Supplemental Coolant Additives (SCAs)

SCA is required in all diesel engines with wet sleeves (press in cylinder liners). We recommend RMI-25 Cooling System Treatment for all diesel and gasoline engine cooling systems, whether they have wet sleeve liners or not.

SCA should be added to your anti-freeze solution based on diagnostic testing results. Other SCA's, which contain silicate, borate/nitrite or molybdate/nitrite/phosphate are designed to inhibit cavitation, erosion, corrosion, and scale formation. These additives can be applied in two ways; either bottled liquid or via a coolant filter treated with SCA. Testing for proper SCA content should be done on a regularly scheduled basis and the proper amount of SCA added as needed based on cooling system capacity. Note: "Other" SCA's do not contain a cleaner, and the rust & oxidation inhibitor will only work effectively in a clean system.

The overdose of other SCA's results in an overcharged system and can cause cooling system problems (green goo or solder bloom). This is the reason a test MUST BE DONE and the proper amount of SCA must be used. RMI-25 does not use silicates, borates, nitrites, or molybdate/nitrite/phosphate chemistry. Therefore it also eliminates the many problems which may occur with products using those chemicals in their formulation. RMI-25 is safe for all metals, plastics, hoses and seals. It is compatible with all types of antifreeze/coolant solutions and metal-based stop leaks.
