LS Radiator for 1990-1996 Chevy Corvette Y-Body Engine Swap
When fitting an LS powerplant into a 1990-1996 Corvette Y-Body, reliable coolant circulation becomes a top priority and this 1984-1989 Corvette Radiator (Auto and Manual Trans) ensures consistent heat rejection across varied driving scenarios. Featuring dual electric fans that activate based on coolant temperature, the assembly keeps flow steady during idle holds in traffic or spirited runs on the track. A fully TIG welded aluminum core mates with factory LS plumbing and mounts directly to chassis points without requiring custom hoses or brackets, and your swap gains corrosion resistance and lasting durability thanks to the choice of a bare or epoxy coated finish.
Temperature Regulated Dual Fan System
The pair of electric fans on this radiator engages independently when coolant reaches specific thresholds, ensuring air moves consistently through the core at slow speeds or during extended idling. By activating one fan before the other, the system balances airflow to each section of the core and prevents localized hotspots near the cylinder heads. This sequencing also eases strain on the engine's water pump, allowing coolant to circulate with less effort and maintaining stable temperatures under demanding city traffic or spirited track conditions. Drivers can focus on performance without concern for overheating in challenging scenarios.
Precision TIG Welded Aluminum Construction
All core walls and tanks are formed from high quality aluminum and joined using TIG welding, creating uniform fusion that resists leaks and fatigue over repeated thermal cycles. TIG welding produces a smooth, deep bead profile that stands up to heat expansion and vibration far better than soldered or brazed joints. With aluminum's superior thermal conductivity, heat moves rapidly from the coolant to the incoming airflow generated by the fans. The lightweight nature of this alloy also contributes to better front axle balance, preserving the Corvette chassis's handling characteristics.
Coating Choices for Corrosion Defense
Owners can opt for the natural bare aluminum finish or select a protective black epoxy surface depending on climate and aesthetic goals. The untreated alloy forms a self-passivating oxide film that slows corrosion in most environments, while the epoxy barrier provides extra resistance against road salts, brake dust, and chemical cleaners. Both finishes are applied without adding bulk, so core efficiency remains uncompromised and heat transfer performance is preserved. This flexibility ensures the radiator will look as intended and remain durable over many seasons of use.
Direct Fitment with Factory-Quality Alignment
Designed for seamless integration into 1990–1996 Corvette applications, this radiator uses the original mounting points and matches LS coolant plumbing without the need for custom brackets or hoses. Transmission cooler fittings align precisely for manual transmission models, eliminating adapter fittings that often introduce potential leak sites. The plug and play installation approach reduces labor time and ensures correct geometry, so coolant flow paths mirror factory specifications. The result is a hassle-free swap that delivers reliable operation from the very first heat cycle.
