Deposits in the cooling/heating system create blockages for heat exchange and they also block thermostat valves and control mechanisms. When engine temperatures are too high, the engine runs uneconomically and suffers excessive wear at considerable risk of damage. LIQUI MOLY Radiator Cleaner removes deposits containing oil and lime, and ensures that the engine runs reliably and at the optimum temperature. Does not contain aggressive acids or alkalis.

Add contents to the cooling water. Run the heating system. Depending on the degree of contamination let the engine run approximately 10 to 30 minutes. Drain the cleaner and flush out the cooling system with water. Fill the cooling system according to the manufacturer's instructions. The content (300 ml) is sufficient for 10 litres of water.
