Is this product safe to put in my cooling system to check for leaks

It’s a uv dye I just want to make sure it’s safe to use in the cooling system before I put it in. The main coolant hose was replaced and the thermostat along with the serpentine belt. The leak it still there! It’s. Not as prevalent as it use to be. That’s why I bought the dye. And this

I've used the coolant dye a few thousand miles ago and the oil dye. As long as you use the right one
I don't think it's an issue.

I had to buy an adapter for Audi Cap and got the loaner tool for the cooling system pressure tester from the local autozoene. Worked great
