LS Radiator with Fans for 1970-1981 Pontiac Firebird Automatic Transmissions
For F Body Firebird owners swapping an LS into a 1970-1981 model with an automatic transmission, this radiator and fan package is engineered to maintain steady coolant temperatures under both street traffic and track use. It features high grade aluminum construction with TIG welded tanks and core to resist corrosion and stand up to rigorous driving conditions. Dual electric fans are pre installed and calibrated to deliver consistent airflow when engine demand rises. Installation is painless thanks to a fully assembled design that fits factory mounting points without any modifications.
Precision TIG Welded Premium Grade Aluminum
The radiator core and tanks are joined using TIG welding, creating strong, seamless bonds that resist cracking and leaks under extreme driving conditions. Aluminum's inherent light weight and rapid heat dispersion help the engine shed heat more effectively than traditional materials. This fabrication method also minimizes stress points and offers enhanced resistance to corrosion over time. By relying on precision welding, the assembly delivers a service life that outpaces riveted or braised units.
Dual Electric Fans for Consistent Cooling
Equipped with two calibrated electric fans, the system maintains steady coolant temperatures even in stop and go traffic or during track sessions. The fans engage automatically as engine demand rises, supplying high volume airflow exactly when it's needed most. Their location and design ensure uniform distribution across the entire core face, preventing hot spots that can lead to overheating. Integration into the core frame also avoids interference with surrounding engine bay components.
Finish Options for Corrosion Resistance
Select either a bare aluminum finish or a black epoxy coating to suit your build's aesthetic and environmental needs. Both options guard against oxidation and pitting in humid or road salt conditions. The epoxy layer seals microscopic metal pores and blocks contaminants from degrading the core structure. Even under daily exposure to temperature changes and moisture, the protective finish holds firm without peeling or fading.
Factory Fitment for Simple Installation
This fully assembled radiator and fan assembly is tailored to match the stock mounting points on 1970-1981 Pontiac Firebirds with automatic transmissions. No cutting, trimming, or custom brackets are required when swapping an LS engine into your F body. The drop-in design accepts original hardware for a hassle-free installation. Completing the installation is straightforward, allowing you to return to driving with optimal coolant management.
