Review on 🔴 Highly Concentrated Red Tracer Dye - 1 Gallon (128 fl oz) by Raymond Gray

Intermittent leak problem! Sometimes a very small amount of antifreeze dripped onto the concrete. But we couldn't figure out where it's coming from. So while we were parked and the engine warmed up to operating temperature, I added 16 ounces of this matrix to the cooling system. After starting the engine for about 15 minutes and using the UV lamp. I found that it was dripping/coming at the very top, in the left hand corner under the top radiator shroud. Went took a kind of stop leak. Which solved the problem. This stuff works
