## Description

TSI Supercool 16532 Radiator Dye - 1-Ounce - Single Application is a Synthetic U/V Leak Detection Dye that is engineered to quickly find cooling system leaks. It is detectable with any U/V light. It is conveniently designed for easy measuring, use 1-Ounce per vehicle.

Review: Works well. - Works great. I would rather not use it because is is colorful enough even without UV that I think of it as messy, and drain and flush after finding and fixing leaks, but maybe I add too much, or maybe I should just not worry about that and rinse everything when done. It is quite water soluble and rinses clean off. My son calls it "predator blood", looks the same. Definitely helps finding obscure leaks on messy engines. Be sure to put it in the radiator. If put into an overflow tank, especially a non pressurized type, it may require a few heat cycles to transfer enough to where it matters to be useful. Obviously, won't help with a head gasket leak to the combustion chamber, unless you look with a borescope, maybe after letting it sit pressurized a while. Head gasket leak to crankcase (oil contamination), you shouldn't need this stuff for. The milkshake is perfectly fine for that.
Review: Great results - This stuff worked great, one ounce was more than enough. For those who said the product didn’t fluoresce in the bottle, I believe it needs to mix with the coolant/water to really light up. Remember this is to be used with a black light/UV light to see the leak. While it was bright enough to see some areas with no artificial UV light, it is ideally used with a UV light. Super bright for me, showed the leak clearly and was in an area that I never would have thought of or found without the leak detector.

### ⭐⭐⭐⭐⭐ Works Well, Just Use Carefully
*by B***C on May 14, 2026*

This dye works perfectly for finding radiator leaks. It’s easy to use and does exactly what it’s supposed to. Just be careful not to spill it, because it can slightly stain bright aluminum if it sits for a while. A UV light is technically needed, but you can actually see it with the naked eye—just not very bright. Overall, a very effective leak detection dye.
