It’s hard to locate small leaks caused by stone chipping, porous soldered connections or hairline cracks in the cooling system on water-cooled engines – the only clue is in the reduced coolant level. This dispersion completely seals this type of leaks immediately and safeguards the combustion chamber against damage caused by coolant ingress. Compatible with all conventional coolant additives and antifreezes. Can also be used preventively. For all coolant and heating systems with and without water filters. Also for aluminum and plastic radiators. 150ml is sufficient for up to 7L of coolant; 250ml is sufficient for up to 10L of coolant.
