Had my doubts, but this stuff stopped a very persistent leak that was making me refill my expansion tank every day! Not a drop since then (about three months now). Definitely worth every penny and saved me from spending the $2K that the mech wanted to replace all the hoses in and around the engine (I have a Jag). I keep an extra bottle in my garage now just in case.
