A 1976 dodge w200 that I picked up some time ago and had got it running and stopped working on it. Instead of putting it in storage, got it going to run under its own power, pretty reliable, getting it back on the road again.
My '82 W150/225 might have the same problem. Do you know of any cheaper and greener corrosion inhibitors that can be used for summer coolant when it might leak out any time? I have distilled water with about 1 tablespoon of light oil and a bit of graphite powder and some stop leak in it now. How might I improve on that formula? but still cheap?
