I use this in my shop to conduct initial diagnostics. I also use this https://amzn.to/3WHrgXl and highly recommend both products. Save big money diagnosing your leaks.

Worked just like I hoped and I found more then 1 leak. Definitely a huge help in diagnosis and saves me tons of money in diagnosis fees!

I’ve been chasing this micro leak for over a month. It’s been very difficult to find because it wouldn’t really show signs until after about 20 miles of driving. But it would release the pressure from the overflow cap and spray coolant everywhere and I couldn’t pin point the leak. I FOUND IT IN 3 MINUTES USING THIS PRODUCT. I HAD A BLACK LIGHT WHICH WAS USED IN THE 1st PICTURE. 2nd photo is without the black light. It’s actually visible without it but I suggest grabbing one off Amazon. Love the results.

Does exactly what it should, easy to identify a coolant even before breaking out the UV light. But it is REALLY concentrated. I used this on a BMW with blue coolant and after 8 radiator flushes the coolant still has a tint from the dye. You might try using 1/2 the bottle first…it’s probably more than enough.

This little bottle is incredible. The bright neon color is so bright you won't need a uv light to see. Perfect for detecting any leak.

Leaking antifreeze and couldn't tell where. Put about 1.5 Oz. And let it run for about 3 .minutes. Using the black light it was easy to find. Great stuff!

This works great. It mixed into the coolant via the radiator cap with no trouble. I found a leak at the bottom radiator hose which would have been troublesome to fond without the dye. It glows so brightly that you will see any and all areas that have even a tiny seeping leak. This stuff makes the coolant glow like a beacon!

This definitely helped me pinpoint the leak. I highly recommend it. Just pour it in and it lights up when illuminated by a uv flashlight.

Great to track leaks in my cooling system, but the dye will stain clothing and skin, so wear old clothes and gloves.

Worked very well. Makes it very easy to track where coolant is leaking to with a UV light. Lights up very bright when UV Light is shown on it
