Liqui Moly Radiator CleanerLiqui Moly Radiator Cleaner is a concentrated formula designed to cleanse the cooling circuits. Deposits in the cooling/heating system create blockages for heat exchange and also block thermostat valves and control mechanisms. When engine temperatures are too high, the engine runs uneconomically and suffers excessive wear which can create considerable risk of damage. Liqui Moly Rad Cleaner helps remove deposits containing oil and limescale, and ensures that the engine runs reliably and at the optimum temperature.Features: Concentrated formula designed to cleanse the cooling circuits Removesdeposits containing oil and limescale Ensures that the engine runs reliably and at the propertemperature Does not contain aggressive acids or alkalis
