I've have replaced coolant temp sensor and thermostat but now I've started noticing a small coolant leak under front of driver side. Any ideas on where it's coming from?

Welcome to the forum from Virginia. The drip may be from up top but is dripping from the lowest point. Hop under and shine a light to see if you can trace it.
