Description: Radiator Stop Leak is a safe and efficient method of sealing leaks in the coolant system. Added to coolant, it flows through leak points in the coolant system, quickly and completely plugging them. As coolant flows through the hole in the system, particles build on each other around the hole until it is completely plugged.
Features & Benefits:
Provide temporary leak-stop protection to radiators and cooling systems
Compatible with most types of Antifreeze
No environmentally harmful dyes
Directions: Add contents with engine cool, remove radiator cap and start engine. Turn on heater and run about 5 minutes. Shake bottle well and pour entire contents into radiator. Make sure radiator is filled to normal level and replace radiator cap. On bottle is enough for systems up to 24-quart capacity. If leak doesn’t stop, mechanical attention is needed.
Application: Safe for use in engine systems using antifreeze
