I have noticed a couple of drops of anti freeze on

Right above the water pump there's a 90 degree elbow that's made out of plastic that comes out of the intake and goes to a heater core hose. That's where mine was leaking. Get it replaced soon because it will get worse. I heard this is common on these 3.8L engine.

Find the water pump and feel around the bottom of where it is mounted to the engine. If you detect coolant there, then the water pump needs replacing. They have a weep hole built in and when the seal goes bad it will leak coolant. Of course inspect all hose connections top and bottom. Look for cracks and hard spots. If you cannot find the leak then take it to a trusted mechanic and have the cooling system pressure tested to find the leak.
