The DAC Radiator Sealant is suitable for use in all water-cooled, closed cooling systems (commercial vehicles, passenger cars, and other industrial heat exchangers). It reliably, quickly, and easily seals critical hairline cracks and minor leaks. It can also be used preventively.
 Advantages: In internal combustion engines, a large portion of the chemical energy bound in fuel is converted into heat, which must be dissipated. A functioning cooling system is crucial for the operational reliability of engines! It saves expensive repairs. It prevents coolant loss and thus protects against engine damage.
