I definately, was, but now it seems I have a small high-pressure coolant leak. I do not know where it's coming from. I suspected it's coming from the thermostat housing, but I didn't see, smell or feel anything coming out of there.
#1 - Is there something out there I can put in to the coolant that will help give a telltale?
#2 - I've heard of putting grated ginger into the coolant to plug up the leak. Any opinions on that?

The car uses green coolant.
