Product Details

Universal Radiator Sealer (AS127) by Prestone®. 14.5 oz. Super Radiator Sealer's special formula helps seal larger size leaks. Its unique combination of natural and synthetic components provides the ability to seal leaks.



  • Seals without interfering with the flow through the radiator and heater core tubes
  • Patented formula provides a strong durable seal
  • Quickly seals large leaks in radiators, heater cores and water pumps
  • What makes this possible is the size, strength, and durability afforded by fibrillated Kevlar particles - the same materials in bullet proof vests
