Is RMI-25 a good Supplemental Coolant Additive (SCA) for my diesel engine?

Yes it is! RMI-25 Cooling System Treatment is a perfect Supplemental Coolant Additive!

What is a Supplemental Coolant Additive (SCA)?

SCAs, or Supplemental Coolant Additives, are solutions added to the coolant stream to provide, as the name suggests, supplemental anti-corrosion and cavitation (or liner pitting) protection for diesel engines having pressed-in wet sleeve cylinders. Liner pitting is a significant and very costly problem in heavy-duty diesel-engine vehicles.

SCA is required in all diesel engines with wet sleeves (press-in cylinder liners). We recommend RMI-25 Cooling System Treatment as an SCA for all diesel and gasoline engine cooling systems, whether they have wet-sleeve liners or not. SCA should be added to your antifreeze solution based on diagnostic testing results.

Other, conventional SCAs, that contain silicate, borate/nitrite or molybdate/nitrite/phosphate are designed to inhibit cavitation, erosion, corrosion, and scale formation. These conventional additives can be applied in a few ways; either bottled liquid added directly to the cooling system via the radiator or coolant recovery tank, or via a SCA coolant filter, or both. In these instances, testing for correct SCA content must be done on a regularly scheduled basis, and the correct amount of conventional SCA added as needed, based on the cooling system capacity and test results.

Note: Other SCAs do not contain a cleaner and their inherent rust and oxidation inhibitor will only work effectively in a clean system. Many users of conventional SCA’s often overdose their contaminated cooling system in an attempt to increase its effectiveness. The overdose issue results in an overcharged system and can cause cooling system problems (green goo/additive dropout and solder bloom). It is critical that a test MUST BE DONE and the correct amount of SCA be used. But the issue of an unclean cooling system remains…

RMI-25 contains a very effective system cleaner and does not use silicates, borates, nitrites, or molybdate/nitrite/phosphate chemistry which are found in most SCAs. These elements can be harmful to the environment, and depleted/used conventional SCA coolant/antifreeze must be managed as a hazardous waste. RMI-25 eliminates the many problems which can occur with products adopting these chemicals in their formulation. Find out more…
