GM Radiator Dual Pass 19 x28 Interchangable Inlet

The GM Radiator Dual Pass 19 x 28 Interchangeable Inlet by Northern Radiator is a high-capacity cooling solution engineered for General Motors vehicles requiring superior heat dissipation during performance driving or heavy-duty conditions. Built for enthusiasts who demand reliable engine temperature management, this radiator addresses the cooling demands of modified or stock GM powerplants where factory cooling capacity falls short.

The dual-pass design maximizes coolant velocity and contact time within the core, directly translating to more efficient heat rejection and stable operating temperatures under sustained load. Dual-pass radiators force coolant through the core twice before exiting, nearly doubling the thermal transfer efficiency compared to single-pass designs—a critical advantage in street performance, track use, or towing scenarios. Northern Radiator's construction uses proven aluminum core and tank materials with brazed seams to withstand pressure cycling and thermal stress, ensuring longevity without coolant leaks or internal corrosion.

This radiator is ideal for small-block and big-block Chevy applications, LS engine conversions, and street rods where cooling capacity and installation flexibility matter. The 19 x 28-inch core dimensions provide substantial surface area for air-to-coolant heat exchange, while the interchangeable inlet configuration delivers flexibility for various plumbing layouts and engine bay constraints.
