LS Radiator with Automatic Transmission Fans for 1962-1967 Chevy II/Nova X-Body
When swapping an LS engine into a 1962 to 1967 Chevy II or Nova X-Body with an automatic transmission you need a radiator that holds firm against heat soak at idle and under sustained driving. This 1962 to 1967 Chevy II Radiator (Auto Trans) with Fans features a TIG welded aluminum core paired with dual high capacity electric fans that adjust output as coolant temperature rises to protect both engine and transmission circuits. It mounts directly to factory frame points with no extra brackets and includes all necessary hardware for a straightforward fit that preserves clearance and resists corrosion in tight engine bays.
Precision TIG Welded Aluminum Core for Reliable Heat Transfer
The core and tanks of this radiator are joined with full TIG welding using high-grade aluminum, resulting in seamless and uniform weld beads. This method delivers exceptional resistance to fatigue and cracking, a critical factor when an LS engine generates intense thermal loads. By confining potential leak paths, the precision welding process ensures coolant remains contained under high pressure and repeated heating cycles. The all-aluminum structure also cuts weight above the front suspension, enhancing chassis responsiveness and handling. Fabricated in the USA under strict quality controls, each unit meets stringent standards for structural integrity. The result is a robust assembly that supports steady heat transfer whether idling or running at speed.
Dual Electric Fans Supporting Engine and Transmission Cooling
Equipped with two high capacity electric fans, this system guarantees airflow even when natural wind is minimal or absent. At a standstill or in stop and go traffic, the fans engage to draw ambient air across the core and prevent heat buildup in both engine and transmission circuits. As coolant temperature climbs, fan speed increases in a calibrated manner to protect vital drivetrain components during spirited acceleration or highway cruising. The included plug-and-play wiring harness integrates seamlessly with factory sensors or aftermarket controllers. Installation uses existing frame mounts and hardware, eliminating the need for custom brackets or modifications. This design delivers consistent thermal management under all driving conditions.
Finish Selection Enhancing Durability and Style
Enthusiasts can choose between a polished bare aluminum finish or a protective black epoxy coating, each offering distinct advantages. The uncoated design excels at heat reflection and efficient thermal conduction through its smooth, untarnished surfaces. In contrast, the epoxy layer provides a barrier against road debris, moisture, and oxidation without hindering core efficiency. Both finishes resist pitting and maintain a clean appearance in harsh under-hood environments. This flexibility allows builders to match the radiator finish to their engine bay theme while ensuring reliable cooling performance. Over time, the coatings preserve structural integrity and visual appeal.
