Help diagnose leak
Loose drain on an 99-02. Leaky radiator. Leaky expansion tank. Loose tank cap. Leaky hose to the thermostat housing. Leaky hose from thermostat to the heater core hard pipe below alternator.
Get a flashlight, crawl under her and start looking.
If you really want to get fancy there is a uv dye you can put in the system to find leaks with a black light or uv light. I generally use this for ac system leaks but I've had some stubborn coolant leaks over the years that it could have helped narrow down

It could just be that your system is slightly overfilled and expansion has pushed some coolant out of the overflow.
Or maybe there's a hairline crank in your reservoir.
Feel around the various coolant locations when the engine is cool to see if you can isolate any damp spots.
