A controlled-release supplement coolant additive for use in diesel engine coolant systems comprising a core containing at least one supplemental coolant additive (SCA) active component and a polymeric coating material encapsulating said core. The controlled released supplement coolant additive slowly releases the SCA active components to a diesel engine coolant system, thereby delivering an effective concentration level of SCA active components over an extended period. The controlled-release supplement coolant additive maintains a minimum concentration level of active SCA components in the coolant system. Additionally, the controlled-release supplemental coolant additive prevents overdosing the coolant system with particular SCA active components such as nitrates.
