LS and LT Engine Swap Radiator for 1958 Chevy B-Body (Impala/Bel Air/Delray)
When an LS or LT engine goes under the hood of a 1958 Chevy Impala, Bel Air or Delray with a manual transmission, heat management becomes critical and the 1973-1974 Nova Radiator (Manual Trans) with Fan answers that call. Crafted from TIG welded aluminum, this radiator uses a dense fin core to draw heat away quickly, keeping coolant and transmission temperatures in check. The unit bolts directly to stock B-Body frame tabs and aligns with factory cooling ports for a clean installation that avoids custom brackets or trimming. At low speeds, the integrated fan kicks in to maintain airflow without extra wiring or relays.
Precision Bolt-On Fit for 1958 Chevy B Body Installations
The 1973-1974 Nova Radiator is engineered to align perfectly with the original frame tabs of a 1958 Chevy Impala, Bel Air or Delray equipped with a manual transmission. By matching factory cooling port locations, this radiator removes the need for custom brackets or trimming and preserves the showroom quality engine bay presentation. Installers benefit from straightforward hose routing that reduces strain on fittings and minimizes the risk of coolant leaks. This precision fit not only speeds up installation time but also maintains full compatibility with existing components for hassle-free service.
Durable All-Aluminum Construction with Expert TIG Welding
Featuring high-quality aluminum tanks and core, this radiator relies on continuous TIG welds to deliver superior joint strength and leak resistance. TIG welding produces smooth, uniform beads that evenly distribute stress and prevent cracks during repeated thermal cycles. The all-aluminum design also offers a significant weight reduction compared to cast iron or mixed-metal alternatives, contributing to improved suspension response and overall vehicle balance. Crafted in the USA, the radiator's robust build quality is designed to withstand vibration and maintain integrity over many seasons.
Dense Fin Core and Integrated Fan for Efficient Heat Transfer
At the heart of this cooling solution lies a dense fin array engineered to maximize surface area for rapid heat rejection from both engine coolant and manual transmission fluid. Close fin spacing ensures even temperature distribution across the core and eliminates hotspots that can degrade fluid performance. When the vehicle is idling or creeping through traffic, the built-in electric fan automatically engages to sustain consistent airflow without adding extra wiring or relays. This synergy of passive and active cooling keeps temperature gauges steady under varied driving conditions.
Bare Aluminum or Black Epoxy Coatings for Protection and Style
Owners can choose a classic bare aluminum finish that showcases the clean TIG welds and period-correct aesthetic or opt for a durable black epoxy coating to guard against moisture, road salt and debris. The epoxy layer offers an additional barrier to corrosion, preserving core integrity in harsh environments, while still allowing straightforward surface inspection during maintenance. Both options simplify cleaning, as debris beads off smooth surfaces, and they enable builders to match the radiator appearance to their restoration or custom design vision.
