LS Radiator with Fans for 1970-1981 Pontiac Firebird Manual Transmission
Swapping an LS mill into a 1970-1981 Pontiac Firebird manual transmission chassis can push the stock cooling system beyond its design and lead to overheating in traffic or spirited driving. Featuring TIG-welded aluminum tanks and a precision-machined core, this radiator pairs with dual electric fans to keep coolant temperatures steady on highway runs and in stop and go traffic. Installation relies on existing factory mounts for a no-weld approach requiring no frame modifications and slides into the Firebird engine bay cleanly.
Precision TIG welded Aluminum Core
The 1970-1981 Firebird Radiator features a precision TIG welded high grade aluminum core and tanks, delivering leak free joints and exceptional strength under pressure. Aluminum is known for its rapid heat conduction and light weight, crucial for an LS engine swap that demands rapid heat rejection without adding excess mass to the front end. TIG welds ensure uniform joins that resist fatigue and vibration, maintaining seal integrity over repeated heat cycles. This construction method also minimises distortion from high heat zones around the welds, preserving the core's flatness and ensuring consistent coolant flow. The result is a radiator built to withstand both daily driving and spirited track sessions.
Dual Electric Fans for Steady Coolant Flow
Equipped with two high output electric fans, this cooling package maintains ideal temperature under all driving conditions. The fans engage as coolant temperature rises, boosting airflow through the core when the vehicle slows or idles in traffic. By actively managing heat rejection, the system prevents the LS engine from creeping into high temp ranges that can stress seals and gaskets. On the highway, the dual fan setup works in tandem to ensure even air distribution, reducing hot spots within the radiator core. This reliable airflow control is especially beneficial during spirited runs or at the track where constant heat management is critical.
Bare Aluminum and Epoxy Coating Options
Buyers can choose between a raw aluminum finish that showcases the material's craftsmanship or a black epoxy coating for additional surface protection. Bare aluminum naturally forms a thin oxide layer that guards against corrosion, while the epoxy finish provides a durable barrier against salt, road chemicals and moisture. This protective layer also preserves a sleek appearance in the engine bay and simplifies cleaning during routine maintenance. Both options are applied in a controlled factory environment, ensuring uniform coverage and adhesion. The choice allows enthusiasts to balance visual style with environmental resistance based on their driving habits and climate.
Factory Mount Installation for Simple Fit
This radiator installs using the Firebird's original mounting points, eliminating the need for frame modifications or aftermarket brackets. With no cutting or welding required, it slides directly into the F-body chassis and secures in minutes, making it ideal for both veteran mechanics and DIY installers. Detailed instructions guide users through the installation process, ensuring alignment with manual transmission shrouds and fan wiring. This straightforward approach preserves the vehicle's structural integrity and reduces labor time by avoiding custom fabrication. As a result, owners gain a performance cooling upgrade without complex assembly steps.
