The antifreeze already has a fluorescent dye in it. That's why it's
that bizarre day-glo green color. Any handheld UV light will make
leaks show up.

The problem, though, is that as soon as water gets into the oil, it boils
right off. Same happens to the glycol. And when it boils, it will take
a lot of the dye with it. You have to have a pretty major leak into the
oil for any to show up.

I urge the original poster just not to worry about it. Keep all fluids
topped up. Either the problem will get worse or it won't.
