    Great product!

    This stopped a very minor head gasket leak in an older audi within 5 minutes. So far it has been a week and not one drop of lost coolant, no sign of overheating, and zero bubbles in the coolant tank. I cautiously used just a half bottle for a four cylinder as others have recommended and it has worked properly. The coolant has turned darker and I will leave it on over the course of the summer.

    Did not work for me.

    I used this product with a lot of positive spectations, but it did not work. I used it trying to fix a headgasket on my 1995 Land Rover Discovery, the pressure in the system continues, so I will have to change the headgasket on my engine.

    Did not make it worst but didn't fix the problem either

    Did not fix my leaky head gasket problem in my 2006 Scion tc After a few hundred miles this just got spit out of the overflow tank reservoir and I still ended up losing coolant which I have to refill once a week.

    I would say that this quality merchandise would work in the right settings, mine was just unfixable that way. It did cause my engine to go to a cooling cycle which is incredible.
