1963-1972 Chevy Corvette Y-Body LS Pin-Mount Radiator with Fan for Auto Transmission
When tackling an LS engine swap into a 1963 to 1972 Y Body Corvette with an automatic transmission, coolant clearance often poses the biggest obstacle. Designed around a pin-mounted design that drops neatly between the narrow frame rails, this radiator features a slim aluminum core that clears power steering and air conditioning components without trimming or repositioning accessories. Factory bolt points align with 4L60E and 4L80E transmissions and ensure precise fit within the original chassis geometry. The single 16 inch electric fan draws minimal current yet pushes steady airflow at idle to guard against hot spots and overheat scenarios.
Precision Pin Mounting for Y Body Frame Alignment
The radiator's pin mount layout is engineered to slide directly between the narrow rails of a 1963–1972 Corvette Y Body, delivering an exact location that avoids trimming or clearance work. By matching factory bolt holes used on 4L60E and 4L80E automatic transmissions, the assembly sits flush with the original chassis geometry and maintains proper coolant passage angles. This precise fitment clears the steering pump and air conditioning components without modification, preserving accessory function and eliminating guesswork during installation. Secured by the stock mounting points, the radiator resists vibration and shifting, ensuring consistent coolant flow and reliable performance under city driving or highway cruising.
Full Aluminum Construction for Rapid Heat Transfer
Constructed entirely from premium aluminum, the core offers outstanding thermal conductivity that accelerates heat rejection from a potent LS engine package. Aluminum resists corrosion within the coolant passages, preserving flow capacity and minimizing maintenance over time. Its slim profile is crucial for tight engine bays, yet it provides ample fin surface area to dissipate heat quickly under sustained load. Precision welding at key stress points reinforces the tanks and joints, preventing leaks through repeated thermal cycles. With a lightweight design, steering response remains sharp and front end weight is reduced, benefitting handling without compromising cooling capacity.
Efficient Single Fan Cooling at Idle Speeds
This package includes a single 16 inch electric fan chosen for its ability to maintain steady airflow at idle while drawing minimal amperage from the charging system. By avoiding a twin fan layout, electrical load stays low and wiring harness strain is reduced, which is especially important on classic Corvette harnesses with limited capacity. The fan mounts directly to the radiator frame without extra brackets or shrouds, preserving uniform airflow across the entire core face. In heavy stop-and-go traffic or during extended idling, it prevents hot spots and potential boil over conditions, while quiet operation keeps engine bay noise to a minimum.
Durable Bare or Epoxy Coating for Long-Term Protection
Choose between the clean look of natural aluminum or the black epoxy coating that enhances corrosion resistance and matches custom paint schemes. The epoxy bonds tightly to the metal surface, protecting against chips, abrasions, and moisture intrusion that can lead to rust or pitting. Both finishes withstand repeated temperature swings without cracking or peeling, ensuring weld seams and cooling passages remain sealed over many seasons. This finish flexibility allows builders and restorers to tailor the radiator's appearance to their vehicle's style goals without sacrificing performance or durability.
