Highly rated and trusted for professional and DIY automotive maintenance. ## Description ACDelco Coolant System Tracer Dye is a fluorescent leak detection dye that is specifically formulated to pinpoint leak sources in cooling systems that use DEX-COOL (orange) coolants. The use of ACDelco Coolant System Tracer Dye will not change the original appearance of the long life coolants. This tracer dye is used in conjunction with ACDelco Ultra Violet (UV) Leak Detection Lamp Kit. Review: Seems to be genuine Delco dye. 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 | #43,036 in Automotive ( See Top 100 in Automotive ) #36 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: Should I flush my engine oil before switching from conventional to synthetic oil or vice versa?** A: No, it is not necessary to flush your engine when switching between motor oils. Typically, conducting a routine oil change and replacing the conventional oil with a synthetic motor oil will not require any additional maintenance. **Q: Do I need a special oil filter for a synthetic oil?** A: No, synthetic motor oil does not require you use a special filter. Oil filters are used based on vehicle specifications. Refer to your vehicle Owner’s Manual for guidance on what type of oil filter to use. **Q: Is there a way to tell if my engine oil needs to be changed or is running low?** A: Yes, if equipped, your vehicle’s oil life monitoring system will inform you when your motor oil needs to be changed. Refer to your vehicle Owner’s Manual for more specific guidelines. **Q: Does my transmission fluid need to be changed as regularly as my oil?** A: No, typically, transmission fluid lasts much longer than most engine oils. Refer to your vehicle Owner’s Manual to identify how often and when your transmission fluid should be changed. Severe usage and regular usage descriptions are provided. **Q: Is there a difference between power steering fluid and transmission fluid?** A: Yes, there is a difference. There are many types of transmission fluid. GM Genuine Parts and ACDelco recommend referring to your vehicle Owner’s Manual for fluid recommendations for all vehicle systems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on 15 January 2026* Seems to be genuine Delco dye.
