K-Seal Permanent Head Gasket & Block Repair

K-Seal ULTIMATE is the simple, permanent fix for blown head gaskets, cracked heads and blocks, and porous engine blocks. Our unique formula works with all water-cooled engines – there’s no need to drain or flush your cooling system, and it doesn’t matter what kind of antifreeze or coolant you’ve used previously. Simply shake the bottle, pour K-Seal ULTIMATE into your cooling system, and you’re back on the road. Just one bottle of K-Seal ULTIMATE is enough to fix blown head gaskets and cracked heads in cars, SUVs and small trucks. For larger engines, simply use two bottles.
