LS and LT Radiator for 1968-1972 A-Body and 1970-1972 Monte Carlo
The 1968 to 1972 A Body and 1970 to 1972 Monte Carlo Radiator (Manual Trans) with Fans tackles the cooling challenge of LS and LT swaps by using a platform specific design that fits factory brackets and firewall clearance. Featuring a TIG welded aluminum core and dual high capacity electric fans, the assembly draws air uniformly across the full surface to prevent heat spikes during stop and go conditions or spirited runs. All mounting points and hose connections align with original factory locations to preserve firewall clearance and eliminate the need for custom brackets or adapter fittings. Built in the USA from corrosion resistant aluminum, it cuts installation time and maintains steady coolant flow.
Precision TIG Welded Aluminum Core Construction
The entire radiator core and end tanks are joined using TIG welding, a method that lays down uniform seams under exact heat control to eliminate gaps and prevent leaks through thermal cycling. Aluminum's high thermal conductivity works hand in hand with the precise welds to transfer heat swiftly from coolant to fins, then to the oncoming air. By avoiding distortion during fabrication, this approach maintains flat fin alignment and ensures durability under repeated engine start up and shut down cycles. The result is a robust heat exchanger tailored to LS and LT engine systems.
Advanced Dual Electric Fan Cooling
This radiator employs two high capacity electric fans that engage automatically once coolant reaches a preset threshold, delivering steady airflow across the full frontal area. Such even distribution avoids hotspots in slow traffic and under aggressive driving loads, preserving optimal engine temperature. These fans run quietly and draw modest electrical input, so alternator demand remains low while cooling remains consistent. Their design also supports fine tuning of activation temperatures and fan speed via standard GM wiring, giving builders control over thermal management.
Exact Fit Factory Mount and Hose Alignment
Engineers designed this radiator to bolt directly into the original 1968 to 1972 A Body and 1970 to 1972 Monte Carlo brackets, preserving firewall clearance without custom adapters. Hose connections follow the stock routing so builders need not fabricate new hard lines or cut brackets. Maintaining the OEM layout prevents interference with steering components, hydraulic lines or transmission linkages when paired with a manual gearbox. This plug and play fit saves installation time and reduces the risk of error during swap projects in home garages or professional shops.
Protective Coating Options for Corrosion Resistance
Owners can choose between untreated bare aluminum, which forms a thin oxide barrier naturally, or a black epoxy coating for enhanced surface protection against moisture and road debris. Both finishes are applied without interfering with heat rejection, so thermal efficiency remains unchanged. The bare option offers minimal weight while relying on aluminum’s inherent resistance to rust, and the epoxy layer adds extra guarding against chemical exposure and impacts. Each finish extends service life and preserves appearance through years of use.
