1970-1981 Pontiac Firebird LS Swap Radiator for Automatic Transmission
If you are swapping an LS engine into a 1970-1981 F-Body Firebird with an automatic transmission the 1970-1981 Firebird Radiator (AutoTrans) provides the precise cooling capacity needed to maintain stable engine temperatures under load. Crafted from fully TIG welded aluminum this radiator offers fast heat rejection and corrosion resistance for prolonged service life. It installs effortlessly using all factory mounting points and includes complete hardware for a true bolt-in fit in home and professional garages. Consistent performance on street drives or spirited backroad runs depends on reliable coolant flow and this design ensures just that.
Precision Fabrication with TIG Welded Aluminum
The radiator uses fully TIG welded aluminum tanks and core to create a uniform seam that resists leaks and warping under extreme temperature cycles. TIG welding delivers a precise bond that preserves the integrity of coolant passages and fin packs, reducing the risk of stress cracks. This fabrication method also trims weight compared to soldered alternatives, contributing to improved vehicle balance and lively throttle response. Solid welds ensure lasting durability even when pushing a modern LS engine to its limits.
Engineered Cooling Efficiency and Corrosion Protection
Premium grade aluminum and an optimized fin and tube configuration ensure rapid heat rejection for stable engine temperatures during both highway driving and spirited backroad runs. The natural oxide layer on aluminum provides inherent corrosion resistance, safeguarding the core against pitting and degradation over time. By maintaining consistent coolant flow and temperature control, this radiator helps prevent thermal stress to internal engine components. You can rely on dependable performance whether towing, cruising, or racing.
Custom Finish Options for Durability and Visual Appeal
Choose between a classic bare aluminum finish that develops a protective oxide barrier or a sleek black epoxy coating for enhanced corrosion resistance and show quality styling. The smooth epoxy layer offers added protection against road debris and environmental contaminants while complementing modern engine bay color schemes. Finishing at the factory also simplifies cleanup and maintenance, allowing you to keep your conversion looking sharp with minimal effort.
Seamless Bolt in Fitment for Automatic Transmission Swaps
Engineered specifically for 1970 to 1981 Pontiac Firebird frames with automatic transmissions, this radiator installs using all factory mounting points and includes a complete hardware packet for a true bolt in process. Clear instructions guide you through each step to eliminate fabrication work or bracket welding. The direct fit design not only speeds up installation but also preserves original chassis geometry for proper coolant line alignment. Whether you're working in a home garage or a professional shop, this radiator streamlines your LS swap project.
