This product is intended for suitable minor cooling-system leaks. It should not be regarded as a substitute for mechanical repair where a radiator, hose, gasket, water pump or other cooling-system component is severely damaged, cracked or structurally compromised.
Always allow the cooling system to cool fully before opening the radiator, expansion tank or any pressurised part of the system. Follow the product instructions and check the vehicle manufacturer’s requirements before use.
