Review on ACDelco 1149328 GM Original Equipment: Dex-Cool Leak Detection Tracer Dye - 1 oz by Viterbo Dashora

I used this on a truck I just bought with low coolant. I filled up the tank with antifreeze and a bottle of leak detector just to get positive emotions. I am pleased to report that the bottle glows beautifully under a black light and no leaks have been found. I like the fact that I can use a special black light to quickly see all my visible bottled liquids in the dark.
