LS Swap Radiator for 1990-1996 Chevy Corvette
When installing an LS motor into a 1990-1996 Corvette with a 4L60E or 4L80E automatic transmission, the factory cooling system often falls short under heavy loads. This 1990-1996 Corvette Radiator (Auto Trans) channels coolant through an aluminum core that resists corrosion and copes with sustained heat while matching factory Y-Body mounts for a direct fit. By tuning internal flow passages and fin density, it delivers LS engine compatibility for spirited drives and road trips without risking overheating.
Precision TIG Welding for Leakproof Durability
Every tank and core joint on this radiator is welded using TIG technology, which yields uniform weld beads and ensures deep metal fusion. This method delivers robust joints that resist thermal stress and vibration, preventing coolant leaks under heavy engine loads. By maintaining consistent coolant channels, it avoids hotspots that can degrade performance in powerful LS engines. The result is a dependable cooling solution that endures demanding driving conditions.
Tailored Finish Options for Lasting Corrosion Defense
Choose either the classic bare aluminum finish for an authentic look or the black epoxy coating for enhanced corrosion resistance in harsh environments. The epoxy layer bonds tightly to the core and tanks, creating a barrier that shields against moisture and road debris. Both finishes retain the aluminum's thermal conductivity, so you benefit from efficient heat rejection without extra care. This choice lets builders match aesthetic preferences without compromising performance.
Engineered Flow Design for High-Performance Heat Transfer
The radiator's internal passages and optimized fin density promote uniform coolant flow and maximize surface area contact. By balancing flow resistance with heat exchange requirements, it delivers rapid temperature regulation without overworking the water pump. This flow strategy smooths out temperature spikes during spirited driving or towing, reducing thermal fatigue on engine components. Drivers enjoy consistent operation and peace of mind on extended runs.
Direct Y Body Mount Compatibility for Easy Installation
Designed to fit factory Y Body mounts for 4L60E and 4L80E transmissions, this radiator drops into 1990 to 1996 Corvette chassis without modification. It eliminates the need for bracket fabrication or core support alterations, reducing installation time and effort. Detailed mounting instructions guide you through aligning the unit to the original frame points, ensuring a secure fit and quiet operation. The end result respects the Corvette's original geometry while providing enhanced cooling capacity.
