K-Seal Coolant Leak, 236ml | Multi-use Car Radiator & Head Gasket Repair Sealant

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.

Worked so goo, great value for the money

Good product helppul

Does exactly what its meant to do, very easy to use, just pour into coolant tank.

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!

Didn't worked as expected

Good product as expected

car was leaking coolant slowly, put in and no more warning about coolant low level, been 12 months already, highly recommend

Great product

Seems to stop leaking from plastic header of the radiator.

Fungerade mycket bra. Jag är nöjd. Bara att skaka burke jättenoga först. Sen hel i allt

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.

Utilizzato con molto scetticismo un mese fa su di una fiat punto che consumava da tempo acqua e a freddo andava a tre cilindri perché la candelasi bagnava.. Ha funzionato alla perfezione,il primo giorno ha smesso di andare a "tre" e nel giro di pochi il consumo di acqua si è fermato definitivamente. Al momento altamente consigliato.
