A Leaky Mystery

99 Rodeo, 4-banger, stick. Here are the clues:
Top radiator hose got split and was replaced. Next day, coolant pouring from hose at the firewall. Couldn't get to it so mechanic replaced, along with the plastic water tunnel (I think he broke, but that's another case). Since then, car runs great, no overheating or noticeable leaks. But...every morning, there's about a half-cup, maybe less, of coolant/water on the driveway. Can't see where it's coming from and it doesn't happen during daily driving. What/where should I be looking for this leak?
Many thanks.

Waterpump, bottom of radiator, there are a ton of tiny hoses on the 3.2L, so I'm guessing there's gotta be a fair share of little ones on the 4-cylinder Rodeo as well
