Review on 🔍 Certified AC Pro Car Air Conditioner Stop Leak Detector Kit: Glasses, UV Pen for O Ring and Hose Leak Detection - Professional Grade (438) by Mark Jefferson

These jars and lights along with a separately sold dye worked fantastic! I had a leak on my truck that I thought was from the water pump, but if you've ever tried to get a good look at the water pump area of a Chevrolet Silverado, it's next to impossible. After adding dye to the cooling system and looking at the water pump area with the goggles, I could easily see exactly where the leak was! Thanks, this saved me a ton of time and possibly money!
