Description

Fast and Accurate Leak Detection

The Würth Radiator Leak Detection Additive is a special fluorescent agent designed to trace leaks in vehicle cooling systems. When added to the coolant circuit, it enables quick and accurate localisation of leaks under UV or suitable inspection lighting. Even micro-leaks that are otherwise difficult to detect become visible.

Universal Compatibility

Developed for all types of vehicles with water cooling - from passenger carsd to commercial trucks and buses - this additive works seamlessly with standard cooling system fluids. Its 30ml capacity is sufficient for up to 15L of coolant, making it suitable for single-vehicle applications or fleet servicing.

Safe and Practical

The formula is odourless, non-corrosive, and easy to use, ensuring no harmful impact on the cooling system materials. It does not interfere with coolant performance or properties, making it ideal for preventative maintenance as well as diagnostic troubleshooting.

  3. Pour the entire 30ml contents into the radiator or expansion tank.
