Dual Fan Aluminum Radiator Designed for 1970-1981 Firebird LS

Delivering steady cooling performance in city traffic and on the track, the dual core aluminum radiator pairs efficient heat rejection with dual fans to maintain optimal engine temperatures for your LS swapped F-Body Firebird. Precision TIG welding on each tank and core ensures corrosion resistance, lightweight durability, and a direct bolt in fit that meets factory specifications. Made in the USA to guarantee exact dimensions and long lasting performance.

LS Radiator with Fans for 1970-1981 Pontiac Firebird Auto Trans

If you are installing an LS into your 1970 through 1981 Pontiac Firebird with automatic transmission, this radiator with dual fans ensures coolant flow stays steady under traffic or spirited runs. Built from pure TIG welded aluminum, the core and tanks resist corrosion while shedding heat faster than factory units helping maintain consistent operating temperature under load. Its F Body design matches factory mounting points on Firebird chassis for a bolt in fit and no custom brackets or trimming are required. Whether crawling through city streets or pushing hard at the track, the thermostatically controlled fans engage automatically to keep coolant temperatures stable and protect your LS powerplant.

Precision TIG Welded Aluminum Core Construction

TIG welding joins the core tubes and tanks with pinpoint accuracy to form seamless bonds that withstand the higher heat stress generated by an LS engine. This method minimizes microscopic gaps that can lead to coolant leaks or crack propagation under repeated thermal cycles. Using high quality aluminum not only reduces the radiator weight but also promotes rapid heat transfer out of the coolant. Weld seam geometry is optimized to spread stress evenly, preventing weak points and extending service intervals. As a result, your Firebird benefits from consistent performance and fewer concerns about joint failure in daily driving or track sessions.

Dual Electric Fans for Consistent LS Engine Temperatures

Two high capacity electric fans are fully assembled at the factory and wired to engage automatically when coolant temperature rises above preset levels. Their position ensures that airflow covers the entire core surface to eliminate hotspots that could lead to local boil over and engine damage. Quiet operation and efficient current draw help preserve alternator output for other critical systems during extended idling or spirited runs. The fans respond to the demands of both city traffic and open road throttle, keeping the LS powerplant within optimal temperature ranges at all times. This design delivers peace of mind for drivers who demand reliable cooling under varied conditions.

Bare Aluminum and Black Epoxy Coating for Lasting Corrosion Protection

Choosing between the classic bare aluminum finish and a protective black epoxy coating allows owners to balance aesthetics with environment driven durability. Both finishes seal micro voids in the metal surface and guard against moisture and road contaminants that cause oxidation. The epoxy option adds a robust barrier that resists chipping, abrasion, and pitting when driving in harsh weather or on salted roads. Bare aluminum offers a clean, polished look and still benefits from natural oxide formation that slows corrosion. By protecting the core and tanks, these finishes extend service life and reduce maintenance needs over time.

F Body Fitment for Straightforward Bolt In on 1970 1981 Firebird

This radiator package is engineered specifically for F Body chassis used in Firebirds from 1970 up to 1981 with an automatic transmission. Mounting tabs, inlet and outlet locations, and fan clearances align precisely with original frame rails and front support. No trimming, drilling, or custom brackets are required and existing hardware can be reused to secure the assembly. Pre routed fan connectors and coolant hose fittings match standard LS engine layouts to simplify plumbing. The direct fit design cuts swap time and ensures seamless integration with factory sheetmetal for a clean installation and professional appearance.

Trust the precise fit and lasting corrosion protection of this radiator. For the same radiator but without fans see our 1970-1981 Firebird Radiator (Automatic Transmission).
