LS Swap Radiator for 1984-1989 Chevy Corvette Y-Body
Whether you are fitting an LS powerplant into a Y-Body Corvette for street use or track duty this radiator ensures stable coolant temperatures with either a manual or automatic transmission installed. Packed with two electric fans it sweeps airflow evenly across a TIG welded aluminum core and corrosion resistant tanks that stand up to repeated thermal cycles. Mounting aligns with original chassis points and preserves factory hose routing so no custom brackets or major cutting is required. This USA built drop in radiator resists corrosion and delivers consistent cooling to protect the LS swap during urban drives or high speed circuits.
Precision Aluminum Core Welded with TIG Technology
The radiator's core and tanks are joined using precision TIG welding to create seamless coolant pathways that resist leaks under high pressure and rapid temperature changes of an LS engine. TIG welding fuses aluminum with fine control, producing joints that maintain strength through repeated thermal cycles and road vibration. High-quality aluminum conducts heat more efficiently than alternative materials, accelerating coolant temperature drop when under load. The integrity of these welds ensures that the radiator remains leak-free over years of street driving and spirited track sessions. Built in the USA, this construction reflects rigorous quality standards and long-term durability.
Balanced Airflow from Dual Electric Fans
Two high-flow electric fans draw air evenly across the full width of the radiator core to eliminate hotspots and maintain a consistent coolant temperature. Each fan is governed by engine temperature sensors for precise engagement, delivering ample airflow at idle or low speeds without overloading the electrical system. By distributing air uniformly, the design prevents uneven heat buildup that can stress engine components during stop-and-go traffic or spirited runs on back roads. This balanced approach to airflow helps safeguard the LS powerplant from overheating, whether cruising city streets or pushing hard on a track.
Enduring Corrosion Resistance and Protective Finish Options
Choose between a natural bare aluminum surface or a black epoxy coat to enhance resistance against moisture, road salt, and under-hood chemicals. The bare finish highlights the alloy's metallic sheen and allows for easy upkeep with a light polish, while the epoxy layer offers full coverage over weld seams and tank edges to block corrosion at vulnerable points. Both finishes are applied prior to assembly so that every joint and surface is treated before final welding. This comprehensive process extends the service life of the radiator, preserves its appearance, and minimizes maintenance needs in harsh environments.
Simple Drop In Fitment for 1984 to 1989 Corvette Y Body
This radiator mounts directly to the original chassis points on the Y-Body Corvette, eliminating the need for custom brackets or frame modifications. It retains factory hose routing and fan shroud placement for both automatic and manual transmission setups, making installation straightforward for professional mechanics and weekend enthusiasts alike. OEM-style fittings and clearly marked bolt locations streamline the assembly process, reducing install time and ensuring correct positioning from the first trial fit. The result is reliable cooling performance without the hassle of alteration or fabrication.
