LS and LT Radiator with Fan for 1955-1957 Chevy TriFive 150/210/Bel Air/Delray
When fitting an LS or LT powerplant to a 1955 to 1957 TriFive Chevy mated to a 4L60E or 4L80E auto transmission the stock cooler often allows oil and coolant temperatures to rise under sustained load. The 1955 to 1957 Chevy Radiator (Auto Trans) with Fan combines a corrosion resistant aluminum core and a slim 16 inch electric fan for reliable thermal management. It bolts directly to 1955 to 1957 Chevy 150 210 Bel Air and Delray frames without any tunnel modifications preserving fluid routing and under hood layout and drawing less amperage than twin fan packages to keep alternator load light. Built in the USA each unit delivers precise fit quality and dependable performance on spirited drives and extended highway runs.
Engineered Fit for TriFive Chevrolet Frames
This radiator assembly is tailored to bolt directly onto 1955 through 1957 Chevy 150, 210, Bel Air, and Delray chassis without altering the transmission tunnel or adding brackets. By matching the factory mounting points, it ensures perfect alignment with 4L60E and 4L80E transmissions, eliminating the need for hose rerouting or custom shims. Installers gain a true plug and play solution that cuts mock-up time and reduces the risk of leaks caused by misaligned connections. Retaining the original under hood layout also preserves the classic appearance, so restorations and modern conversions blend seamlessly. The precise fit reduces stress on seals and hoses, contributing to a more reliable installation over the life of the vehicle.
Aluminum Core Performance and Durability
Constructed from quality aluminum, the core offers exceptional heat transfer rates compared to traditional steel or plastic radiators, keeping transmission oil and coolant temperatures in check under heavy load. Its inherent resistance to corrosion makes it ideal for use in coastal environments and winter conditions where road salt and moisture can accelerate decay. The lightweight nature of the aluminum core also trims front-end mass, which may lead to subtle improvements in handling and efficiency. Internally, a dense fin configuration and reinforced end tanks resist vibration and thermal cycling encountered during spirited driving or towing. This combination of strength and thermal capacity delivers consistent cooling performance mile after mile.
Single Fan Efficiency and Electrical Savings
A slim 16-inch electric fan is pre-installed on the radiator, engineered to push a high volume of air at low road speeds and during idle conditions without drawing excessive current. Because it consumes less amperage than dual-fan setups, alternator capacity is freed for headlights, audio systems, or other accessories without risking overload. A built-in thermostat switch engages the fan only when needed, maintaining ideal oil and coolant temperatures while minimizing noise on highway runs. The fan's blade profile is optimized for static pressure, delivering confident airflow even in dense traffic or stop-and-go scenarios. This efficient design reduces electrical load and enhances overall system reliability.
Surface Finishes for Protection and Style
Choose between a bare aluminum core that can be polished for a bright, reflective surface or a black epoxy coating that provides an extra shield against moisture, chips, and road debris. The natural finish highlights the clean lines of the radiator, making it easy to restore to like-new condition with a simple polish after years of service. Conversely, the epoxy option offers added toughness, resisting environmental wear and fading while complementing dark engine bay themes. Both finishes adhere strongly to the underlying material, ensuring long-lasting protection without flaking or peeling. This range of surface treatments lets builders match the radiator to any restoration or custom aesthetic without sacrificing durability.
