I would definitely get this again if needed works like a charm.

Funcionó
Funcionó bastante excelente, hay algunos trucos que quizás no sea recomendado o tarde más pero pueden ayudar a que sellé mejor, como esperar a repose totalmente un día con el líquido aún en su interior y volver a repetir el proceso, esperar a que enfríe totalmente (unas 3 horas) y ahora sí hacer el cambio a antifrezze

Worked great for my Rover!
This product worked for my car that has a leaking/blown head gasket. BUT this is NOT a permanent fix!. It lasted 1 year, the first time I added this to the water. So had to purchase this item again to repeat the process. This item came in a much bigger bottle so you only need to use half of it. It is very easy to use, Just follow the instructions on the back of the bottle. But one thing I didn't bother doing was removing the thermostat before starting the job, I just emptied some of the coolant from the bottom of the radiator, so to leave room in the water system for the Blue Devil liquid when pored in. It worked 100% for me on my Rover 416, year 1998 It may not work for all, but I suppose its worth ago to save the hefty price of paying for a new head gasket ? No complaints, only praise = 5 stars
