1970-1981 Pontiac Firebird LS Radiator with Fans for Manual Transmission
When tackling an LS swap in your 1970 to 1981 Firebird manual chassis, this radiator with dual fans addresses overheating from the start. Beyond matching the factory mounting points, it uses a TIG welded aluminum core that excels at moving heat out of the tight F Body engine bay. Fans activate automatically at higher coolant temperatures so airflow remains steady whether you are cruising city streets or pushing on back roads. Installation is straightforward since bolt holes line up with the original cradle and no custom brackets are needed.
Precision TIG Welded Aluminum Core Construction
The radiator's core and tanks are assembled using TIG welding, a method that produces precise, weld-by-weld fusion between high-quality aluminum components. This well-engineered fabrication process results in joints that resist vibration and thermal cycling, preserving the flatness of the core over years of operation. Aluminum's natural thermal conductivity accelerates heat transfer from the coolant into the fins, allowing the LS engine to maintain stable temperatures even under sustained load. Rigorous quality checks on weld integrity and alignment ensure that every seam remains leak free, so you can trust the system to perform in both daily driving and more demanding conditions.
Intelligent Dual Fan Cooling Management System
This radiator comes equipped with two high-output electric fans that activate automatically as coolant temperatures rise, providing consistent airflow through the tight F-Body engine bay. By responding to the thermal load in real time, the system prevents localized hotspots and helps the engine stay within its ideal operating band during city commutes and spirited runs alike. Each fan draws minimal electrical current when engaged, preserving alternator capacity for ignition and other accessories. Even in slow-moving traffic or on an uphill grade, these fans supply enough air to sustain heat rejection, reducing stress on hoses and seals throughout the cooling circuit.
Seamless Bolt-In Fitment for 1970–1981 Firebird Manual Chassis
Engineers designed this radiator to drop directly into the factory cradle of the 1970–1981 Pontiac Firebird manual chassis without requiring custom mounts or frame modifications. All mounting points line up with the original bolt pattern, and included brackets ensure precise alignment with the transmission housing and fan wiring. This direct swap approach cuts installation time and eliminates guesswork, whether you're in a professional shop or tackling the build in your home garage. Detailed instructions guide you through hose routing and fan relay wiring so you can complete the job cleanly and maintain the Firebird's factory-correct appearance.
Customizable Finishes for Enhanced Corrosion Resistance
Choose between a classic bare aluminum look that develops a protective oxide film over time or a black epoxy finish that offers an extra barrier against moisture, road salt, and airborne chemicals. Each coating option undergoes stringent environmental testing to verify adhesion and durability in wet, hot, and cold climates. The epoxy finish is applied in a controlled setting to achieve uniform coverage without hiding weld detail, while the bare surface retains a technical aesthetic and efficient heat dispersal. Selecting the ideal finish helps safeguard the radiator's lifespan and keeps your engine bay looking sharp regardless of driving conditions.
