GM Radiator 19.5625in x 29in Dual Pass

The GM Radiator 19.5625in x 29in Dual Pass from AFCO Racing Products is a high-performance cooling system component engineered for serious motorsport and heavy-duty applications requiring precision thermal management. Built to exacting standards by AFCO—a manufacturer with decades of racing pedigree—this dual-pass radiator addresses the thermal demands of high-output engines where standard cooling solutions fall short. Whether you're running a competition engine, a heavily modified street platform, or a tactical/emergency vehicle requiring redundant cooling capacity, this radiator delivers the engineering reliability you expect from purpose-built thermal systems.

The dual-pass design optimizes coolant flow velocity and dwell time within the core, maximizing heat rejection across a wide temperature operating window—critical when cooling capacity margins are tight or ambient conditions are extreme. At 22.2 lbs and measuring 19.5625 inches wide by 29 inches tall, this radiator balances substantial surface area with practical installation footprint, fitting GM platform engine bays without requiring extensive fabrication. The aluminum construction and robust internal passages are engineered to handle sustained high-flow circulation and elevated system pressures typical of turbocharged, supercharged, or race-prepped powerplants, while the dual-pass configuration ensures consistent core saturation and reduces hot spots that compromise longevity.

This radiator is ideal for dedicated enthusiasts, emergency responders, and motorsport operators who cannot tolerate cooling system compromise. Installation requires compatibility verification with your specific GM engine bay layout and hose routing configuration—mount dimensions and connection ports should be confirmed against your vehicle's thermal system schematic. The 23.5 x 7.5 x 32-inch shipping profile reflects the core's physical presence; proper mounting brackets and adapter fittings may be required depending on your platform. For maximum effectiveness, pair this unit with a quality thermostat, coolant flow optimization, and fan control strategy matched to your engine's thermal profile.
