LS Radiator for 1970-1981 Pontiac Firebird

When fitting a modern LS mill in a 1970 through 1981 Pontiac Firebird with an automatic transmission, this radiator delivers the precise cooling capacity needed for sustained performance. Crafted from 100% TIG welded aluminum, it offers corrosion resistance and fast heat rejection to keep engine temperatures under control on every drive. Fully compatible with LS and LT conversions, it installs using stock mounting points and includes all hardware for a straightforward bolt in setup that suits both home garages and professional shops.

Precision TIG Welded Tanks and Core

The 1970-1981 Firebird Radiator features fully TIG welded aluminum tanks and core that deliver a uniform and robust seam, ensuring leak free performance under sustained heat loads. TIG welding creates a precise bond with minimal distortion, preserving the integrity of the core channels and fin pack. This method of fabrication not only enhances strength but also reduces weight compared to traditional soldered designs. The result is a radiator assembly that stands up to cycles of heating and cooling without compromise.

Exceptional Cooling Efficiency and Corrosion Protection

Constructed from premium grade aluminum, this radiator provides fast heat rejection through an optimized fin and tube layout that maximizes both airflow and coolant flow. Aluminum's natural oxide layer shields against corrosion, preserving the core's integrity over time and in varying weather conditions. By maintaining stable engine temperatures, you protect your LS conversion from thermal stress and potential damage. Whether you're cruising through town or tackling steep grades, reliable cooling keeps performance consistent.

Built Locally for Reliable Fit and Long Term Performance

Manufactured in the USA under strict quality standards, this radiator benefits from precise craftsmanship at every stage of production. Local fabrication ensures tight tolerances and a perfect match to 1970 through 1981 Firebird frames, eliminating the need for custom modifications. Durable construction and finish options support a lengthy service life, while its reputation for dependable operation can enhance the resale appeal of your classic F Body restoration.

Direct Bolt In Installation for LS Engine Conversions

This radiator is engineered for a hassle free bolt in installation on Firebird models equipped with an automatic transmission. It uses all factory mounting points and includes the complete hardware kit, so you avoid fabricating brackets or welding. Compatibility with LS engine swaps means professional shops and home garages alike can achieve a precise, reliable fit.
