What ASTM and TMC specifications does FINAL CHARGE Coolant meet?
FINAL CHARGE Coolant meets leading ASTM coolant specifications, including ASTM D-4985 and ASTM D-3306. However, it should be noted that ASTM has not established a specification for extended life coolants. Instead, current ASTM specifications are more geared toward conventional coolants that have a limited service life, typically 3-year/36,000 mile. As with ASTM, TMC has not set coolant specifications addressing extended life coolants. TMC RP-329, a long-standing heavy-duty coolant standard, is the specification for a conventional low silicate coolant that is precharged with a Supplemental Coolant Additive (SCA) containing nitrite or nitrite and molybdate. While FINAL CHARGE Coolant definitely meets the performance requirements of TMC RP-329, it does not meet the chemical requirements of the specification. The reason FINAL CHARGE Coolant does not meet the chemical requirements of TMC RP-329 is that FINAL CHARGE Coolants proprietary corrosion inhibitor system does not contain nitrite. Wi
