1970-1981 Firebird F-Body Radiator for LS Swaps

Premium grade TIG welded aluminum construction delivers superior thermal efficiency and corrosion resistance for your Manual Trans radiator in 1970-1981 Firebird F-Body LS swaps. Made in the USA with precision craftsmanship, it provides fast heat rejection, accurate fitment and lasting durability while enhancing long term performance and resale value.

LS Radiator for 1970-1981 Pontiac Firebird F-Body Manual Trans

The 1970-1981 Firebird Radiator (Manual Trans) directly addresses the cooling demands of an LS swap in classic Firebird restorations. With precision core dimensions and TIG welding throughout, it provides reliable temperature control even under sustained load. Each radiator is built in the USA to match factory mounting points and maintain correct coolant flow for manual transmission models. Designed for use in F Body Firebirds, this solution helps protect against overheating without complex modifications.

Expert Tig Welding for Reliable Durability

The radiator's tanks and core are welded using precision Tig techniques, resulting in exceptionally clean and robust joints. This method minimizes heat distortion and delivers consistent wall thickness at every weld point, which is critical under the constant temperature cycling of an LS engine. By avoiding filler material inconsistencies and ensuring full penetration, these welds stand up to road vibration and extreme pressure without risk of cracks or leaks. The outcome is a durable assembly that supports long term performance and peace of mind on both street drives and track outings.

Core Design Optimized for LS Engine Heat Rejection

Engineered with exacting core dimensions, this radiator maximizes coolant contact area to dissipate heat quickly from high output LS powerplants. Its tube and fin density is balanced to promote laminar flow and reduce hotspots, ensuring stable temperatures even under sustained load. The layout also maintains correct coolant velocity, preventing air pockets and improving overall system efficiency. This targeted approach to heat management keeps combustion chambers within safe operating ranges and helps extend engine life.

Finish Selection Offering Corrosion Protection

Choose between the natural bare aluminum finish or a black epoxy coating, both selected for their corrosion resistant properties. The untreated aluminum option forms a protective oxide layer that self regenerates after minor scratches, while the epoxy acts as an impermeable barrier against moisture and road salt. Each surface is meticulously prepared to ensure strong adhesion and uniform coverage, delivering lasting protection without compromising thermal transfer. These finishes help maintain a showroom-clean appearance in your engine bay for years.

American Made Construction for Factory Fitment

Manufactured in the USA, this radiator adheres to strict quality control standards and uses authentic mounting points for 1970-1981 Firebird manual transmission models. The direct fit design eliminates the need for custom brackets or trimming, so professional installers and weekend enthusiasts can achieve a precise alignment quickly. Local production also streamlines lead times and supports domestic craftsmanship, contributing to reliable fit, superior finish, and enhanced resale value on classic restorations.

Each unit delivers reliable cooling and precise fitment. To complete your cooling solution consider our 1970-1981 Firebird Radiator (Manual Transmission) with Fans which is the same radiator but with fans.
