1973-1977 A-Body LS Radiator with Fans for Manual Transmission Swaps
For enthusiasts installing an LS engine into a 1973-1977 A-Body with a manual transmission, consistent coolant flow under both stop and go city use and spirited runs is essential, and the 1973-1977 A-Body LS Radiator (Manual Trans) with Fans is engineered to address this by maintaining stable engine temperatures. Each unit features a TIG welded aluminum core that resists cracking and sheds heat rapidly, while factory hose connections and mounting points ensure a true bolt in installation on Chevelle, Monte Carlo, El Camino and other A-Body platforms. A pair of dual electric fans controlled by a temperature sensor engages airflow only when needed, cutting electrical draw and preventing heat soak without wiring modifications.
Precision TIG Welding for Core Integrity
The radiator's tanks and core are crafted from high grade aluminum and joined using precision TIG welding to create deep, uniform weld beads. This process resists cracking from vibration and repeated heat cycles, preserving the assembly's flatness and ensuring uninterrupted coolant flow. Aluminum's natural thermal conductivity accelerates heat rejection, while the robust welds maintain structural integrity under demanding conditions. The combination of a lightweight material and durable joints delivers consistent performance on city streets and at the track.
Dual Electric Fans with Sensor Driven Operation
A pair of electric fans mounted to a custom shroud provides airflow independent of engine speed, eliminating heat soak during idle or crawl traffic. A coolant temperature sensor activates the fans only when needed, which reduces electrical draw and helps extend motor life. The balanced fan arrangement ensures even cooling across the entire core surface for uniform temperature control. Prewired connections and mounting hardware enable a true plug and play installation without the need for additional relays or switches.
True Bolt In Fitment for 1973 to 1977 A Body
Engineered specifically for 1973–1977 GM A Body chassis, this radiator uses factory hose connections and original mounting points for a seamless integration. There is no need for trimming, custom brackets, or clearance modifications, preserving space for steering linkages and underhood accessories. Installers benefit from reduced mock up time and a straightforward swap that aligns perfectly with manual transmission systems. Accurate underhood geometry also makes routine maintenance and future upgrades quick and hassle free.
Protective Finishes in Bare Aluminum or Black Epoxy
Customers can choose a polished bare aluminum surface that buffs to a mirror like shine or a black epoxy coating that adds a durable barrier against road moisture and debris. The epoxy layer resists chipping and abrasion, safeguarding critical areas from corrosion, while the polished finish highlights the radiator's clean lines and can be refreshed with minimal effort. Both finishes withstand repeated temperature cycles without peeling or fading, ensuring the engine bay looks as sharp as it functions.
