Shake the bottle well and add Radiator Stop Leak to the cooling system either via the expansion tank (if part of the system circuit) or directly into the radiator. If necessary, top up the system with coolant. Run the engine for approximately 5 minutes to circulate and stop the leaks. One bottle of 300ml is sufficient for cooling systems with capacities ranging from 5 to 12 liters.
