Additive GOODYEAR Radiator Stop Leak 300ML

With its unique and exclusive formula, GOODYEAR's radiator leak sealant additive, enriched with active surface agents and suspended metal and polymer particles, has been developed to quickly and permanently seal small cracks and punctures in your vehicle's cooling system without changing the colour or appearance of the antifreeze.
