LS and LT Swap Radiator for 1959-1964 Chevy Impala B-Body
When installing a modern LS or LT engine behind the automatic transmission in a 1959 through 1964 Chevy Impala B Body chassis, the stock unit struggles to maintain safe coolant temperatures under load. The 1959-1964 Impala Radiator (Auto Trans) solves this by combining 100% TIG welded aluminum tanks and core into a single robust assembly. Its high quality aluminum construction resists corrosion and eases vibration fatigue, while inlet and outlet ports align with factory locations for an exact drop in fit. Available bare aluminum or black epoxy coated and built in the USA, it provides dependable cooling for any LS or LT conversion.
Precision Construction
The 1959-1964 Impala Radiator for automatic transmission applications features 100% TIG-Welded premium aluminum tanks and core that deliver exceptional strength and leak-free performance. TIG welding provides uniform penetration at each joint, eliminating weak points common in conventional soldered designs. By combining a rigid structure with aluminum’s inherent thermal conductivity, this radiator sustains continuous heat exchange under heavy loads, minimizes maintenance needs, and resists corrosion over time.
Engine and Vehicle Compatibility
Engineered specifically for LS and LT engine swaps in 1959-1964 Impala frames, this radiator mounts directly to stock locations without modification. Integration with MuscleRods mounting hardware ensures correct engine alignment and optimized drivetrain angles, preserving steering geometry and preventing undue belt tension. The fitment has been validated against factory chassis dimensions, so installers benefit from a true bolt-in solution that archives reliable coolant flow and maintains desired hood clearance.
Thermal Capacity and Fluid Dynamics
Featuring a dual layered core and full-length end tanks, this unit maximizes coolant volume and flow rate to lower operating temperatures in strenuous driving scenarios. The core’s internal passages are dimensioned to balance pressure drop and heat dissipation, while the spacious top outlet and bottom inlet ports accommodate high-volume cooling circuits. As a result, engine temperature variance is reduced during highway cruising and spirited acceleration, safeguarding internal components against thermal fatigue.
Made in the USA Assurance
Each radiator is manufactured in the USA under stringent quality standards, ensuring traceability from raw-material sourcing through final inspection. Domestic production allows close control of material properties and dimensional tolerances, yielding consistent performance across every unit. Backed by experienced fabricators and certified welding specialists, this radiator represents a commitment to craftsmanship that honors the heritage of classic Impala builds.
