And do i have to rev it or just idle it?** A: Since I used the fluorescent dye to detect leaks from the power-steering system I had to drive my car around for approx 15 mins to actually see where it was leaking from. At idle I couldn't see any leaks. After the drive the leak was pretty obvious and the UV light picked it up right away. **Q: are glasses included?** A: Yes. They are an amber/yellow color **Q: does it come with dye for a/c** A: Yes it comes with a/c dye **Q: Can the kit be used to identify transmission leaks?** A: transmission leak should b readily identifiable by the red tint already in the fluid to b sure either water blast or at least hose off under hood all oils and then get on fairly clean surface to see if red oil shows up keep in mind u could have more than one leak and some people will put trans fluid in power steering complicating matters ## Frequently Bought Together - Mastercool 53351 Professional UV Leak Detection Kit – 12V High-Intensity Light – Detects A/C, Coolant, Fuel, Oil, ATF Leaks – Includes Universal Dyes, Glasses, R134a & R12 Compatible - Tracer Products TP34000601 UV Fluorescent Leak Detection Dye - Set of 6 - UV Fluid Leak Detection Dye, 8 Oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/3605817-53351-professional-uv-leak-detection-kit-12v-high-intensity-light](https://www.desertcart.tn/products/3605817-53351-professional-uv-leak-detection-kit-12v-high-intensity-light) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-17*
