    Default Oil Cooler Lines

    Folks,
    My GMC K 3500 needs oil cooler lines. (leaking) Who makes the very, very best lines that will not, ever, leak? Thoughts?

    I replaced mine with lines from Autozone, I have read that GM lines are best, I'd rather pay less and change more often.

    X2 ... GM lines are the best. Unless you can see that your hard lines are cracked or broken, then they are probably leaking from the O rings. Easy fix if that's all it is.

    I have a 2009 Silverado and they look like they are leaking where the steel and rubber meet which I heard was pretty common, the lines are wet but not dripping on ground are they easy to change?
