LS Swap Radiator for 1962-1967 Chevy II/Nova X-Body Auto Transmissions
When tackling an LS engine swap in your 1962 to 1967 Chevy II or Nova X Body with an automatic transmission, the 1962 to 1967 Chevy II Radiator (Auto Trans) makes efficient cooling straightforward from the first moment. Built with full aluminum tanks and core joined by precision TIG welding, it moves heat quickly through a dense fin layout while resisting corrosion under repeated thermal cycles. Mounting to factory frame brackets and linking directly to cooler lines on both 4L60E and 4L80E gearboxes, this radiator cuts installation time and keeps coolant flow steady from the start. Its plug in fit to stock chassis bracket holes means no cutting or trimming on the X Body frame and lets builders move projects forward with minimal fuss.
Precision TIG Welding for Lasting Integrity
The radiator's tanks and seams are fully TIG welded to create consistent, nonporous bonds between aluminum panels. This process fuses metal surfaces at a molecular level and virtually eliminates the risk of microscopic cracks under continuous temperature swings. Engineers chose TIG welding because it produces uniform weld beads with minimal spatter, which in turn reduces turbulence inside coolant channels and helps maintain an even flow rate. By employing this method throughout assembly, the radiator delivers reliable leak-free operation through seasons of spirited drive cycles.
Advanced Aluminum Core Design for Rapid Cooling
Featuring a premium grade aluminum core with a densely packed fin arrangement, this radiator maximizes surface area for efficient heat exchange. Aluminum's innate ability to conduct heat draws excess thermal energy from the LS engine block and releases it into passing air almost instantly. The balance of minimal mass and exceptional conductivity means the cooling system reacts quickly to sudden temperature spikes, whether you're cruising city streets or towing a heavy load. This design ensures your engine stays within optimal operating range, reducing wear and helping preserve power output over time.
Epoxy and Bare Finishes for Corrosion Protection
Buyers can select either the natural aluminum appearance or a durable black epoxy coating to defend against moisture, road salt, and airborne contaminants. The bare alternative allows direct metal-to-air contact for maximum thermal performance with minimal upkeep, while the epoxy option adds a protective layer that blocks oxidation without hindering heat transfer. Coatings are applied in a controlled environment to guarantee even coverage and strong adhesion. This choice of finishes helps the radiator maintain structural integrity and visual appeal throughout many seasons of use.
Direct Fit to 4L60E and 4L80E Transmission Lines
Designed specifically for 1962–1967 Chevy II and Nova X-Body frames, the radiator aligns precisely with factory bracket locations and original fan shroud mounts. Cooler lines for both 4L60E and 4L80E automatic transmissions hook up directly to integrated ports, eliminating the need for adapters or hard-to-source fittings. This plug-and-play approach preserves chassis geometry, reduces the risk of leaks, and cuts installation time to a minimum. For builders focused on a smooth engine-swap experience, this radiator ensures consistent coolant flow and proper transmission fluid temperature from day one.
