K-Seal Ultimate is the most simple head gasket repair product available on the market. No need to worry about what kind of antifreeze or coolant is in the system or what kind of engine or vehicle you are trying to fix. K-Seal Ultimate can also be used if you just have water in the cooling system.1 bottle is sufficient for all cars, SUVs and light trucks. For larger engines such as HGVs use 2 bottles. Just shake the bottle, pour it into the cooling system where you normally top up, and drive. Nothing could be easier. No special tools or procedures required.

K-Seal Ultimate is also completely safe to use in any cooling system. It has been independently tested by Brighton University Engineering Division to meet the US standard ASTM D-3147.That means it will seal holes up to 0.635mm but it will not clog even the narrowest waterways in the cooling system. K-Seal Ultimate is backed by over a decade of product development and comes from the global coolant leak repair specialists. Don’t just seal it, K-Seal it!
