Aluminum Radiator 61-65 Impala w/500 Steer Box

The Aluminum Radiator 61-65 Impala w/500 Steer Box by COLD CASE RADIATORS is engineered for classic Chevy Impala owners who demand superior cooling performance without sacrificing authenticity or fitment. Built as a direct replacement for 1961–1965 Impala models equipped with 500-series steering boxes, this all-aluminum unit solves the chronic overheating issues that plague original cast-iron radiators, especially when upgrading to modern engine builds, electric fans, or tackling highway cruising in warmer climates. Whether you're restoring a show-quality muscle car or optimizing a restomod for street duty, this radiator delivers the thermal capacity and reliability needed for consistent performance.

Cold Case's aluminum construction significantly outperforms traditional copper-brass cores in both weight and heat dissipation efficiency, shedding approximately 25–30 pounds compared to stock while improving cooling capacity by up to 40 percent. The three-row core design maximizes coolant flow path length without adding bulk, allowing tighter radiator mounting within the original 1961–1965 Impala engine bay constraints. The 500-series steering box clearance engineering ensures zero interference with power steering plumbing—a critical consideration often overlooked in universal aftermarket units. Hard-soldered aluminum construction eliminates solder leaks and vibration-induced failures, while the included mounting tabs and fittings maintain compatibility with original hose routing and water pump configurations.

First-generation Impala enthusiasts—from weekend cruisers to show car builders—rely on this radiator to eliminate cooling bottlenecks during idle traffic or sustained high-RPM driving. Installation is straightforward for anyone with basic mechanical knowledge; the radiator bolts directly into factory mounting locations without modifications to frame or core support. This unit pairs seamlessly with both stock 283/327 engines and modern LS swaps, making it a go-to choice for restomod conversions where original cooling capacity falls short. At 48 pounds and measuring 16 by 26 by 36 inches, the radiator balances structural rigidity with manageable weight, preserving the classic profile that defines 1961–1965 Impala aesthetics.
