I have a 2012 Toyota Prius type v they're generation known to have head gasket issues over time. Well my time had come last winter Winter of 2024 and I was deciding whether to put new engine in it though I did not have the money and I called a repair shop in town called engine and transmission exchange and told him I dilemma. Well to my surprise The gentleman behind a counter felt my problem and told me try this he had a guy who delivered parts who had a old Chevy van that had the same head gasket issue. He gave it a shot because one of his mechanics told me to try it what's the worst that could happen. By God it worked that man has been driving that same vehicle for 5 years now so I gave it a shot. It's a year later I've had no head gasket issues whatsoever no overheating no loss of fluids since that time I put it in. Heck of a lot cheaper than the engine. A $23 bill is a heck of a lot cheaper than a 5 to $6,000 engine replacement.

Très bon produit. Très efficace.

Iba a llevar mi coche al desguace y gracias a este producto funciona perfectamente, ideal para roturas de junta de culata leves

das Zeug hat in nullkommanix das Thermostat abgedichtet. Immerhin... Ich glaube, dass so Zeug unter optimalen Bedingungen funktionieren kann, ich habe es sicherheitshalber bei einem alten Auto angewendet, bei dem der Wechsel der ZKD nicht wirtschaftlich gewesen wäre, also ohne wirtschaftliches Risiko. Dass das Thermostat allerdings sofort verstopft, hatte ich nicht erwartet, das dürfte der ZKD - und damit dem Auto - dann den Rest gegeben haben. Friede seiner Asche. Ich werde es nicht noch mal kaufen.
