MAINTENANCE If coolant is added between drain intervals, additional SCA will be required. Check the coolant DCA concentration level anytime coolant is added to the system. The SCA concentration must not fall below 0.13 units per liter or exceed 0.5 units per liter [0.5 units per U.S. gallon or exceed 2 units per U.S. gallon]. NOTE 1 - After draining and replacing coolant, always precharge the cooling system to maintain the SCA concentration between 1.0 and 2.0 units per 3.8 NOTICE: When performing service which requires draining the cooling system, discard the coolant.
Reusing coolant can introduce contaminates or over concentrated chemicals, resulting in premature failure of cooling system components. NOTE 2 - To precharge cooling systems larger than 114 Install appropriate service filter listed in the above table based on cooling system capacity.
