LS and LT Radiator with Fan for 1958 Chevy B-Body Impala/Bel Air/Delray
The 1958 Impala Radiator (Manual Trans) with Fans is engineered to control coolant temperatures when an LS or LT motor replaces the original drivetrain in a Chevy B-Body. Its 100% TIG welded aluminum tanks and core provide uniform bead profiles that resist stress cracking through repeated thermal cycles. Installation makes use of factory mounting points and original hose routing, eliminating the need for custom brackets or alterations to the frame. Dual electric fans draw air evenly across every fin row, ensuring consistent airflow at idle and during spirited driving without adding bulk to the engine bay.
Precision TIG Welded Aluminum Structure
The radiator's tanks and core are assembled using precision TIG welding to produce consistent bead profiles and minimize porosity at each joint. This process creates weld seams that resist the formation of stress cracks when exposed to repeated heating and cooling cycles. High-quality aluminum offers both excellent thermal conductivity and a favorable strength-to-weight ratio, ensuring that the structure remains sturdy without adding unnecessary mass. Uniform bead geometry also reduces turbulence within the coolant passages, contributing to efficient heat transfer. By combining expert welding techniques with premium materials, the assembly delivers reliable performance under demanding conditions.
Dual Electric Fans for Continuous Airflow Management
Two powerful electric fans are installed to maintain even airflow across every fin row, preventing the formation of hot spots in stop-and-go traffic or slow-speed maneuvers. Their blade design draws air uniformly through the entire core surface, maximizing the rate of heat rejection when engine RPMs are low. Automatic temperature sensors activate the fans precisely when coolant levels approach the ideal threshold, safeguarding against overheating during spirited driving. Integrating the fans directly onto the radiator eliminates the need for bulky shrouds, preserving valuable space in the engine bay. This approach ensures stable operating temperatures for LS and LT powerplants without compromising overall package efficiency.
Simplified Installation with Factory Alignment
The radiator is engineered to align with original mounting points on 1958 Impala, Bel Air, and Delray B-Body frames, allowing a direct fit with no custom brackets or frame modifications. Hose connections match the factory routing for manual transmission setups, ensuring proper belt alignment and leak-free operation from the moment of installation. Wiring for the dual fans utilizes existing harness pathways, reducing clutter and avoiding additional drilling or trimming. This straightforward approach reduces installation time and eliminates guesswork, enabling builders to focus on other aspects of the swap. Clear instructions guide users through each step, making it accessible for both seasoned mechanics and first-time engine swap enthusiasts.
Finish Selection for Corrosion Protection and Visual Appeal
Choose the classic bare aluminum option for a polished, show-quality appearance that highlights the radiator's precision workmanship. Alternatively, the black epoxy finish offers enhanced resistance to moisture, road salts, and grime without impairing heat transfer. Each coating is applied uniformly to preserve the radiator's performance characteristics while providing long-term protection against pitting and surface degradation. The black finish adds a subtle contrast in the engine bay, while bare aluminum reflects engine bay lighting for a bright, open look. Both options ensure that your cooling system remains as attractive as it is functional over years of use.
