1964-1967 A-Body Chevelle/El Camino LS and LT Radiator for Auto Trans
The 1964-1967 Chevelle Radiator (Auto Trans) is designed to sustain precise coolant control when fitting an LS or LT engine into a classic Chevelle or El Camino with an automatic transmission. The radiator drops into stock frame brackets without trimming or relocation thanks to factory style mounting tabs and a dedicated transmission cooler inlet. Crafted from 100 percent TIG welded aluminum tanks and core, it rejects heat quickly while resisting corrosion even under continuous street or track driving.
Precision TIG Welded Aluminum Construction
The radiator's tanks and core are joined using 100% TIG welding, producing uniform weld beads that resist cracking under engine vibration. This welding method ensures a fully sealed coolant circuit, eliminating weak points that can lead to leaks or reduced thermal performance. Manufactured in the United States, each unit benefits from rigorous quality control to guarantee consistent strength and longevity. As a result, heat rejection remains stable even during extended runs on the street or track.
Seamless Fitment with Stock Brackets and Transmission Cooler Port
Designed specifically for 1964-1967 Chevelle and El Camino A-Body frames, the radiator drops directly into factory mounting brackets without trimming or modifications. Its built-in transmission cooler inlet accepts automatic fluid lines, maintaining original plumbing paths and reducing potential leak points. This precision fit streamlines the swap process, saving installation time and preserving the structural integrity of the chassis. Integrating the cooler port into the lower tank also helps regulate transmission fluid temperature under heavy loads.
Aluminum Core and Custom Finish Selections
Crafted from high-quality aluminum, the core conducts heat nearly three times faster than steel, allowing coolant temperatures to drop quickly during hard acceleration or climbing grades. The natural corrosion resistance of aluminum helps internal passages remain clear, promoting reliable performance over time. Choose a bare finish to highlight the metal's natural sheen or opt for the black epoxy coating for enhanced surface protection without sacrificing cooling efficiency. Both finishes fend off pitting and oxidation in humid or salted environments while elevating the engine bay's appearance.
