LS Swap Radiator for 1984-1989 Chevy Corvette Auto and Manual Transmissions
Whether you are tackling an LS engine transplant or refreshing cooling components on a classic C4 Corvette you need reliable thermal management from the first start. This 1984 through 1989 Corvette Radiator (Auto and Manual Trans) is built around a TIG welded aluminum core and dual electric fans that deliver uniform airflow and rapid heat rejection on both street drives and track sessions. Each unit mounts directly to factory chassis points in the Y body frame without custom brackets or frame modifications so hose routing and fan shroud alignment match factory specifications out of the box.
Precision TIG Welded Aluminum Core Strength
The radiator core and tanks utilize TIG welding, a process that fuses high quality aluminum with pinpoint heat control to create exceptionally strong, leak resistant seams. This joinery method ensures each weld can withstand the rapid thermal swings and increased coolant pressure generated by an LS engine without fatigue or failure. Aluminum's high conductivity accelerates heat transfer away from the coolant, improving the rate at which engine temperature drops under load. By pairing precise welds with a lightweight alloy, the assembly avoids added mass that could upset handling balance on the Corvette Y-Body chassis. Built in the USA to strict tolerances, the core delivers lasting integrity through repeated cycles of heating and cooling.
Dual Fan System for Consistent Airflow
This radiator employs two independent electric fans to drive uniform airflow across its entire width, eliminating localized hot spots that can compromise engine performance. Each fan engages via dedicated temperature sensors calibrated to LS engine characteristics, turning on only when needed to maintain optimal coolant temperature. At idle or in congested traffic, the system sustains airflow comparable to highway speeds, preventing heat soak that can lead to detonation or power loss. During spirited runs or track sessions, the fans work in concert to keep coolant temperature stable under high load. The result is reliable thermal management in a variety of driving scenarios without placing undue demand on the vehicle's electrical system.
Finish Options for Enhanced Corrosion Resistance
Choose between a bare aluminum finish or a durable black epoxy coat to match environmental and styling priorities. The raw aluminum variant showcases the alloy’s natural sheen and allows for simple polishing to address surface oxidation over time. The epoxy option applies a complete barrier over weld seams and tank edges to block moisture, road salt, and airborne contaminants that can cause pitting or corrosion. Both finishes are applied prior to final assembly so that every internal passage and external face receives full coverage protection. This attention to finishing detail extends service intervals and safeguards the radiator against harsh climates.
Direct Fit Installation for LS Swap Efficiency
Designed for a seamless drop in on 1984 through 1989 Corvette Y-Body frames, this radiator mounts directly to factory chassis points with no need for custom brackets or frame modification. It retains original hose routing and fan shroud alignment for both automatic and manual transmission setups, ensuring correct clearances on the first attempt. Clear inlet and outlet fittings mirror OEM dimensions and eliminate flare machining or adapter hoses. Professional shops and home builders save hours of fabrication time while avoiding potential fitment issues. The result is a straightforward installation that complements the LS engine's performance without compromise.
