Designed for Minor Leaks up to 0.9mm

Bar's Radiator Stop Leak Powder is designed to seal suitable minor cooling-system leaks up to approximately 0.9mm.

As the powder circulates with the coolant, it can reach suitable minor leak paths within compatible parts of the cooling system.

It should not be regarded as a substitute for mechanical repair where a component is severely cracked, damaged or otherwise structurally compromised.

This product is intended for suitable minor cooling-system leaks up to approximately 0.9mm. It should not be relied upon to repair severe cracks, major component damage or substantial cooling-system failures.

Always allow a hot cooling system to cool fully before opening the radiator, expansion tank or any pressurised part of the cooling system.

Check the vehicle manufacturer's requirements and follow the product instructions before use. If the vehicle has suffered significant coolant loss, overheating or suspected major engine damage, the underlying fault should be properly diagnosed.
