1973-1977 A-Body Manual Transmission LS Radiator for Chevelle Monte Carlo El Camino
When retrofitting an LS engine into a 1973-1977 A-Body Chevelle, Monte Carlo or El Camino with a manual transmission, tackling cooling demands without modifications can be a major hurdle. This 1973-1977 A-Body LS Radiator (Manual Trans) is built to drop into existing frame rails and manage modern V8 heat with its 100% TIG welded aluminum tanks and core. Crafted in the USA, it leverages aluminum's natural corrosion resistance to provide steady temperature control whether you're navigating city streets or cruising open highways. With inlet and outlet ports positioned for direct hose alignment, installation remains straightforward and factory sheet metal stays intact.
Precision TIG Welded Aluminum Core
Every joint in this radiator is crafted with 100% TIG welding, which provides superior strength and sealing compared to conventional fusion methods. By delivering concentrated heat and precise control, TIG welding minimizes porosity and ensures the tank-to-core bond can withstand the vibration and thermal cycling of a modern LS engine. This approach virtually eliminates leak paths, so coolant containment remains reliable even under sustained operating pressures. The result is a durable cooling assembly built for dependable service in classic GM platforms.
Aluminum Heat Dissipation for Consistent Performance
Constructed from high-quality aluminum, the radiator core maximizes thermal conductivity to pull heat away from coolant quickly. Aluminum's low mass reduces front-end weight, helping preserve factory chassis balance and steering response. Its natural resistance to rust and electrolysis keeps internal passages clear over many seasons, ensuring uninterrupted coolant flow. Together, these properties maintain stable engine temperatures whether tackling slow traffic or extended highway runs.
Direct Drop-in Fit for 1973 through 1977 A Body Manual Transmissions
This radiator is engineered to slot into the original frame rails of Chevelle, Monte Carlo, El Camino and similar A Body models without any cutting or bracket fabrication. Inlet and outlet ports align precisely with stock hose locations and fan shroud mounts, so installers avoid time-consuming modifications and preserve the vehicle's factory firewall and sheet metal. The direct approach yields a clean installation and reduces the risk of fitment issues common to off-the-shelf cooling upgrades.
Custom Finishes for Protection and Visual Appeal
Choose the raw aluminum look for a period-correct engine bay or opt for the black epoxy coating to add a protective barrier against road salts, moisture and debris. The epoxy layer enhances corrosion resistance while offering a sleek contrast to engine components. Both finish options are applied in the USA under strict quality controls to ensure consistent appearance and long-term durability. This dual-option strategy lets builders tailor their swap for either show-quality detail or rugged daily use.
