I used as a preventative measure as that particular engine was notorious for headgasket failure and the car is still running in 2022 never having had a problem with the engine except an alternator, so I would say long term damage is ZERO. I have used it in all my cheap runaround cars I have bought as my 3 sons got thier first cars and never had problems with it. Overall it seems to me to be a great product. **Q: Im doing a coolant flush but when i fill the system back up do i fill with plan water or antifreeze to add the k seal** A: fill system up as normal using antifreeze and add k-seal **Q: How much would I need to use for a 1.2L vehicle? Is it the whole bottle or part of the bottle?** A: I used 2 for a two litre car and sorted my issue which was a head gasket problem. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing results *by G***R on 21 May 2026* Well well well, this small bottle of liquid worked perfectly, and months later still no leaks.
