Thanks for the comments. I'll take another look at the water pump, hoses, and heater core. But I'm telling you I've looked hard and can't see any sign of a water leak. It's losing a good gallon of water for every hour/ 2 hours of driving, so I'm thinking I would be able to notice the leak! The theory that it's only leaking at operating temp. while running might be the winner, though, because I have noticed a slight antifreeze smell when driving. I'll let you know what I discover.
