LS Swap Radiator with Fans for 1970-1981 Pontiac Firebird
When installing an LS engine into a 1970-1981 Firebird F-Body with a manual transmission, the stock cooling setup often struggles in heavy traffic or spirited driving. Featuring a TIG welded aluminum core and twin electric fans, this radiator keeps coolant temperatures steady on highway cruising and in city driving. Installation relies on the factory mounting points in the F-Body chassis, requiring no frame modifications or special brackets for a fast, clean fit.
Precision TIG welded aluminum construction
This radiator features a fully TIG welded high quality aluminum core and tanks for exceptional strength under pressure and leak free performance. Aluminum's rapid heat conduction and light weight are ideal for an LS engine swap that demands fast heat rejection without adding excess mass to the front end. TIG welding produces uniform joins that resist vibration and fatigue over repeated thermal cycles, preserving seal integrity and core flatness. Manufactured in the USA, the construction supports reliable fit and finish for both daily driving and spirited use.
High output dual electric fan operation
Equipped with two high output electric fans, this system actively manages airflow to maintain steady coolant temperatures in stop and go traffic as well as on highway runs. The fans engage automatically as coolant temperature rises, boosting air movement through the core when engine load increases or vehicle speed drops. By distributing airflow evenly across the core, the dual setup prevents hotspots and reduces stress on seals and gaskets. This precise thermal management is especially beneficial during track sessions or spirited driving where consistent cooling is critical.
Classic bare aluminum or black epoxy protection
Choose between a raw aluminum finish that naturally forms a protective oxide layer and a black epoxy coating that provides an extra barrier against road chemicals and moisture. The epoxy option enhances corrosion resistance without hiding the radiator's sleek lines, while the bare finish highlights the craftsmanship of the TIG welds. Both coatings are applied under controlled conditions to ensure uniform coverage and adhesion. This flexibility lets owners balance visual style with environmental durability based on local driving conditions.
Factory mounting for seamless installation
Designed to use the original Firebird mounting points, this radiator installs without frame modifications, special brackets, or welding. It slides into the engine bay on a manual transmission chassis and secures in minutes, reducing labor time and the need for custom fabrication. Detailed instructions cover alignment with transmission shrouds and fan wiring, making the process straightforward for both professional shops and DIY enthusiasts. The result is a clean, reliable fit that preserves the vehicle’s structural integrity.
