It genuinely works!
It’s amazing stuff. Sorted a mysterious coolant leak in minutes. First time since I got the car that I haven’t had to top up after a long journey. Seems to be a permanent fix too.

Actual long term solution for minor coolant leaks in hard to reach places
Put this in a Citroen DS3 1.6 vti a year ago as it had a small leak on the oil cooler. After a year the coolant has only started to drop again - ordered some more, better than removing the manifold etc!

Good stuff
My wifes old fiesta was losing water every day I had to top up the header tank every day before she went out and we were told it was a crack in the head gasket but since I put this stuff in the header tank it has not lost any water so I must presume it has worked but I suppose it has worked
