Hey @Bar's Leaks, I really hope you'll see my comment. I have a 2005 Nissan Serena C25. I purchased the car and gave it a total fix up, changed the transmission fluid.The car never gave me any problems untill now it is running and shifting smooth as ever. Knowing it's still a Nissan and they do not have THE best CVT transmission. I thought it would be a great idea to throw in the CVT fix now instead of waiting until it MAY start giving any problems. I do service my car on time. And I do drive it very carefully. I already ordered it from Amazon. What are your thoughts

can i put the bars leaks head gasket fix in my radiator if there is only water in it ? In other words, can i mix water thats already in the radiator with the bars liquid? (there is no coolant in it at the moment)

Tried it twice. Didn't help my intake manifold gasket or radiator, just gunked it up with copper colored particles. Blue Devil worked better, seemed to mix in well and stop leaks, at least for a couple of years
