Irontite All Weather Seal Coolant Stop Leak, Pint 455 ml– Pour-and-Go Radiator & Head Gasket Leak Sealer

Irontite All Weather Seal is a pour-and-go coolant stop leak you add directly to the radiator—no flushing required. It blends with coolant/antifreeze to help stop existing and future coolant leaks, including head/intake gasket leaks, radiator leaks, and other cooling system leaks. It’s formulated for extreme weather (hot or cold), uses micro fibers to detect and stop leaks at the source, and is designed to not clog heater cores while also lubricating water pump seals.
