Cummins 4058964 Coolant Filter Assembly

The Cummins 4058964 is a genuine OEM spin-on coolant filter designed to protect engine cooling systems from corrosion, cavitation, and particulate contamination. It incorporates a DCA4 chemical additive that releases supplemental coolant additives (SCAs) during operation to maintain liner pitting protection and corrosion resistance. The filter features a 11/16-16 UN-2B thread interface, an outer diameter of 94 mm, and an overall height of 136 mm. It is engineered for heavy-duty diesel applications including construction machinery, commercial trucks, buses, and generator sets powered by Cummins B, C, L, and N series engines. The filter media provides medium filtration efficiency for liquid coolant circuits.
