Our radiator stop leak powder contains wood powder, wood chips and metal corrosion inhibitors. It quickly locates and seals leaks in radiators, heater cores and freeze plugs. Ensure the engine is cool, remove the cap, check water level, slowly pour powder into the radiator, fill to proper level, replace the cap, run the engine to circulate water for 15 minutes until heated. Add more if still leaking. It forms an ultra-thin seal resistant to heat, pressure and vibration.
Supplier availability is checked again at checkout. Supplier stock is not reserved until fulfillment is confirmed.
