1955-57 Chevy 150/210/Bel Air/Delray Radiator for LS and LT Swaps (Manual Trans)
Whether you are installing an LS or LT engine into a TriFive Chevy chassis this 1955-1957 Chevy Radiator (Manual Trans) addresses the critical need for reliable cooling in manual transmission applications. Its full aluminum tube and fin core and precisely TIG welded tanks deliver rapid heat rejection while resisting corrosion from chassis flex and road salt. Featuring a direct fit design that matches factory inlet, outlet and mounting points on 150, 210, Bel Air and Delray bodies, it installs without cutting or extra brackets. Each weld undergoes airtight integrity inspection to prevent leaks under high pressure and temperature cycles.
TIG Welding Ensuring Leak Free Integrity
Each radiator tank and core joint undergoes 100 percent TIG welding in a controlled environment, creating a uniform fusion that resists cracking under repeated heating and cooling cycles. This method produces deeper penetration compared to other welding processes, sealing microscopic gaps and preventing coolant leaks at high pressures common with manual transmission systems. Rigorous air pressure testing inspects every seam for porosity or micro-cracks, ensuring airtight integrity before the unit leaves the factory. Built locally in the United States, the precision welding approach reduces the need for future repairs and gives builders confidence in daily driving or spirited road use.
Aluminum Tube and Fin Core Design for Fast Heat Rejection
The full aluminum tube and fin core is engineered to achieve superior thermal efficiency while maintaining a lightweight profile ideal for LS and LT engine swaps. Coolant travels through closely spaced, narrow tubes that maximize surface area contact with fins, rapidly transferring heat to ambient air passing through the radiator. This design prevents localized hot spots that can lead to detonation or accelerated component wear during towing or performance driving. By optimizing fin density and tube wall thickness, the core sustains consistent operating temperatures under varied loads, promoting engine longevity and stable performance.
Direct Fitment for 1955-1957 TriFive Manual Transmission Installations
Designed to match factory inlet, outlet and mounting locations for Chevy 150, 210, Bel Air and Delray models, this radiator installs without modifications or additional brackets. Installers can reuse original frame rails and support hardware, preserving chassis geometry and reducing installation time. Exact alignment of hose connections and mounting points eliminates interference with steering linkages and fan shroud placements. The precise fit ensures unobstructed coolant flow and airflow, while maintaining the chassis integrity and period-correct appearance throughout the build process.
Coating Options Delivering Corrosion Protection
Choose between a natural bare aluminum finish or a black epoxy coating to suit restoration goals and environmental conditions. The untreated aluminum surface naturally resists oxidation under normal driving, showcasing a bright metallic appearance. The epoxy variant adds a resilient barrier against road salt, moisture and grime in regions with harsh winters or coastal climates. Both finishes simplify cleaning, protect structural integrity and help maintain resale value by preserving core performance and appearance over time.
