Having had a coolant leak for a year and not been able to find it because it was only a little leak, I needed to apply some tricks so bought a pressure tester, not conclusive. Bought the dye and UV torch, 20 mins after pouring the dye in the torch highlighted a possible leak on a temperature sensor on the lower rad hose. This is where I thought the leak was after using the pressure tester. A new O on the sensor cured the loss of fluid. Now bought another bottle of dye to put it in "stock" for when I need it next.

I've used this UV dye to detect coolant leak in my car and I need to say it works perfectly I found the coolant leak using the UV light which saves me a lot of money on paing someone else for the diagnostic great product at a great price

Used to look for radiator leak . Very simple just empty half the bottle into rad, top up , run engine then keep checking for luminous green leak with black-light torch, simple as that. WORKS GREAT.

You have to supply your own aaa batteries, but it works a treat. Could not find a cooling system leak. Tried all the tricks. Put this in to header tank, ran engine until it got warm and the thermostat opened. Hey presto a glowing puddle on the floor, looked up and you can see the leaking junction. Amazing.

Helped me to easily diagnose a leak from my water pump. The only negative is that the torch isn't very good quality and I had to force the batteries in as the compartment is too small
