Cooling sealant for winter

The Carbon Fiber Block Seal Head Gasket & Cooling Sealant is formulated to seal coolant leaks in radiators, heater cores, freeze plugs, gaskets, intake manifolds, cylinder heads and engine blocks. It is anti-freeze compatible and doesn’t need to be removed after a repair. The formula combines liquid glass with aramid and refractory fibers reinforced with carbon fiber to bridge larger leaks and create a seal.
