HARDEX Copper Radiator Stop Leak 24.8g

Product Description:

This fast-acting powder formulation is infused with copper particles to quickly seal hairline cracks and pinhole leaks within automotive radiators and cooling systems. It circulates safely with the coolant, locating the leak site and forming a durable, heat-resistant copper metallic patch upon exposure to air. It is carefully engineered to flow smoothly without clogging delicate heater core passages.
