LS and LT Radiator for 1968-1972 Chevy Nova and 1964-1966 Buick Skylark
Swapping an LS or LT engine into a classic X-Body Nova or Skylark quickly exposes the limits of the stock cooling setup and calls for a dedicated solution. The 1968-1972 Nova & 1964-1966 Skylark Radiator (Manual Trans) pairs precision TIG welded aluminum tanks with a dense multi tube core to channel coolant across a broad surface area and maintain stable temperatures during spirited driving. Mounting pads are CNC machined to factory specs for a bolt-in fit in 1968-72 Chevy Nova and 1964-66 Buick Skylark frames without any cutting or drilling.
Precision CNC Matched Mounting for Direct Fit
The radiator's mounting pads are CNC machined to replicate original GM X Body frame rails, ensuring exact alignment with stock brackets. This precision matching eliminates the need for cutting or drilling and protects the integrity of the vehicle's chassis. By delivering a direct bolt-in fit for 1968–1972 Chevy Nova and 1964–1966 Buick Skylark frames, installation time is reduced and the suspension geometry remains unchanged. The rigid connection helps maintain consistent hood clearance and fan shroud positioning under heavy loads. Owners benefit from a straightforward upgrade that preserves factory mounting points while supporting modern engine cooling demands.
TIG Welded Aluminum Assembly for Enhanced Durability
Each tank and core joint is assembled using TIG welded seams, producing a continuous bond that resists fatigue under repeated thermal expansion. Aluminum's natural corrosion resistance is paired with this robust weld technique to deliver a leak-free cooling system capable of withstanding high pressures and temperature swings. The all-aluminum construction also contributes to a significant reduction in front end mass compared to a factory steel core, improving steering response and overall balance. Weld quality is closely inspected to ensure uniform penetration and eliminate weak spots. This approach provides a long-lasting assembly that holds up to spirited driving and extended highway use.
Dual Finish Options for Longevity and Aesthetic Appeal
Buyers can choose from a classic bare aluminum surface that highlights the material's natural sheen or a black epoxy coat designed to resist road salt and moisture. The polished finish suits show cars or restorations where visual impact under the hood is a priority, while the epoxy option delivers an added barrier against corrosion and debris. Both coatings are applied in controlled conditions to ensure full coverage and uniform thickness across tanks, end caps, and core faces. Over time, the protective black layer helps prevent pitting in harsh environments, and the bare option retains a patina that ages gracefully. These choices allow owners to tailor the radiator's appearance without compromising functional reliability.
Dense Multi Tube Core Design for Efficient Heat Transfer
The multi tube core features tightly spaced coolant channels that maximize surface area for rapid heat rejection. Coolant travels through numerous small passages, exposing more fluid to aluminum walls and enabling consistent temperature control even under high engine loads. This design sustains stable pressure and prevents localized hot spots that can lead to detonation or component stress. Airflow through the core is optimized to match manual transmission applications, ensuring balanced resistance and flow rate. Enthusiasts will notice more faithful temperature regulation during spirited driving or traffic-stop acceleration cycles, resulting in improved engine performance and reliability.
