1955-1957 Chevy 150/210/Bel Air/Delray LS and LT Engine Swap Radiator
When dropping an LS or LT powerplant into a TriFive Chevy and pairing it with a 4L60E or 4L80E transmission, keeping both coolant and transmission fluid temperatures in check is essential. The 1955-1957 Chevy Radiator (Auto Trans) with Fan delivers a corrosion resistant aluminum core paired with a slim sixteen inch fan that moves high volumes of air while drawing minimal amperage. Built for 150, 210, Bel Air and Delray models, the assembly preserves factory mounting points for a direct bolt on fit and maintains proper alignment with transmission coolers and hoses. This plug and play design helps installers avoid custom brackets or tunnel alterations so the engine bay stays true to its original appearance.
Precision Fit for TriFive Chevy LS and LT Engine Swaps
This radiator assembly is engineered to align precisely with the frame rails of 1955 through 1957 Chevy 150, 210, Bel Air and Delray models, allowing LS and LT powerplants to drop in without fabrication. By preserving the original mounting points, it maintains correct orientation for both the coolant hoses and the automatic transmission cooler lines, eliminating the need for custom brackets or alterations to the transmission tunnel. Installers benefit from a true plug and play solution that keeps the under hood layout intact and prevents interference with sheet metal or accessory brackets. The precise fit also minimizes stress on hose ends and seals, reducing the risk of leaks and avoiding unexpected service issues during spirited driving or long highway runs.
Aluminum Construction for Rapid Heat Rejection
Constructed entirely from high quality aluminum, this radiator core excels at transferring heat away from both engine coolant and transmission fluid under sustained load. Aluminum's superior thermal conductivity accelerates the dissipation of excess heat through a dense fin array that maximizes surface area and promotes efficient airflow. Unlike heavier steel or composite units, the all-aluminum assembly also reduces front end mass, contributing to more responsive steering feedback and potentially improved fuel efficiency. In addition, the metal's inherent corrosion resistance ensures durable performance in harsh environments, whether battling road salt in winter or moisture in coastal regions.
Integrated Fan Design for Efficient Airflow and Low Electrical Draw
A slim sixteen inch electric fan is pre-installed to provide effective cooling at idle and low speed operation without overloading the charging system. The temperature-activated switch engages the fan only when heat buildup demands extra airflow, ensuring alternator output remains available for lighting and accessories. Carefully tuned blade geometry produces strong static pressure so air moves consistently through the core even in stop-and-go traffic or when idling on hot days. This single fan configuration draws less current than twin-blade setups, reducing wear on belts, pulleys and the battery while maintaining quiet operation during both city driving and highway cruising.
Surface Treatment Choices for Protection and Appearance
Builders can choose between a classic bare aluminum finish or a durable black epoxy coating to match the style of any restoration or custom build. The natural aluminum option readily accepts polish, allowing the core to shine and reflect engine bay lighting while retaining easy upkeep over time. The black epoxy treatment adds an extra barrier against chips, debris and moisture, helping to preserve the radiator's integrity and blend with darker engine compartment themes. Both finishes bond securely to the aluminum substrate, resisting peeling or flaking through repeated heat cycles and environmental exposure for lasting good looks and reliable performance.
