Hi folks,

    This is a great discussion, and for the benefit of our community as a whole, I would like for it to be taking place somewhere where it can be available to all of our members as time goes on.

    A problem with very narrowly named topics is that they tend to deal with the topic title's problem only, and then fade away.

    The software here can only retain a certain number of topics in our archives, so that a discussion that fades after having a relatively few number of posts is a large candidate for deletion rather than archival.

    With all of that said, I'm going to take the liberty of copying all of these posts to the newly formed Chevy S10 Problem (Topic #1752).

    A topic with that sort of name can live a long time around these parts.

    So please, follow that highlighted link and let's continue this great discussion over there. You'll find all of these posts there waiting for you. :-)
