This product added to the Radiator and circulated by the Engine, dislodges oil deposits and grime. After a Head Gasket failure oil spread through the coolant and settled in the Heater matrix and radiator. This failure stopped internal heat and squashed the water into a smaller and smaller space. The inevitable boil over happens. This liquid can be pumped through the pipes with water to clear blockages, Water flushed out will gradually clear after a few flush and drains. Use the bottle in stages and not all at once. Remember that coolant cannot be simply run into a drain. It must be taken to a local disposal site.
