Get a 365nm light. *by D***S on 15 January 2026* The only Radiator specific dye that i could find. All others are for oil and are not compatible with coolant. It works amazing and it glows really bright fluorescent yellow under 365nm uv light form a cheap torch. The ammpount was more than enough for a very large LR4 V8 with dual AC system. ### ⭐⭐⭐⭐⭐ Review *by C***N on 26 March 2025* Sooooo very concentrated and BRIGHT. This product helped me diagnose a gremlin in my coolant system. 5/5 stars, great product. ### ⭐⭐⭐⭐⭐ Review *by T***I on 15 January 2026* This stuff worked great, one ounce was more than enough. For those who said the product didn’t fluoresce in the bottle, I believe it needs to mix with the coolant/water to really light up. Remember this is to be used with a black light/UV light to see the leak. While it was bright enough to see some areas with no artificial UV light, it is ideally used with a UV light. Super bright for me, showed the leak clearly and was in an area that I never would have thought of or found without the leak detector. ## Frequently Bought Together - TSI Supercool Synthetic U/V Leak Detection Dye, 1 oz, 1 Application - REALHUNLEE Air Conditioner UV Dye Leak Detector, Pro Auto Oil AC UV Dye Leak Test Detection Tool Kit 68 LED A/C UV Flashlight Detector with Protective Glasses - InterDynamics Certified Auto Pro Oil and Fuel System UV Dye Leak Detection for Cars & Trucks & More, 1 Oz, 374CS, Universal --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/542686674-synthetic-u-v-leak-detection-dye-1-oz-1-application](https://www.desertcart.kr/products/542686674-synthetic-u-v-leak-detection-dye-1-oz-1-application) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-09*
