LS Swap Radiator for 1990-1996 Chevy Corvette Auto Trans
When fitting an LS engine into a 1990-1996 Chevy Corvette with an automatic transmission, overheating poses a serious concern. The 1990-1996 Corvette Radiator (Auto Trans) solves this by channeling coolant through a high-grade aluminum core that withstands thermal stress and resists corrosion. It aligns with factory Y Body mounts for 4L60E or 4L80E units, making installation straightforward even for home mechanics. Internal flow passages and fin density have been tuned to ensure LS engine compatibility during extended drives.
Precision TIG Welded Aluminum Construction
Every tank and core joint on this radiator is created using 100% TIG welding, a method prized for producing uniform beads and deep penetration. This approach results in joints that resist vibration fatigue and maintain a watertight seal even under high thermal stress. The meticulous weld quality also contributes to consistent coolant flow paths, preventing hotspots and ensuring reliable operation over thousands of miles. Such precision is especially beneficial when coping with the higher heat output of an LS engine in classic Corvette applications.
Material Composition and Coating Choices
Crafted from high-grade aluminum, this radiator delivers exceptional thermal conductivity while keeping weight to a minimum. You can select a bare aluminum finish for an authentic appearance or upgrade to a black epoxy layer that adds long-lasting corrosion protection in harsh environments. Both finishes preserve the radiator's performance characteristics and require minimal maintenance, helping to keep coolant temperatures in check under prolonged use. This flexibility ensures your cooling setup remains functional and attractive for years to come.
Engineered Cooling Pathways for Optimized Heat Rejection
The internal flow passages and fin density have been tuned to promote efficient coolant distribution across the entire core. By balancing flow resistance with maximum surface area, the radiator achieves rapid heat transfer without creating excessive backpressure on the water pump. This careful engineering ensures that temperature spikes are smoothed out during spirited driving or towing, providing stable engine operation and reducing thermal fatigue on key components. The result is improved reliability and peace of mind on every journey.
Direct Fitment for Y Body Corvette Automatic Transmissions
Designed to align precisely with factory Y Body mounts, this radiator offers a direct fit for 4L60E and 4L80E automatic transmissions in 1990 to 1996 Corvettes. This eliminates the need for tunnel alterations or bracket fabrication, making it ideal for home enthusiasts and professional builders alike. Comprehensive installation instructions guide you through each step, enabling a straightforward upgrade process. You can expect a snug, rattle-free installation that respects the vehicle's original mounting geometry while enhancing cooling capacity.
