LS and LT Radiator for 1959-1964 Chevy Impala Manual Transmission
Installing an LS or LT engine behind the manual transmission of a 1959 to 1964 Impala B Body demands a radiator that can hold coolant temperatures steady under varied driving conditions. This 1959 to 1964 Impala Radiator (Manual Trans) features TIG welded aluminum tanks and core along with factory matched frame mounts to ensure a direct fit without trimming or shims. Balanced fin density and precision routed flow passages deliver efficient heat rejection while resisting corrosion so your classic Impala stays cool whether cruising urban streets or towing on open roads.
Precision TIG Welded Aluminum Construction
The radiator features fully TIG welded high grade aluminum tanks and core, delivering uniform strength across every seam. This welding process creates precise joints that resist pressure and heat cycling, reducing the chance of leaks under extreme conditions. Aluminum's low mass helps the core respond rapidly to temperature changes, while the welded assembly maintains structural integrity even when subjected to vibration or thermal expansion. By eliminating bonding agents and rivets, this construction minimizes corrosion points and ensures coolant circulates freely through the core passages. The result is a robust cooling unit with a reliable service life in demanding driving scenarios.
Optimized Core Flow Design for LS and LT Engines
Engineered with a balanced fin density and carefully routed flow passages, the core layout is tuned to the coolant demands of LS and LT powerplants. Fins are spaced to allow rapid heat transfer while avoiding excessive restriction, so the fluid moves efficiently and sheds heat as it travels. Channels within the core promote even distribution, preventing hot spots that can lead to thermal stress on engine components. Testing under simulated towing and stop-and-go traffic confirmed consistent temperature control, making it suitable for both spirited driving and routine hauling. This precision flow design translates to stable operating conditions and improved engine longevity.
Effortless Installation with Factory Matched Mounts
This radiator aligns with the original frame mount locations of 1959 through 1964 Impala B-Body models, eliminating trimming, shims, or adapter plates during installation. Mount bosses are dimensioned to factory tolerances, ensuring the unit drops in with consistent belt and hose clearances. Technicians benefit from reduced fitting time and fewer alignment checks, which also cuts the risk of misinstallation. The design accommodates manual transmission bellhousing shapes without interference, so no modifications to the tunnel or crossmember are required. In practice, a single installer can complete the swap faster and with greater confidence in fitment.
Durable Bare Aluminum and Epoxy Finishes
You have the choice of a polished bare aluminum surface or a protective black epoxy coat, each applied under controlled conditions for uniform coverage. The untreated finish offers a classic appearance and allows you to monitor any developing patina while reflecting radiant heat away from the engine bay. Alternatively, the epoxy layer forms a resilient barrier against road debris, moisture and chemical exposure, extending the life of the radiator. Both finishes retain their integrity through repeated heating cycles and resist surface wear over time. This dual option ensures you can match the radiator’s look and protective needs to your driving environment.
