16-Pass Electra-Cool Rep lacement Core -6AN

The 16-Pass Electra-Cool Replacement Core -6AN from DERALE is a high-efficiency fluid cooler engineered for vehicles requiring robust thermal management in demanding conditions. This replacement core serves as the heart of any aftermarket cooling system, designed for users who push their engines hard—whether in street performance, towing, or track applications. The universal design makes it an ideal retrofit solution for custom cooling setups where OEM capacity falls short.

Built with a 16-pass tube configuration, this cooler maximizes fluid dwell time across the cooling matrix, dramatically improving heat rejection efficiency compared to fewer-pass designs. The copper and aluminum construction provides superior thermal conductivity and corrosion resistance, ensuring years of reliable performance even with aggressive coolant formulations or synthetic fluids. The 6 AN male inlet and outlet ports deliver compatibility with modern braided hose systems, allowing clean plumbing integration into any custom cooling loop while minimizing pressure drop.

Enthusiasts upgrading transmission coolers, engine oil coolers, or dedicated auxiliary cooling circuits benefit most from this replacement core's compact 13 x 10.375 x 1.75-inch profile, which fits tight engine bays without sacrificing cooling capacity. Installation is straightforward—simply replace your existing core within your cooler tank assembly or integrate into new construction. The natural aluminum finish resists oxidation and pairs well with modern engine compartment aesthetics. Whether you're rebuilding a damaged cooler or scaling up cooling performance, the 16-Pass Electra-Cool Replacement Core delivers proven thermal efficiency in a universal platform.
