Coolant can unknowingly leak out of the cooling system through small pinholes, caused by road debris impacting on the radiator. The loss of coolant will reduce cooling system efficiency and possibly cause engine overheating.
Radiator Stop Leak will plug the pinholes in the radiator, without clogging the cooling system passages. A radiator re-core can then be avoided.
Ensure the coolant level is above the radiator core. Run the engine until the coolant is hot(the thermostat opens). Shake the product container thoroughly. Pour the entire container of Radiator Stop Leak into the radiator. Run the engine for 10-15 minutes to ensure the product is circulated throughout the cooling system. Leave Radiator Stop Leak in the cooling system to guard against further leaks. Do not add product to the overflow tank. Avoid contact with the skin. Wash skin with soap and water after handing. Keep out of reach of children. Don’t swallow and keep away from fire. Please do not mix with hard water, ground water or mineral water.
