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

I drive a Ford Crown Victoria and there was a small coolant leak in the car that I couldn't find. I added this to the tank and rode it one day, and the next night I went out with a UV light to find the obvious leak. There was a microcrack in the intake manifold, which expanded so far when hot that coolant could drain out. This dye is bright. The dye is also visible in daylight without using a UV lamp. Great things will continue to be used in the future
