Aluminum Radiator GM 67-69 Camaro LS Engine

The Aluminum Radiator GM 67-69 Camaro LS Engine from Northern Radiator is purpose-built for classic Camaro restorers and LS swap enthusiasts who demand modern cooling capacity without sacrificing original aesthetics. This radiator bridges the gap between first-generation Camaro platform constraints and contemporary LS engine heat rejection requirements, making it an essential upgrade for anyone transitioning from carbureted or fuel-injected small-block power to the higher-output LS family. Whether you're building a restomod or modernizing a classic muscle car, this aluminum core delivers the thermal performance needed to keep an LS engine operating at optimal temperatures under street and moderate performance driving.

Constructed from lightweight aluminum with enhanced core density, this radiator maximizes cooling efficiency while reducing overall system weight—a critical advantage in vintage chassis where original iron radiators contributed significant unsprung mass. The compact 22.5-inch width and 30.5-inch height allow bolt-in fitment within the stock 1967–1969 Camaro engine bay, eliminating the need for frame or core support modifications that plague many LS conversions. Northern Radiator's engineering ensures compatibility with LS engine thermostats and water pump configurations while maintaining proper flow rates and pressure ratings; at 17 pounds, the aluminum construction saves approximately 30 pounds compared to period-correct iron alternatives, improving weight distribution and handling balance.

This radiator is ideal for second-generation (1970–1981) Camaro LS conversions as well as those working within strict first-gen platform constraints, including restorations aiming for original-style appearance without compromising modern engine reliability. Installation pairs seamlessly with LS water pumps, electric fans, and aftermarket coolant hoses—verify your specific LS variant (Gen III, Gen IV, Gen V) for pump mounting configuration before ordering. Proper radiator positioning ensures adequate airflow through the core; users should confirm available clearance around the thermostat housing and intake manifold before final mounting to avoid interference with accessories or hoses.
