1973-1977 A-Body LS Radiator with Fans for Automatic Transmission
Built for 1973-1977 A-Body LS conversions with an automatic transmission this radiator handles the extra heat generated on both the street and the track. A TIG welded aluminum core and tanks endure repeated heat cycles while resisting corrosion. Dual electric fans provide consistent airflow when speeds drop or traffic snarls. Mounting points match your Chevelle, Monte Carlo, El Camino and other A-Body classics for a no-nonsense installation.
Precision TIG Welded Aluminum Core and Tanks
This radiator features a 100% TIG welded construction, delivering exceptional joint strength and leak resistance across repeated heat cycles. The premium grade aluminum core and tanks excel in rapid heat transfer, ensuring the LS powerplant stays within optimal temperature ranges under both street and track use. By eliminating mechanical fasteners and seals, the one-piece weld layout minimizes weak points, enhancing durability in high-stress conditions. The inherent corrosion resistance of aluminum further extends service life, while the lightweight design contributes to overall vehicle balance and handling.
Optimized Dual Electric Fan Cooling
Equipped with two high-output electric fans, this assembly maintains consistent airflow when vehicle speed slows or idle periods lengthen. Each fan draws air evenly through the core, preventing hot spots that can lead to engine knock or reduced power output. The fans activate via temperature-controlled relays, ensuring cooling only when needed for efficiency. This setup keeps coolant temps steady in heavy traffic or on the strip, safeguarding components and preserving performance under demanding conditions.
Finish Options for Lasting Corrosion Protection
Choose between a classic bare aluminum finish that showcases the natural metal or a black epoxy coating that adds a layer of protection against moisture and road salt. The epoxy option not only resists corrosion but also complements darker engine bays for a more refined appearance. Both finishes are applied with uniform thickness to maintain core efficiency and prevent paint issues over time. This flexibility lets builders prioritize show quality or pure functionality without compromising cooling performance.
Direct Fitment for 1973 to 1977 A Body LS Conversions
Designed specifically for 1973-1977 A Body chassis, this radiator bolts directly into Chevelle, Monte Carlo, El Camino, Buick Regal, Oldsmobile Cutlass, Pontiac Grand Am, Pontiac Grand Prix, and GMC Sprint frames. No specialized brackets or frame modifications are required, making LS engine swaps straightforward and time-efficient. The layout accounts for automatic transmission plumbing, fan shroud clearance, and stock mounting points. This precise fitment reduces installation guesswork and helps maintain factory alignment and handling characteristics.
