Fixed the leak and fixed my frustration il never use anything else again works 1st time
I was Absolutely Blown Away! LIQUI MOLY Radiator Stop Leak is a Miracle Worker! Like many, I've battled stubborn car radiator leaks, trying various "miracle" products that promised much but delivered little more than frustration. My expectations were, to say the least, tempered when I decided to give LIQUI MOLY Radiator Stop Leak (150 ml) a try. And wow, am I glad I did! This product is in a league of its own. From the very first application, it was clear I was dealing with something massively superior. Within minutes, the leak, which had been a persistent headache, was completely stopped. Not just slowed, not just a temporary patch – genuinely stopped, first time. I'm incredibly impressed. LIQUI MOLY has truly engineered a formula that performs exactly as advertised, saving me the cost and hassle of potentially expensive garage repairs. If you're struggling with a radiator leak and have been disappointed by other products, do yourself a favour and get this. It's an absolute game-changer and has earned its place as a permanent staple in my garage. Highly, highly recommend!

Worked well!
Had a pinhole leak on the radiator of my 2010 Volvo XC90 that only became apparent when I changed the water pump. I had thought of changing the rad out but due to needing to use the vehicle for a few jobs I decided to give this a go. It worked perfectly and stopped the leak after 5 minutes. I’d say the fix might outlast the car!

Fonctionne bien
Je n’y croyait pas mais ça a fonctionné. J’avais une micro fuite (passage du maxi au mini en environ 1000km). Et depuis 3 mois et 2 000km le niveau de liquide de refroidissement n’a pas bougé.

Valido per micro-perdite, ma è un rimedio temporaneo
Ho utilizzato questo sigillante Liqui Moly per risolvere una leggera trasudazione dal sistema di raffreddamento e devo dire che ha fatto egregiamente il suo lavoro, bloccando la perdita nel giro di pochi minuti. L'applicazione è semplicissima e il costo è davvero contenuto rispetto a un passaggio immediato in officina.Bisogna però essere realistici: questo prodotto è ideale per micro-fessure o giunti leggermente porosi, ma non può fare miracoli se ci sono fori evidenti o perdite importanti. Nel mio caso lo considero un'ottima soluzione d'emergenza, utile per tamponare il problema e continuare a usare l'auto in sicurezza in attesa di un intervento meccanico risolutivo e definitivo.

Eficaz, limpio y sin efectos secundarios
Tenía una pequeña fuga en el radiador y no quería cambiarlo aún porque el coche tenía otras averías y no sabía si me merecía la pena seguir invirtiendo en él. Probé este sellador de Liqui Moly con ciertas dudas, pero ha resultado ser todo un acierto. Apliqué un bote para unos 8 litros de refrigerante y desde entonces, ni rastro de fugas. Antes se notaba enseguida por el olor del refrigerante, muy característico, y porque bajaba el nivel. Desde que lo eché, ni huele ni pierde. Además, no ha generado ningún problema en el sistema de calefacción, cosa que a veces pasa con otros productos. Todo sigue funcionando con normalidad. Muy recomendable si buscas una solución rápida y eficaz sin complicaciones

One word to describe this "WORKED"
Had a leak somewhere on my 06 Volkswagen Beetle Convertible and could not find it for the world. I was putting in a liter a week of antifreeze and decided to buy this. I put it in, drove it for about an hour and the leak was gone and had no engine issues from using it!!! Great stuff!!!!!. Took a little long, 2 weeks, to get here but coming from overseas, I expected it to.
