1963-1972 Chevy Corvette Radiator for LS Engine with Fan
Retrofit projects that drop an LS powerplant into a 1963-1972 Y Body Corvette with manual transmission demand a cooling solution that fits within the factory envelope while maintaining correct hose routing and mounting geometry. The 1963-1972 Corvette pin mount radiator with fan installs directly on stock bosses so aftermarket brackets or frame modifications are not required. Its aluminum core features a dense array of flat tubes and fine fins engineered for swift heat rejection under sustained loads. Combined with a 16 inch axial fan that draws minimal electrical current this design keeps coolant temperatures in check in stop and go traffic or spirited canyon runs.
Aluminum Core Heat Rejection
The radiator's full aluminum construction maximizes thermal conductivity by transferring engine heat rapidly into its dense array of flat tubes and fine cooling fins. This material choice not only accelerates heat rejection under sustained loads but also keeps weight to a minimum, preserving the Corvette's original handling balance. Aluminum resists corrosion and pitting over time, so coolant passages remain clear and efficient even after many service cycles. With this design, drivers enjoy stable operating temperatures during spirited canyon runs or extended highway cruising without risking heat soak.
Efficient Single Fan Design
Equipped with one 16 inch axial fan, the assembly delivers substantial airflow while drawing minimal current from the electrical system. Its slim profile clears alternator brackets and heater hoses, eliminating the need for frame modifications or custom mounting hardware. By maintaining a steady airstream at low amperage, the fan keeps coolant temperatures in check during traffic jams and hill climbs without overloading the charging system. This balance of power draw and performance ensures reliable cooling without compromising battery life or vehicle electronics.
Direct Pin Boss Fitment
This radiator bolts directly to the factory pin bosses used on 1963 to 1972 manual transmission Corvettes, preserving the stock hose routing and mounting geometry. Installers avoid fabricating brackets or altering frame rails, reducing labor time and potential alignment errors. The pin mount interface also dampens vibration, minimizing stress on hoses and fittings to prevent leaks over many miles. With plug and play fitment, enthusiasts spend less time under the hood and more time enjoying their LS-powered classic.
Bare Aluminum and Epoxy Coating Options
Choose a natural bare aluminum finish to showcase the core's metallic sheen and direct heat conduction, or select a black epoxy coating for enhanced protection against moisture and road debris. The epoxy option repels oil and grime, making routine cleaning simpler without affecting cooling efficiency. Both finishes are applied uniformly to maintain structural integrity and weight targets. Coordinating the coating with surrounding engine bay components delivers a cohesive look while ensuring long term corrosion resistance.
