## Description

ACDelco Coolant System Fluorescent Tracer Dye is a fluorescent leak detection dye for traditional coolant systems. This fluorescent tracer dye quickly pinpoints the exact location of coolant fluid leaks. It is a safe and easy method that helps eliminate guess work, save labor, and speed up service. ACDelco Coolant System Fluorescent Tracer Dye may also be used to isolate power steering system leaks. ACDelco Coolant System Fluorescent Tracer Dye can be used with DEX-COOL coolants, but it may change the color of the coolants.

Review: Good quality product great value for the money - This stuff is strong! Had a very slow leak for years, mounted to basically vapor, never leaked enough to get on the floor, but the smell was annoying, and I did have to top off the coolant every few months. This Audi has a very complicated cooling system, it even splits into two parts to send coolant separately to the supercharger. After putting the bottle in and running the car, I was able to find the leak in seconds. That said, this stuff does not flush out of the system. You’re going to have die in your coolant pretty much forever unless you completely vacuum flushed the entire system. In my case, I drained out What I could from the radiator and the hoses while I was doing the repair and although my OEM fluid is pink, everything was bright fluorescent, yellow green from the dye, as it should be. But even after flushing as much as I could, it still was fluorescent green, with about 80% new purple OEM fluid it’s still pretty much green, lol not a big deal. And by the way, I dropped about a gallon of coolant with the dye in it on my concrete driveway and it rinsed right off no problem.
Review: Works great - Shows leaks perfectly. Shows bright green with UV light. I suggest using half of what's recommend.

## 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.

### ⭐⭐⭐⭐⭐ Worth every penny!
*by J***N on March 12, 2025*

I've had a coolant smell coming from the front of my Jeep since I bought it 3 years ago and I couldn't find the leak to save my life. I've only added a quart of coolant the entire time, so I knew it wasn't that bad and I watch the level like a hawk. I decided to try this stuff just for fun and wow! I found it in daylight as soon as the engine warmed up without a uv light! It was the last place I would have guessed because the seal on the radiator cap looked fine. Once the system pressurized, it pushed past the seal and turned into steam. So THAT'S why I never saw any leaks! I was ready to replace the radiator, but all it needed was a $10 radiator cap! BUT WHATEVER YOU DO, DON'T SPILL IT! This stuff is SUPER concentrated! I spilled the smallest amount while pouring it in and tried to wash it off with the hose. Now my driveway looks like a nuclear waste spill. This is all from spilling about 1/4 ounce. And no, it's not coolant on the ground. Highly recommended!
