LS and LT Radiator for 1964-1967 Chevy Chevelle and El Camino A-Body Manual Trans
When fitting an LS or LT engine into a 1964 to 1967 Chevelle or El Camino with a manual transmission the 1964-1967 Chevelle Radiator (Manual Trans) solves the task of routing coolant while matching factory clearances and firewall lines. Featuring a parallel flow core and precision TIG welded aluminum tanks this radiator nests directly into A Body frame rails and integrates manual transmission seal plates to preserve the stock firewall profile without any cutting or custom brackets. Coolant flows through adjacent passages that enhance contact with fins to hold temperatures steady during sustained engine loads or towing duties and the aluminum structure resists corrosion while reducing weight compared with copper units.
Precision TIG Welding for Enhanced Durability
This radiator features premium aluminum tanks and a core joined by precision TIG welding to create fully fused joints that resist fatigue under constant vibration. The technique delivers superior metal fusion compared to brazing or traditional welds, ensuring there are no microscopic voids that can develop into leaks over repeated heat cycles. Every weld is performed and inspected in the USA by skilled craftsmen, resulting in a unit that maintains its structural integrity even when subjected to heavy towing or spirited driving sessions.
Parallel Flow Core Design for Uniform Temperature Control
The parallel flow core channels coolant through multiple adjacent passages to maximize surface contact with the fin array, delivering rapid heat transfer into the airflow. This layout prevents localized hot spots and balances cooling across the full core width, keeping temperatures stable during long highway pulls or when climbing steep grades. By combining this flow pattern with the high conductivity of pure aluminum, the radiator responds quickly to sudden changes in engine load, protecting modern LS and LT powerplants from thermal stress.
A-Body Frame Rail Fit and Manual Transmission Seal Integration
Engineered specifically for 1964–1967 Chevelle and El Camino A-Body chassis, this radiator aligns perfectly with the stock frame rails to provide a true bolt-in installation. It incorporates manual transmission seal plates that maintain the original firewall profile, eliminating the need for cutting or custom brackets. Installers save hours in fabrication time and preserve the underhood appearance, while the factory-style clearance ensures that coolant hoses and shroud mounts line up exactly as intended.
Bare Aluminum or Black Epoxy Finish for Lasting Protection
Builders can choose a classic bare aluminum finish that showcases the natural sheen and relies on aluminum's innate resistance to oxidation in dry conditions. For environments with road salt or high humidity, the black epoxy option offers extra protection against corrosion and stone chips without compromising cooling efficiency. Both finishes bond tightly to the core and tanks, resisting UV exposure and temperature extremes so the radiator maintains its appearance and performance season after season.
