1963-1972 Chevy Corvette LS Swap Pin-Mount Radiator with Fan
When you retrofit LS power into a 1963-1972 Y-Body Corvette with a manual transmission, underhood heat and confined space demands a cooling solution built to match the original mounting points. This pin-mount aluminum radiator with its single 16 inch fan bolts directly to factory bosses to maintain correct hose routing while clearing alternator brackets and heater hoses without extra brackets. With a dense network of flat tubes and fine fins that draw heat away rapidly and a fan motor that draws minimal current to keep coolant temperatures in check during stop and go traffic or spirited driving, it delivers a reliable setup for LS conversions in classic Corvettes.
Aluminum Core Thermal Performance
Crafted entirely from high quality aluminum, the core and tanks deliver exceptional thermal conductivity that rapidly transfers engine heat into the dense network of flat tubes and fine cooling fins. This design maximizes surface area contact with coolant, enabling faster heat rejection under sustained loads and reducing the risk of overheating during spirited driving. The lightweight construction contributes to the Corvette's original weight balance for predictable handling, while aluminum's inherent corrosion resistance helps maintain peak efficiency over time. Maintenance intervals can be extended thanks to the material's durability and resistance to pitting in demanding road conditions.
Efficient Single Fan Airflow
The single 16 inch fan is driven by a high performance motor engineered to move a large volume of air while drawing minimal current from the charging system. Its slim profile creates vital clearance around alternator brackets and heater hoses, simplifying installation in the confined Y Body engine bay. By delivering consistent airflow at low electrical load, it keeps coolant temperatures stable in congested traffic or hill climbs without overtaxing the alternator. This balance of airflow and amperage demand ensures reliable cooling without compromising battery life or wiring integrity.
Precision Pin Boss Mounting
This radiator bolts directly to the factory pin bosses used on 1963 to 1972 Corvette manual transmission models, preserving the original hose routing and mounting geometry. By matching stock connection points, installers avoid fabrication of custom brackets and the need to alter frame rails or core support structures. The plug and play fitment reduces installation time and minimizes the potential for misalignment that can cause hose abrasion or coolant leaks. A direct pin mount attachment also dampens vibration, contributing to long term reliability and leak-free performance.
Protective Coating Choices
Buyers may select a classic bare aluminum finish for an understated metallic sheen or opt for the black epoxy coating to add a tough barrier against moisture, road debris and corrosion. The uncoated surface offers direct heat conduction while showcasing the core's natural luster, whereas the epoxy alternative repels oil and grime to simplify cleaning during routine service. Both finishes are applied with precision to maintain the radiator's lightweight profile and structural integrity. Coordinating the coating with other engine bay components provides a cohesive appearance without affecting cooling efficiency.
