Quick delivery..great product has fixed the problem..thankyou

Mostly solved leak

I've used Radweld on several vehicles over the years, and it's successfully fixed small coolant leaks every time I've needed it. While it's not a substitute for a proper repair when major components are damaged, it's been an excellent solution for minor leaks and has saved me a lot of time and expense. It's very simple to use—just follow the instructions and add it to the cooling system. On previous vehicles, I've seen leaks stop shortly after application, and the repairs have lasted far longer than I expected. I've always kept a bottle on hand because it's one of those products you hope you won't need, but it's great to have when a coolant leak appears unexpectedly. Based on my experience across multiple vehicles, it's a product that genuinely works and has earned a permanent place in my garage.

Worked a treat, I had went through about 5 litres of anti freeze,, poured this in no more leaks.

Using the Radwell helped for a few weeks but the water loss recently started again, albeit at a lower level of loss than originally experienced. The car will be serviced in January so hopefully we shall find the reason for the water loss.

Great emergency repair product! Easy to use and works quickly to help seal small leaks in the cooling system and radiator. A simple pour-in solution that provides a reliable temporary fix and peace of mind. Very handy to keep in the garage.

My mk8 ford fiesta had a slight leak from the coolant radiator. I read other reviews that said it was good so I decided to try it. As long as you follow the instuctions, it should fix small leaks in the coolant system. It worked for me. It's great value & i would recommend.

Ho saputo di questo prodotto per molti anni. Usato una volta nel nostro veicolo molto tempo fa. Funziona davvero e avete solo bisogno di fare una volta. Problema risolto. Non ha esitato a comprare di nuovo quando un problema simile si è verificato su un altro veicolo.

Stopped coolant leak from cross-over pipe in Subaru Boxer engine.

Tras leer infinidad de opiniones sobre otros productos parecidos y buscar información en foros me decidí a probar este por sus buenas críticas en USA donde la mayoría son vehículos automáticos de gran cilindrada los cuales exigen más presión en circuitos etc, el mio es un Saab 93 Turbo automático 175cv Gasolina y perdía todo el líquido del bote expansor en una semana, tras varios intentos de pedir cita sin éxito en un taller para repararlo lo antes posible decidí probar temporalmente con este producto, lo primero que se aprecia es que no tiene particulas flotando como los otros productos que he visto al estilo del nural70, el caso es que a los 20 minutos de vaciarlo en el bote expansor y dar una vuelta con el desapareció la fuga, ni rastro de ella, no se cual será el secreto ya que como digo no tiene esas partículas como otros productos que supuestamente van tapando las fugas del circuito, solo quiero usarlo como solución temporal hasta que lleguen los recambios para mí vehículo pero probablemente lo dejé más tiempo así para testar su efectividad lo mas tiempo posible,conclusión: Es una solución temporal estupendas si no te fías de los típicos productos que tienen partículas dentro, dentro de un mes comentaré de nuevo. Edito un año después a dia 4/02/2018 Después de un año mi vehiculo a vuelto a perder liquido refrigerante ya que no lo reparé puesto que no perdia ni una gota y por poco mas de 5 euros me parece magnifico que aguante todo un año, he vuelto a comprarlo y lo usaré de nuevo haber si vuelve a funcionar y si no tocará pasar por el taller.

Ich habe bei meinem Subaru Impreza auf ca 500km immer deutlichen Kühlmittel Verlust im Ausgleichsbehälter feststellen können. Ich habe dann erstmal nach Lecks und ähnlichem geschaut aber nichts gefunden. Dann wurde mir von einem Bekannten dieses Produkt empfohlen. Ich habe nach dem einfüllen der halben Flasche gleich eine Fahrt von 60km gemacht und den Kühlwasserverlust weiter beobachtet. Ich musste dann nochmal nach ca 500km ein bisschen normales Wasser nachfüllen und danach war nach den nächsten 5000km kein Verlust mehr Sichtbar.

It did absolutely nothing, I was so excited as my problem is only a small issues and i though this would work. as i said it did nothing. At least it did not make things worse. As i did some research and read some horror story on how it ruined some engine. Just wish it would have worked for me
