It really works!!
My car started leaking water from the cooling system, it slowly got worse yet we couldn't work out where it was leaking. I was having to top up my coolant every 2-3 days. Even my local garage said it's going to have to get worse before we can see where it's leaking!! Decided to buy some of this as the reviews were good, poured it in the radiator, drove it around 5 miles, no more leaks!! This has been in my car around 3 or 4 months now and still not had to top up my water. Fantastic stuff, will 100% recommend this product as it's solved my water leak. Obviously for major leaks or split hoses etc this will not be suitable.

This works!
I had a really small leak from my coolant system, but enough that I had to top up coolant every other day. I used this and it's cured it amazingly. Really great stuff.

One of the best
I tried what i thought was the best on (K Seal) which didn't work. then i tried this stuff, miles better, worked a treat. If i need to stop a small leak now this is the stuff i would buy again.

Low cost temporary repair
Low cost 'temporary' repair of slight water leak. In the long term I purchased a new radiator for piece of mind.

Avevo una perdita al radiatore del riscaldamento abitacolo della mia Accent vecchia di 13 anni e con 180.000 km alimentazione benzina/gpl. La perdita era minima e non si notava diminuzione liquido nella vaschetta di espansione ma si sentiva odore di liquirizia bruciata (tipica del liquido antigelo scaldato) e un anomalo appannamento dei vetri dovuti ai vapori di paraflu. Ho utilizzato Wynns radiator stop leak seguendo le istruzioni ed ha funzionato alla grande. Ho percorso ad oggi 1000 km senza alcun problema ulteriore. Il prodotto è liquido e va utilizzato l'intero contenuto del flacone inserendolo a motore caldo (ma non caldissimo) direttamente nel radiatore (fare attenzione se troppo caldo il tappo all'apertura) o nella vaschetta di espansione (eventualmente aspirare con una siringona e un tubicino liquido raffreddamento prima, per fare spazio al volume del prodotto da inserire). Nel mio caso la soluzione è arrivata dopo aver percorso circa 20 km e da allora non ho avuto più problemi. Vedremo in futuro se la soluzione regge. Le istruzioni sul flacone sono in inglese ma sul sito del produttore è possibile scaricare la scheda tecnica del prodotto e tutte le istruzioni in italiano

Bonjour Je confirme ce que dit le premier commentaire Produit très efficace Il suffit de laisser tourner le moteur ou de rouler quelques km chauffage a fond, le produit va vite circuler dans tout le circuit et colmater les petites fuite J'avais une fuite depuis des années qui s'aggravait, je devais mettre régulièrement du liquide pour compenser cette fuite, je ne savais pas que ce type de produit serait aussi efficace sinon je l'aurais utilisé bien plus tot De plus son pris est contenu et cette marque est réputée Je recommande ce produit
