Review on 💡 Tracer Products TP34000601 UV Fluorescent Leak Detection Dye Set: Enhance Leak Detection with this Complete Set of 6 Dyes by Mike Devine

This stuff works great! I had a differential leak but couldn't pinpoint exactly where the leak was coming from. I figured it was probably a transmission seal, but I didn't want to take the back apart until I was sure it was the problem. I added Tracer Products leak detection fluid to the diff, topped up the diff fluid, then cleaned the diff case thoroughly and drove the car for about a week. Then I just crawled under a truck in a dark garage with a UV flashlight and Tracer Products Leak Detection Fluid lit up the leak like crazy! This showed me EXACTLY where the leak was coming from! The gear seal was fine - leaking through the third element seal - a much easier and less expensive repair than the gear seal. So this product saved me time and money - good stuff!
