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.

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 a 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.

This radiator is ideal for dedicated motorsport applications, heavily modified street platforms, or tactical/emergency vehicles requiring redundant cooling capacity. The dual-pass configuration ensures consistent core saturation and reduces hot spots that compromise longevity, making it a reliable choice for those who demand the best in thermal management.
