LS and LT Radiator for 1958 Chevy B-Body (Impala/Bel Air/Delray)
Swapping an LS or LT engine into your 1958 Impala B-Body with automatic transmission demands a cooling solution that maintains stable coolant temperatures and protects both motor and gearbox. This radiator features TIG welded aluminum tanks and a high flow core to resist corrosion and shed heat rapidly during spirited driving. Installation matches factory cooling line ports and mounting tabs on Impala, Bel Air and Delray frames to keep modifications to a minimum and return you to the road faster.
Precision TIG Welding for Leak Resistance
The radiator's 100% TIG welded aluminum tanks and core deliver exceptionally smooth joints that stand up to engine vibration and road shock. By maintaining consistent weld quality, the design minimizes the risk of coolant leaks and ensures structural integrity under high pressure. Using premium aluminum throughout keeps overall weight down while providing strength to resist cracking or warping. Manufactured in the USA under strict quality controls, each unit meets rigorous standards for durability and long lasting service in demanding driving conditions.
Aluminum Core Design for Enhanced Thermal Efficiency
Featuring a large aluminum core with dense fin spacing, this radiator maximizes surface area for rapid heat transfer away from the engine block. Aluminum's superior thermal conductivity draws heat out of the coolant faster than traditional materials, helping maintain stable temperatures during spirited driving or towing. This efficient design prevents hotspots that can stress head gaskets and seals, protecting both the LS or LT engine and the automatic transmission. Drivers will appreciate steadier temperature readings under load, which contributes to consistent performance and engine longevity.
Exact Bolt In Fit for 1958 Chevy B Body Autos
Engineered specifically for 1958 Impala, Bel Air, and Delray models with automatic transmission, this radiator installs without cutting or modifying the frame. Inlet and outlet ports align precisely with factory cooling lines, and mounting tabs match original B-Body locations for a true bolt in experience. By eliminating the need for hose adapters or custom brackets, installation time is cut significantly and the risk of fitting errors is reduced. This direct fit approach keeps the engine bay tidy and preserves the classic lines of the vehicle.
Durable Finish Options for Lasting Protection
Choose the classic bare aluminum surface to highlight your engine bay or select the black epoxy coating for enhanced corrosion resistance. The bare finish resists pitting and oxidation naturally, while the epoxy layer adds a protective barrier against road debris and moisture. Both options safeguard the core and tanks against environmental damage, ensuring reliable performance season after season. The black epoxy also conceals minor dings and helps maintain a clean, modern look under the hood.
