91 Sonoma Pickup leaking Coolant?

my 91 GMC Sonoma pickup 2.8 V6 has a coolant leak. Woke up this morning and went to leave and seen a leak going down my drive. I Put water in the Radiator to get it to level and i checked it after 10 miles and it now needs more. I Looked under there and it has a slow drip from off the Oil Pan. Mabey leaking somewhere off the motor and leaking down to the oil pan? Im confused. The water pump and radiator has been replaced 6k ago. I Just got the oil change yestarday too. Thanks!! Also i noticed that when you run the heat you can smell coolant but it did this 6k miles ago too! Thanks
