I saw a wet spot under the truck previously but did not find anything leaking with a cursory look. I moved it here the other day and the spot I moved it from had a smaller wet spot under the same place. Today I crawled under it and felt for wetness The shiny spot was dirty wet gunk. I did not notice wetness when I did the body mount but I did not touch the spot that is now shiny either. Everything above it is dry, the rad, the window washer and the rad overflow. I'm tending toward a theory that I spilled coolant when I was doing those flushes and its somehow staying wet and slowly dripping even though we have had 95+ heat here for a couple weeks.
Intermittent rad leak without pressure? Any ideas for tracing this?
