Deposits in the cooling/heating system form barriers to heat exchange, block thermostatic valves and regulation mechanisms. Excessively high engine temperatures make the engine work inefficiently, with high wear and a high risk of damage. Radiator cleaner safely removes these dangerous deposits and ensures optimum engine temperature and operational safety. Application: For all coolant and heating systems. Does not contain any aggressive acids and alkalis. 300 ml sufficient for 10 l cooling water.
