Use the manufacturer product information when checking treatment rate and coolant compatibility

Compatibility and Fitment

Check cooling system capacity before use, then match one bottle to systems up to 12 litres. If the system has already lost fluid, refill with a suitable anti-freeze anti-boil coolant before returning the engine to service.

Compliance and Safety

Only open the cooling system when it has cooled enough to handle safely. Shake the bottle before use, add it directly to the radiator, and treat this product as a temporary repair rather than a substitute for mechanical fault diagnosis.

Trailer Applications

Trailer and fleet workshops keep radiator stop leak 375mL for service vehicles, yard trucks, support equipment and engines that develop small cooling system leaks. It suits quick workshop response when coolant loss needs temporary control before proper repair.
