1955-1957 Chevy TriFive LS and LT Radiator with Auto Trans Fan
If you're swapping an LS or LT powerplant into a TriFive Chevy paired with a 4L60E or 4L80E transmission, keeping oil and coolant temperatures in check becomes critical. This radiator combines a corrosion resistant aluminum core with a slim 16 inch electric fan built to move high volumes of air under sustained load while drawing minimal amperage. Installers will appreciate the direct bolt on fit to 1955 through 1957 Chevy 150, 210, Bel Air and Delray chassis, which preserves the factory under hood layout and avoids custom brackets or tunnel modifications. Built in the USA, each unit meets precise factory mounting points to deliver reliable cooling performance on spirited drives and long highway runs.
Engineered Fit for TriFive Chevy Chassis
This radiator assembly is precision matched to the frame rails of 1955 through 1957 Chevy 150, 210, Bel Air and Delray models, eliminating any need for custom brackets or alterations to the transmission tunnel. By using original factory mounting locations, it maintains proper alignment with 4L60E and 4L80E transmission coolers and radiator hoses, so installers can avoid time consuming mock-ups or rerouted plumbing. The direct bolt-on design preserves the classic under hood appearance and prevents interference with sheet metal or accessory brackets, ensuring a clean, factory-style presentation. Proper alignment also reduces stress on hose ends and seals, minimizing the chance of leaks over many seasons of spirited driving or extended highway cruising. For enthusiasts who demand both authenticity and reliable function, this engineered fit delivers plug-and-play convenience without sacrificing style or performance.
Superior Aluminum Core for Rapid Heat Rejection
Constructed from high grade aluminum, the core offers exceptional thermal conductivity that keeps both coolant and transmission fluid temperatures under control during towing, track days or stop-and-go traffic. The dense array of cooling fins is optimized to increase surface area and promote fast heat exchange, while reinforced end tanks resist the fatigue caused by vibration and thermal cycling. Aluminum's natural corrosion resistance makes this radiator ideal for use in coastal regions or winter climates where road salt and moisture are prevalent, ensuring the core remains leak free and structurally sound. Weighing significantly less than comparable steel and plastic units, the light weight assembly also helps reduce front end mass, which can yield subtle improvements in steering response and fuel economy. This combination of durability and rapid heat rejection keeps engine and transmission operating in their ideal temperature range no matter the demands placed on the system.
Efficient Single Fan Operation with Low Electrical Draw
A slim sixteen inch electric fan is pre-installed to deliver substantial airflow at idle and low road speeds without drawing excessive current from the charging system. The fan is controlled by a temperature activated switch that engages only when medium to heavy load conditions demand additional airflow, so alternator capacity remains available for lighting, audio or other accessories. Blade geometry is tuned to produce strong static pressure, ensuring consistent air movement through the core even in dense traffic or when parked on a hot day. This single fan configuration reduces overall amperage draw compared to dual stack units, which eases the load on belts and pulleys and extends battery and alternator life. Quiet by design, the fan provides confident airflow support without becoming a distracting under hood noise source on highway drives.
Coating Choices for Style and Lasting Protection
Two surface treatments let builders tailor the radiator's appearance to any restoration or custom engine bay theme. The bare aluminum option accepts polish readily, revealing a bright finish that can be refreshed after years of service and accentuates the core’s clean lines. Alternatively, a black epoxy coating provides an additional barrier against moisture, chips and debris, protecting the metal while complementing darker engine compartment color schemes. Both finishes bond securely to the substrate without flaking or peeling, so the radiator retains its factory fresh look through repeated heat cycles and environmental exposure. Whether you prefer a gleaming reflective surface or a stealthy dark tone, these coating options balance aesthetics and protection to suit a wide range of build styles.
