## Overview

## 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.

## 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
