Modern aluminum coolant systems are manufactured using Controlled

Atmosphere Brazing (CAB). Because of the way the aluminum parts are joined,

the outside of the radiator becomes passivated by the air––giving it a natural

protective coating––but the aluminum inside remains unprotected. And that’s a

big problem for heavy-duty engines that call for nitrited coolants.

Aluminum systems and nitrites don’t mix



When nitrited coolants hit unprotected

aluminum, an adverse reaction can occur,

causing increased coolant consumption, pH
imbalance, and in some cases, engine failure.

Conditioners aren't the answer

Some OEMs offer radiator conditioners designed to reduce the risk of adverse chemical reaction. But conditioners aren’t a reliable or effective fix for the problem.
