Add the correct UV dye, let it circulate, then scan with a UV light. Leaks glow brightly so you can see where the problem is coming from. **Q: What kinds of leaks can I check with LeakFinder?** A: LeakFinder offers simple options for A/C leaks, coolant leaks, and oil-based leaks. Depending on the dye selected, it can help check areas like hoses, fittings, radiators, engine oil systems, transmission fluid systems, and power steering systems. **Q: Is LeakFinder easy to use?** A: Yes. LeakFinder is designed to make leak detection simple: add dye, run the system, and scan for the glow. It is a practical choice for DIYers, vehicle owners, and small shops. **Q: Do I need a special light to see the dye?** A: Yes. LeakFinder UV dye needs a compatible UV or violet leak detection light to glow. Some kits include a light, while dye-only products may require a light to be purchased separately. **Q: How does LeakFinder help save time?** A: LeakFinder helps show the source of the leak instead of relying on guesswork. Once the dye glows, you can focus on the leaking area and decide what repair is needed. --- ## 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.jp/products/381898463-lf3008-automotive-engine-coolant-leak-detection-dye-for-radiators-hoses](https://www.desertcart.jp/products/381898463-lf3008-automotive-engine-coolant-leak-detection-dye-for-radiators-hoses) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-09*
