1973-1977 A-Body LS Radiator Manual Trans with Fans for Chevelle Monte Carlo El Camino Laguna
Installing an LS engine into a 1973 to 1977 A Body Chevelle, Monte Carlo or El Camino often reveals that the stock radiator cannot keep engine temperatures in check. This 1973 to 1977 A Body LS Radiator (Manual Trans) with Fans features a TIG welded aluminum core and dual electric fans that engage based on coolant temperature to maintain consistent flow and rapidly cool the engine. Direct factory hose connections and OEM mounting points ensure a bolt in fit for Chevelle, Monte Carlo, El Camino and other A Body models. Its corrosion resistant aluminum structure holds up under vibration so coolant circulation remains stable at idle or under load.
Precision TIG Welding for Enhanced Durability
The core and tanks of this radiator are joined using a precise TIG welding process to deliver a uniform bead pattern that withstands repeated thermal cycles and road vibration. By ensuring smooth transitions between aluminum surfaces, the welds maintain consistent wall thickness and uninterrupted coolant flow across the entire fin stack. Aluminum's natural thermal conductivity works in concert with robust joints to transfer heat away from the engine rapidly, preventing hotspots under sustained load. This rigid structure resists distortion during spirited driving and daily use, offering a reliable solution for demanding LS engine swaps.
Dual Fan Control for Efficient Heat Management
This assembly features two electric fans that activate independently based on coolant temperature, providing just the right amount of airflow without drawing excess power. At idle or in stop and go traffic, a single fan runs to keep temperatures in check while preserving charging output, and when the engine sees heavier demands both fans engage for maximum heat rejection. The integrated shroud holds the blades close to the core to ensure even air distribution across every row of fins. Prewired connectors and included mounting hardware simplify the electrical hookup so installers avoid custom brackets or splicing.
Direct Fitment with Factory Hose Connections
Engineers designed this radiator to match original mounting points and hose end locations on 1973-1977 A Body cars, ensuring a seamless swap without trimming frame rails or modifying firewall openings. Standard hose connections line up with stock plumbing, and mounting tabs sit flush against factory brackets to preserve accessory and steering link clearances. Installers can bolt the unit into place and reconnect cooling lines in minutes, then perform routine service tasks such as coolant changes or fan swaps without disassembling unrelated parts. The result is a straightforward installation that maintains underhood packaging and reduces labor time.
Finish Options to Match Engine Bay Style
Customers may select a classic bare aluminum finish or a black epoxy coating for enhanced protection against moisture and road debris. The epoxy bonds tightly to the metal to inhibit corrosion and abrasion, while uncoated surfaces can be refreshed easily with standard cleaners to restore their bright appearance. These choices let builders tailor the radiator to complement engine bay color schemes without losing performance. In either finish, the protective layer ensures sustained heat rejection and long term resilience in harsh underhood environments.
