Race Pro Radiator 31 x 19 GM

The Race Pro Radiator 31 x 19 GM is a high-performance cooling solution engineered for serious street and track applications on General Motors vehicles. Built by Northern Radiator, this unit replaces factory cooling systems that cannot handle the thermal demands of modified engines, forced induction, or sustained high-RPM operation. Whether you're running a tuned LS engine, a supercharged small-block, or pushing higher coolant flow through an aggressive fuel curve, this radiator is designed to keep cylinder head temperatures in check and maintain safe operating parameters under extreme conditions.

This radiator features a 31 x 19 core dimension, optimizing surface area for maximum heat rejection while fitting within OEM engine bay constraints. The Race Pro design incorporates multi-pass tube construction and enhanced fin density to accelerate coolant velocity and improve heat transfer efficiency—critical when intake air temperatures spike or ambient conditions limit natural convection. At 27 pounds and measuring 22.5 x 10 x 34.5 inches, the unit balances substantial cooling capacity with practical installation geometry, allowing direct bolt-in compatibility on many GM platforms without requiring extensive fabrication or custom mounting brackets.

Mechanics and engine builders favor Northern Radiator's Race Pro line for naturally aspirated performance builds, turbo and supercharger conversions, and vehicles running extended track sessions or towing heavy loads. This radiator is particularly effective in second-gen Camaros, Firebirds, and full-size pickup trucks where factory cooling became the bottleneck to reliability. Verify hose fitting locations and inlet/outlet port positioning against your specific GM generation and engine bay layout before ordering; professional installation ensures proper coolant flow direction and eliminates air pockets that can cause localized boiling and hot spots.
