K-Seal is a pour-and-go permanent coolant leak repair fluid. It seals leaks in the radiator, head gasket, engine block, heater core, water pump, and freeze plugs without draining, flushing, or removing the thermostat.

The ceramic and copper formula is safe for all water-cooled engines and works with any antifreeze. Just shake the bottle, pour it into the cooling system, and run the engine; the sealant finds and seals holes and cracks, typically within 7–10 minutes. It's a cost-effective alternative to expensive mechanical repairs, backed by a lifetime guarantee for the engine.

Verified fitment

8 fl oz bottle treats cooling systems up to 20 quarts (20 liters). Heavier trucks and large commercial vehicles may require the 16 oz Heavy Duty size. Not for use in systems with existing stop-leak products; check compatibility.
