LS and LT Radiator with Fans for 1968-1972 A-Body and 1970-1972 Monte Carlo
When you drop an LS or LT motor into a 1968-1972 A-Body or 1970-1972 Monte Carlo with a manual gearbox, factory radiators often struggle under increased heat load. This 1968-1972 A-Body and 1970-1972 Monte Carlo Radiator (Manual Trans) with Fans is engineered to manage those higher temperatures through its dual fan design and aluminum core. It mounts to original brackets and preserves factory hose routing for a plug and play fit that keeps firewall clearance intact during installation.
Uniform TIG Welded Aluminum Construction
Every radiator and tank assembly is joined using tungsten inert gas welding to create seamless, pore-free bonds that resist leaks under demanding heat loads. TIG welding's precise heat control produces consistent weld beads without the brittleness found in soldered joints, ensuring the core and end tanks remain fully sealed through repeated thermal cycles. Aluminum's high thermal conductivity speeds heat transfer from coolant into the fin array, while its low weight maintains balanced vehicle handling. This construction translates to a durable heat exchanger that withstands the intense operating conditions of LS and LT engine swaps.
Optimized Dual Fan Cooling Performance
Two high-capacity electric fans engage when coolant temperature reaches a preset threshold, pulling air uniformly across the entire aluminum core. This design prevents temperature spikes during stop and go traffic or steep hill climbs, protecting engine internals from thermal stress. The fans draw minimal current from the charging system, allowing reliable operation without overtaxing electrical components. Quiet in operation yet effective at shedding heat, this arrangement delivers stable engine temperatures in both daily driving and spirited runs.
Factory Mount Design Preserves Firewall Clearance
The radiator drops directly into the original brackets on 1968–1972 A-Body frames and 1970–1972 Monte Carlo chassis without modification. Inlet and outlet ports align with factory hose routing to maintain stock firewall spacing and prevent clearance issues. This plug and play approach simplifies installation, reducing fit-up time for home builders and professional shops alike. By retaining the manufacturer's mounting points, the assembly protects surrounding components and ensures precise alignment for manual transmission setups.
Coating Choice for Corrosion Resistance
Choose a natural bare aluminum finish that develops a self-healing oxide layer over time or opt for a black epoxy coating for enhanced protection against moisture and road debris. Both finishes adhere directly to the aluminum substrate without compromising heat rejection, so cooling performance remains unchanged. The epoxy layer adds chemical and impact resistance, while untreated aluminum offers inherent corrosion defense and maintains minimal weight. Either option preserves radiator integrity and appearance season after season.
