I noticed the leak on the flexible lines near the radiator. There are two, approx 12", rubber lines as part of the main metal lines. It is at the metal/rubber connection that the lines appear to be leaking. It is not enough to be noticeable on the garage floor but the rubber lines are covered with fluid. No metal lines are damaged as far as I have determined. I will perform the reverse-accelerator-don't get run over- test to be certain.
A local tire replacement store suggested that I would need to replace all the lines but it appears I could locate the leak and simply cut in a replacement line, or at least find the previous connection point and replace from there. I like the idea of having all metal lines with the quick connect fittings.
Thanks for the procedure. I'll update when I have completed the work.
