K-Seal’s unique formula is the only coolant leak and head gasket repair fluid to be scientifically tested and compliant with the ASTM D3147 standard. We are so confident K-Seal will provide a fast and permanent repair that we will provide another bottle free of charge if a leak previously sealed with K-Seal returns.
Note that K-Seal cannot fix some larger holes and cracks, and we can only offer a replacement bottle where a previous application of K-Seal has fixed a leak but subsequently failed.
