Cooling System Cleaning through the use of a Chelating Cleaner Filter 1999-01-3720
A new method of cleaning cooling systems has been developed that uses a filter with a chelating alkaline cleaner that is released into the cooling system. The cleaner filter is installed in place of the inhibitor filter on heavy-duty engines and left in place for one service cycle. After the service cycle, the cleaner filter is removed, the coolant tested, and the inhibitor filter is reinstalled. This represents a major change in the method traditionally used for cooling system cleaning.
