Well, I can't say that I know a whole lot about the coolant line
layout of the 1.9, having never actually seen one in real life, but
I've seen enough pictures to hazard some wild-ass guesses. Since all
the coolant plumbing its pretty much up top of the engine, the water
is probably leaking above and running down along the seam between the
engine and tranny to drip off underneath. The most likely location for
any slow drip is at a hose connection somewhere. From the diagrams it
seems like the likely culprit would be around that big fitting on the
driver's side of the firewall where the two large hoses connect. If
you have an auto tranny I'd check the two hoses from the transmission
cooler also. Perhaps someone on the list with more hands-on experience
with the 1.9 can provide some better insight?
