How does your oil look like? Is it milky or not? If milky, you have a bad head gasket.

If oil is not milky, you may have a failing water pump. Failing water pump will drip via its weep hole underneath the water pump itself. I have to run my vehicle for 10-15 minutes IDLE and shine a flashlight on the water pump and found out that it was slowly leaking on the water pump's weep hole.

Just make sure you have a good tight coolant reservoir/radiator cap (still working at the specific PSI).
