Review on 🔍 Spectronics Corp/Tracer TP39000601 1oz Engine Coolant Dye - Set of 6 by Charles Alvey

I had a mysterious coolant leak on my car that was using a liter of antifreeze per week. I smelled antifreeze but couldn't detect any leaks. I added a bottle of this dye and used one of the UV flashlights I bought from Revain. I found the leak in seconds (intake manifold to plug the leak - the antifreeze would evaporate before reaching the bottom of the engine). It definitely works. I recommend doing this at night or in a very dark place as the leak will appear as a bright green/yellow light.
