Having tried a few radiator cleaners this Liqui Moly is the best I've tried so far. Had a 206 that had head gasket failure in its past. The coolant hoses were lined with a horrible sticky paste. Used as per instruction car upto operating temp heater on etc then pour in and leave to run for 10-30 mins. After 30 mins the inside of the pipes were like new. Will be buying from now on when needed. Always have one on the shelf

Does wonders. Used on my a4 b7 which had water used instead of proper coolant and heating stopped working completely! I've cleaned auxiliary heater separately with a pump and kettle as a water heater and let ir run for half an hour. Now works just like new!
