Radiator 26in x 19in Dbl Pass Chevy 1.5in Inlet

The AFCO RACING PRODUCTS Radiator 26in x 19in Dbl Pass Chevy 1.5in Inlet is purpose-built for high-performance marine and automotive cooling applications where reliability and heat dissipation matter. Whether you're running a freshwater or saltwater boat with a Chevy powerplant, or pushing a performance engine in extreme conditions, this dual-pass aluminum radiator is engineered to handle sustained thermal loads that stock cooling systems cannot. The double-pass design ensures coolant flows through multiple tubes in sequence, maximizing contact time with cooling fins and delivering superior heat rejection compared to single-pass alternatives.

This radiator features a heavy-duty aluminum core construction with a natural finish that resists corrosion in demanding marine environments. The dual-pass core layout allows coolant to make two full passes through the radiator, extracting heat more efficiently and maintaining lower operating temperatures under load. The 1.5-inch inlet accommodates most Chevy engine bay plumbing layouts, with the passenger-side inlet and outlet configuration simplifying installation in standard mounting positions. At 18.11 pounds, the unit remains lightweight while delivering professional-grade cooling capacity—critical for boats where weight distribution and performance tuning go hand-in-hand.

Boaters and performance engine builders benefit most from this radiator when running modified Chevy engines that exceed OEM thermal output, or when operating in extended high-load scenarios where cabin cooling or engine longevity is non-negotiable. The aluminum construction and dual-pass design make it ideal for freshwater lakes, coastal saltwater applications, and drag or performance racing. Verify inlet/outlet hose routing and engine bay clearance before ordering, as the 24 x 8 x 33-inch mounting profile requires proper fitment in your specific boat's engine compartment. For anglers and boaters who demand reliability on the water, this AFCO radiator delivers the thermal management edge that keeps your engine running cool and strong.
