Radiator for LS and LT Swaps in 1968-1972 Chevy Nova and 1964-1966 Buick Skylark
When fitting an LS or LT engine into a 1968-1972 Chevy Nova or 1964-1966 Buick Skylark with an automatic transmission, selecting the right cooling solution is critical for reliable temperature control and engine longevity. Built with a TIG welded aluminum core and tanks, this radiator resists corrosion while delivering consistent coolant flow under sustained high load. Inlet and outlet ports match factory transmission lines to simplify plumbing and maintain correct clearances around the fan shroud in the classic X Body chassis. Its efficient fin arrangement and lean nose weight help preserve front end balance without compromising heat rejection during spirited driving or towing.
Precision TIG Welding for Leak Proof Durability
Every weld seam undergoes TIG welding to yield a strong bond that resists vibration and pressure cycles typical of LS and LT engine use. The process produces smooth joints free of voids, eliminating weak points that can lead to coolant loss. Tanks and core components are fabricated from matching aluminum alloy, ensuring consistent metallurgical properties at each joint. This method maintains structural integrity through repeated temperature swings and aggressive driving conditions. As a result, builders gain a coolant system backbone that minimizes maintenance and delivers dependable service under load.
Aluminum Core for Rapid Heat Transfer and Chassis Balance
The radiator core relies on high quality aluminum chosen for its exceptional thermal conductivity, instantly moving heat from coolant to air. A dense array of parallel tubes and fins maximizes surface area while preserving unrestricted airflow under the classic X Body nose. Rapid heat rejection keeps engine temperatures stable during towing, track runs, or extended highway travel. The lightweight design also reduces front end mass, helping preserve original steering feel and suspension balance in the Nova and Skylark chassis. Aluminum's resistance to warping under stress ensures consistent performance mile after mile.
Coating Options to Match Style and Shield Against Corrosion
Finishes are offered in either a natural aluminum sheen or a durable black epoxy that combines aesthetic appeal with surface protection. The epoxy is applied in a controlled environment to form a uniform barrier against road chemicals, salt spray, and moisture. A bare aluminum surface highlights material grain and will develop a unique patina over time, while the coated option introduces a subtle contrast that complements modern restorations. Both treatments extend service life in coastal or winter climates by preventing surface corrosion. This flexibility lets owners choose an appearance that fits their build without sacrificing long term durability.
Factory Bolt In Fitment for Streamlined Installation
This radiator is engineered to bolt directly into the frame rails of 1968 to 1972 Chevy Nova and 1964 to 1966 Buick Skylark models equipped with automatic transmissions. Inlet and outlet ports are precisely located to match factory transmission lines, reducing hose routing complexity and eliminating the need for special adapters. No additional mounting brackets or core support modifications are required to maintain proper clearance around the fan shroud. Installers save hours of labor and achieve a clean, factory faithful engine bay layout. The precise fitment approach supports repeatable swap results for both professional shops and home enthusiasts.
