ERRECOM Brilliant Coolant – 100 ml, Car Radiator Coolant Cooling System UV Leak Detector Dye

There's loads of liquid here, you only use a bit. With a cheap ultraviolet torch from Amazon I found my 1 leak and glad to say there was only that 1. This stuff does exactly what you expect it too. The leak was in a hard to spot area where no daylight can reach so with the ultraviolet torch this stuff stood out well, nice bright reflection. It will last for a long time this bottle as there's so much in it. I nearly poured the bottle in, good job I read the instructions. Incredible value for money tbh, I've let somebody else use it on their car too with similarly excellent results. The only thing negative was the bottle leaked in transit so I had to take it out of the packaging in the sink with the tap on but only a little bit had come for m under the lid and the packaging had taken a beating too.

Ideal to find the leak in coolant system, dose to the recommended amount and using a uv torch it glows where the leak is. Enough to do multiple systems, advice go around the coolant hoses and engine area with uv light before dosing, then after adding the fluid as items glow even when no leak present so you will see exactly where a new glowing area leak actually is

ERRECOM Brilliant Coolant does exactly what it promises. The dye mixes easily with the coolant, shows up clearly under UV light, and makes even small leaks quick to identify. A small 100 ml bottle goes a long way and can save hours of guesswork when diagnosing cooling system issues. Reliable, simple, and very effective.

Overall this is very good. It definitely helped locate the leak I had. It would have got 5 stars but it can be a little tricky to see sometimes.

I’ve used this 4 times as directed after coolant issues in a couple of cars and 4 times I’ve been able to find and fix those problems. You do need a UV light to pair with it but no complaints if used as you should

Epic stuff. 10xx better than the cheaper stuff on amazon. Just need a decent UV light to go with it

Great product

Worked as it should. Supplied UV torch highlighted areas where the dye was.

Pour ma part ne fonctionne pas du tout. J'ai d'abord mis la dose recommandée, puis la totalité du flacon. J'ai testé plusieurs lampe UV, 0 réactions. J'ai finalement changé pour un produit concurrent, qui lui à fonctionné du premier coup !

Good

Produto difícil de encontrar pois é específico para o sistema de refrigeração do motor. Compatível com todos os anti-congelantes e pode permanecer no sistema mesmo que não exista qualquer fuga. Reage muito bem com uma lâmpada de luz UV. Se existir uma fuga externa é garantido que a encontra com este líquido. No meu caso encontrei uma micro fuga no topo do radiador. Muito recomendado. 100% Bom. A embalagem tem 2 tampas, 1 tampa é doseadora. No meu caso precisei apenas de 30ml para todo o sistema. Sobrou ainda muito líquido para utilizar no futuro. 👏👍
