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

efficace dès la 1ere utilisation. plus de problemes de fuite depuis. un miracle ? pour le prix cela vaut le coup de l'essayer plutot que d'engager de gros frais pour les réparations.

I had observed oil leak signs in the coolant, Probably faulty oil cooler gasket or Engine head gasket. I poured this liquid to the radiator and drove my Thar crde for almost 30minutes. Next day had gone for 400kms drive as well. No further oil leakage. Coolant looks clean now. Its been almost 3 weeks now. Oil mixing with coolant has stopped perfectly.
