Had a coolant leak I couldn't find at all. Put this in the coolant reservoir and drove the truck for a couple hours and found the leak glowing coming from under the water pump. Good stuff

You'll easily be able to find the leak with this.

THIS STUFF literally GLOWS in the DARK-if you have a LEAK you will find it- even in the engine oil.

Found multiple leaks in the coolant system including a devastating leak in the radiator. Working to replace things now to get the car back on the road! Budget friendly; you don’t need the whole bottle. I used about a 1/4 of it.

Immediately found the leak in my system. Only thing I dislike is the instructions say to use the whole bottle. This stuff is potent. Only use the whole bottle if your doing a 5 liter engine. You should use a quarter or half on a small compact car. Weirdly, it goes in red and is meant for dexcool. But after it's mixed in the whole system turns iridescent green.

Took about a minute to detect leak with uv light, highly recommend!

Works great, used 1/4 of ounce and was WAY too much, could have used about 1/8th and been more than enough. Will buy again if needed.

Used this for a coolant leak, after putting in the de-gas bottle, it was " jumping " out at me as it ran off the water pump.
