LIQUI MOLY Radiator Cleaner — Cleaner for oily and lime deposits in cooling and heating systems. Loosens contamination for subsequent flushing; it is not coolant or a leak sealer.

300 ml treats 10 l of coolant. Turn on the heater and run at operating temperature for 10–30 minutes according to contamination. Drain the mixture, flush thoroughly and refill as specified by the vehicle maker. Do not open a hot system.
