LS and LT Radiator for 1964-1967 A-Body Chevy Chevelle and El Camino Auto Trans
Fitting an LS or LT engine into your 1964 through 1967 A-Body Chevelle or El Camino with an automatic transmission demands a radiator designed to keep temperatures in check. Constructed from 100 percent TIG welded aluminum tanks and core, this radiator delivers efficient heat rejection and resists corrosion under sustained driving conditions. Designed with factory style mounting tabs and a dedicated transmission cooler inlet, it locks into existing frame brackets and plumbing, making LS and LT compatibility a straightforward part of your swap project.
Precision TIG Welding and Core Integrity
This radiator employs 100% TIG welding to fuse the tanks and core into a single, leak-proof assembly. TIG welds create uniform, narrow beads that enhance joint strength and resist cracking under vibration. By eliminating weak points common in mixed-process welds, the coolant pathways remain unobstructed and reliable even under sustained high temperatures. The result is a durable core structure that maintains consistent performance throughout every drive.
Aluminum Thermal Conductivity for Fast Heat Rejection
High-quality aluminum is chosen for its superior ability to transfer engine heat into the air quickly. Compared to steel, aluminum offers nearly three times the thermal conductivity, accelerating coolant temperature drops during hard acceleration or steep inclines. Its lightweight nature also reduces stress on radiator mounting points and contributes to balanced front-end weight distribution. Natural corrosion resistance further ensures that internal passages stay clear, preserving cooling efficiency over many seasons.
OEM Style Mounting with Transmission Cooler Integration
Factory-style mounting tabs align precisely with the frame brackets on 1964-1967 Chevy Chevelle and El Camino models, allowing for a drop-in fit without modification. A dedicated transmission cooler inlet in the lower tank accepts automatic transmission fluid lines directly, maintaining optimum fluid temperature under load. This integrated approach preserves stock plumbing geometry, streamlines installation, and minimizes potential leak points. Owners can complete the swap with confidence that both engine and transmission cooling are handled efficiently.
Finish Options for Protection and Presentation
Choose between a bare aluminum finish that showcases the metal's natural sheen or a black epoxy coating for enhanced corrosion resistance and a modern look. The epoxy layer adheres tightly without sacrificing thermal transfer, ensuring that cooling performance remains uncompromised. Both finishes resist pitting and oxidation, extending service life in humid or road-salt environments. Beyond functionality, each option adds a refined visual touch to the engine bay of your classic A-body restoration.
