TSI Supercool Synthetic U/V Leak Detection Dye, 1 oz, 1 Application

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.

Sadly, it revealed more leaks than expected! Excellent for finding leaks.

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.

This is a requirement for any reputable mechanic. It saves time and time is money. Glows bright and is worth keeping in the shop.

This stuff is fantastic! I didn’t even need the uv light it just popped. Great stuff.

Everything arrived as advertised. I haven't used it yet but looks to be perfect! I will post pictures after I use it.

The media could not be loaded. I bought a bottle and was going to add some to my radiator, but figured I'd try the blacklight on it first, and it didn't glow. Thought I had a bad batch, but did a little digging, and found out that it'll only glow after it's mixed with water or coolant. And it glow's quite well. Wish I knew that earlier, but I know it now :)

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.
