Unless the leak is serious, I would give it several heat-up & cool-down cycles, just riding, and tracking the volume of the losses. It is possible that the seals will soften and seal as they should, in a bit. I'm no expert, but your problem seems fairly rare, here. I would not rush into repair mode, if I could simply top off the coolant a few times, and only then start to worry.

P.S. Life is too short, and health is too valuable, to ride on cheap parade-duty tires.
