Radiator for LS-Powered 1970-1981 Firebird F-Body

Aluminum construction forms the backbone of this radiator, delivering fast heat rejection, corrosion resistance and superior thermal efficiency for 1970-1981 Pontiac Firebird F-Body LS swaps. Made in the USA with precision TIG welding, it ensures precise fitment for manual transmission models and lasting durability that supports reliable operation and boosts resale value.

1970-1981 Pontiac Firebird LS Swap Radiator

When fitting an LS motor into a classic Firebird with a manual gearbox the 1970-1981 Firebird Radiator provides exact factory mounting points and optimized core dimensions. Each unit features full TIG welded aluminum tanks and a dense core built in the USA to sustain coolant velocity under heavy load. This design rejects heat rapidly while resisting corrosion so engine temperatures stay consistent on both street drives and track outings.

Precision TIG Welding Ensures Robust Joint Integrity

The radiator uses precision TIG welding on both tanks and the core to deliver joints that endure thermal cycling from an LS engine. This technique creates clean weld beads with uniform wall thickness across the assembly, reducing stress risers that can spring leaks under pressure. Manual gearbox Firebird owners benefit as the seam quality resists vibration and maintains a sealed coolant circuit even under sustained track use. The result is a radiator that stays leak free and serviceable for years without reinforcement or patch work.

Optimized Core Profile for Efficient Heat Dissipation

This radiator features a dense tube and fin layout tailored to the heat output of LS powerplants in F body Firebirds. The precise core dimensions balance coolant flow velocity with surface area to reject heat rapidly, keeping temperatures stable during spirited driving. Its design minimizes stagnant zones and air lock formation, helping maintain consistent cooling under load. Drivers will notice steadier gauge readings and a reduced risk of overheating on both road and track.

Dual Finish Options for Lasting Corrosion Protection

Choose between natural bare aluminum or a durable black epoxy coating, each selected for its corrosion resistant properties in classic engine bays. Bare aluminum forms a self healing oxide layer that wards off rust, while epoxy offers a uniform barrier against moisture and road oil. Surfaces are meticulously prepared to ensure strong adhesion without sacrificing thermal transfer. Both finishes maintain a clean appearance over time without flaking or peeling.

USA Manufacturing for Precise Fitment and Quality Assurance

Built entirely in the USA, this radiator matches factory mounting points on 1970–1981 Firebird manual transmission models without the need for custom brackets or trimming. Rigorous quality checks ensure each unit meets exact tolerances so coolant routing and hose connections align perfectly. Domestic production also streamlines lead times and provides direct support from the maker. Installers and restorers gain consistent performance and confidence on every classic LS swap project.

To complete your cooling package with the same radiator but with fans choose 1970-1981 Firebird Radiator (Manual Transmission) with Fans. Count on MuscleRods for precise fit and dependable cooling.
