Custom Aluminum Radiator Kit 19 x 31

The Northern Radiator Custom Aluminum Radiator Kit 19 x 31 is purpose-built for serious enthusiasts and mechanics seeking reliable engine cooling in compact engine bays or retrofit applications. This aluminum core design addresses the thermal demands of modified and classic vehicles where stock cooling capacity falls short or space constraints demand a purpose-engineered solution.

Constructed with lightweight aluminum core and tank materials, the Northern Radiator 19 x 31 radiator kit maximizes cooling efficiency while minimizing overall weight—a critical advantage in vehicles where every pound matters for suspension geometry and acceleration. The aluminum construction provides superior thermal conductivity compared to traditional copper-brass designs, effectively reducing coolant temperatures during demanding conditions.

This radiator kit is ideal for builders working on Chevy small-block applications, street rods, and vintage engine swaps where OEM cooling capacity proves inadequate for performance modifications or modern traffic conditions. With overall dimensions of 22 x 4.2 x 32.2 inches, it is engineered to fit tight engine compartments where dimensional precision is crucial for installation success.
