I haven't had a leak happen yet with it in the system but I expect it'll do what it should if and when the time comes... Ran it in a couple systems for a couple months and doesn't seem to have caused any problems. Review: Well sealed bottle in the box. Nice and bright blue under a UV light. Will be grabbing another bottle after repairs are completed to verify we got all of the leaks. Update 3/11/25 Ordered second bottle, yep, missing it's cap and the foil was punctured like other people complained about so I guess you have a 50/50 shot of getting something that's actually usable. ## Features - Designed to quickly pinpoint leaks in cooling systems that use DEX-COOL (orange) coolants - Special formula will not change the color of the coolant - Fluorescent dye assists with visual leak detection to eliminate guess work - Works in conjunction with the ACDelco Ultra Violet (UV) Leak Detection Lamp Kit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008I2VKNI | | Best Sellers Rank | #31,496 in Automotive ( See Top 100 in Automotive ) #28 in Automotive AC Leak Detection Tools | | Brand Name | ACDelco | | Color | Colorless | | Compatible Material | Metal | | Customer Reviews | 4.7 4.7 out of 5 stars (324) | | Included Components | Leak Detection Tracer Dye | | Item Form | Liquid | | Item Type Name | Leak Detection Tracer Dye | | Item Weight | 1 Ounces | | Manufacturer | ACDelco | | Manufacturer Part Number | 10-5046 | | Model Number | 1149328 | | Number of Items | 1 | | UPC | 707773856260 | ## Product Details - **Brand:** ACDelco - **Colour:** Colorless - **Compatible material:** Metal - **Item form:** Liquid - **Item weight:** 1 Ounces ## Images ![ACDelco 1149328 GM Original Equipment 10-5046 Dex-Cool Leak Detection Tracer Dye - 1 oz - Image 1](https://m.media-amazon.com/images/I/51OBSUCAbfL.jpg) ## Questions & Answers **Q: I tested this out by shining a uv black light in the bottle but it doesn’t glow. Am I missing something?** A: I think these have a shelf life and can lose their zing. I had a competitors sit in a dark cabinet for a couple of years and nothing under uv. I got a new bottle and it's bright like expected. Check your purchase to make sure it's still good before using. **Q: Can this product be used in a Duramax?** A: What's a Duramax? This is a fluorescent dye that you put in your car's radiator so that you can detect leak around the engine. It really doesn't matter what make of car it is **Q: What's the difference between this and 10-5057?** A: looks to be the same! Just make sure your coolent is Dex-cool **Q: Will this work for a 2003 vw golf tdi 1.9t coolant system?** A: It should work with any cars coolant system. It's intended to detect leaks, but you'll also need a UV (black light) to be able to see where the leak is ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on 15 January 2026* Seems to be genuine Delco dye.
