Can coolant leak from the thermostat?

Seems like there a little coolant dripping right above and to the right of my alternator. Is that where it could be leaking from?

It could be leaking from the thermostat, there is a gasket there that could fail...I guess.

There are also two coolant lines that run right over the alt (those .5" diameter pipes on the front of the engine).

How did the swap go?

Check the seal, if I recall right it's nothing more than a liquid Goop type seal anyway. Permatex to the rescue

The weep hole from the water pump is in that location. You probably have a water pump o-ring that has gotten old and hard enough to where it doesn't follow the expansion and contraction of the engine block, and it is leaking coolant.

Keep track of your coolant level. It's not serious until you have to add coolant every day. Eventually you will need to take care of it, but maybe not for a while.

Mine would only leak during startup when the engine was cold. Once the engine warmed up and the clearances got tighter around the o-ring it would stop leaking, so I didn't lose any coolant while driving around.
