BlueDevil Products 38386 Head Gasket Sealer - 1 Quart

Works excellent thanks

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

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

My car is Old AU Ford 2000 model Ute , Australian made and one day I checked my water level and I forgot to put the lid or cover back . And I was driving for 3 days delivering goods and the sudden steaming coming out from the engine , when I opened i was shocked and I pour water in and since then leaking radiator plus loosing more engine oil and my friend told me to older Blue Devil . We follow the instructions and now my car back to normal , Blue Devil is real devil and Awesome
