1973-1977 A-Body LS Radiator with Fans for Automatic Transmission (Chevelle, Monte Carlo, El Camino)
When installing an LS engine into a 1973-1977 Chevy A Body such as Chevelle, Monte Carlo or El Camino with an automatic transmission, maintaining consistent coolant flow is vital to protect both engine and transmission from thermal stress. The radiator features a TIG welded aluminum core paired with dual electric fans in factory locations to promote even coolant distribution and prevent hotspots along the core surface. Installation uses original mounting points with no chassis modifications required and preserves stock coolant line routing for accurate fitment. In urban gridlock or highway travel the fan system reacts to temperature changes to sustain stable operating conditions under all driving loads.
Precision TIG Welded Aluminum Core Strength
The radiator core and tanks are joined using 100 percent TIG welding to create a uniform bond without filler material. This method produces a seamless union that resists leaks under repeated temperature changes and maintains pressure integrity throughout the cooling system. Aluminum's natural thermal conductivity works in tandem with the weld quality to reject heat rapidly, while the assembly remains lighter than traditional designs. Every unit undergoes a leak check and pressure test to confirm core durability and coolant containment before it leaves the factory.
Dual Fan Array for Balanced Cooling
A pair of electric fans is installed in the factory mounting locations to ensure uniform airflow across the entire heat exchanger. The fans activate in response to coolant temperature, preventing hotspots during idling or slow traffic and sustaining performance during long highway runs. Their balanced arrangement spreads cooling air evenly over the core and transmission cooler, reducing stress on each component. This on-demand approach conserves electrical power by running only when needed, yet it maintains consistent temperatures in all driving conditions.
Seamless Bolt-on Fit for 1973 to 1977 A Body Vehicles
Designed exclusively for 1973–1977 A-Body Chevelle, Monte Carlo, El Camino and related models, this radiator drops into the stock location without requiring frame modifications or custom brackets. It preserves the original chassis geometry and aligns with the factory coolant lines, which simplifies the installation process and reduces fitment errors. Transmission cooler connections plug in directly, ensuring proper clearances and maintaining handling characteristics. Overall, this direct replacement style minimizes labor time and retains the vehicle's authentic under-hood appearance.
Corrosion Resistance with Bare and Epoxy Finishes
Choose the bare aluminum finish to take advantage of the metal's natural oxidation layer or opt for a black epoxy coating for extra protection against moisture and road debris. The epoxy option forms a continuous barrier over welded joints and core surfaces, guarding against corrosion in harsh driving environments. Both finishes are applied before assembly to ensure complete coverage, including internal passages. This proactive treatment extends service life and keeps the radiator looking factory-clean over years of use.
