My '98 Civic DX (185K miles) is slowly losing coolant. It takes about a month for it to get low enough that the engine coolant temp starts to get above the "normal" range (a little less than half-way up). I don't see any signs of leaks on the engine. Within the last 3 months, I've installed a new radiator and two new coolant hoses.

If the water pump was leaking, I'd see it at the bottom of the driver's side of the engine, right?

Any ideas?

I have a couple scan tools, so I can read any PID to help diagnose the problem.

Yes, the leak would be around there.
Well... it could be a blown head gasket. That's kind of a big deal. You can diagnose it with a kit like this one:
