ACDelco 1148963 GM OEM 10-5045 Multi-Purpose Fluorescent Leak Detection Dye - 1 oz Review

Easy to use product that is added to the steering fluid before pouring it into the reservoir Super bright Easy to find a leak I had my suspicions as to where the leak was, this just confirmed it

The product is very good. But don't be stupid like me and add it with the engine running. It spattered all over the engine bay. Luckily for me you can't see it.

Fantastic work! I used it to find a gear leak (housing crack!). At the concentration I used, it was very noticeable even in ultraviolet sunlight. The gearbox held about 4 liters. I would suggest using 1 full 8 liter bottle.

The only problem is that I have never used it, there is no idea how much it can be used. Half? whole bottle? It would be nice if x ounces of motor oil stood per y ounces. In any case. You can use too much, but it definitely makes finding leaks easier.

I watched a few videos on how to use it and was told you need to use a lot for it to show up well. My results were just the opposite. It's pretty strong and makes it easy to see leaks/cracks. Glows bright orange under black light. I'll definitely grab a bottle of this in case it runs out.

Pretty cool product! I just wanted to test it out to make sure, so check out the attached video if you're interested. I tested the paint in a small bottle with a UV flashlight to see leaks as clearly as possible (it shows a fluorescent orange color so you can actually see it). Leaks are accurately detected! I'm a fan. :)

Works better than expected. The sunlight was enough to find this fountain, but the color saved a lot of time. 0.5 ounce, half bottle, placed in the power steering reservoir and started the car. In just a few minutes all the yellow paint was under my pressure hose. I think I use the other half of the bottle to find oil leaks.

I had a stubborn power steering leak and this black light method found the leak in no time. It was on the main wave! Wipe up the spilled liquid, refill, work for a while, look at the black light and voila, there's a leak. Expensive for 1 ounce. but I only used half as the power steering reservoir is quite small. An added bonus for me is that it's now easy to check the level in the pump with the black light!
