Radiator for LS and LT Swaps in 1991-1996 Impala/Caprice/Roadmaster B-Body
The 1991-1996 Impala Radiator (Manual Trans) meets the exacting needs of LS and LT engine swaps in 1991 to 1996 Impala, Caprice and Buick Roadmaster B Body models with manual transmissions. Featuring a 100% TIG welded aluminum core and tanks crafted in the USA, it retains all factory mounting bosses and hose port locations so installers can fit it using basic hand tools and stock hardware. Offered in bare aluminum or black epoxy finish, this radiator resists corrosion and sustains stable coolant temperatures under extended operation without fans, delivering dependable cooling and streamlining the installation process.
Precision Construction
The 1991-1996 Impala Radiator designed for manual transmission applications offers exceptional durability through its 100% TIG-Welded, High-Grade Aluminum Tanks & Core. Fully welded seams eliminate weak spots that can arise from joint separation under high coolant pressure. The use of premium aluminum ensures rapid heat transfer and resistance to corrosion without adding undue weight to the front end. Proudly made in the USA, each unit meets stringent quality requirements before it leaves the factory.
Optimized Cooling Performance
Maintaining stable operating temperatures is essential for LS and LT engine packages under both street and track demands. This radiator employs a multi row core layout with precision stamped fins that maximize surface area for heat exchange. Enhanced coolant flow passages reduce turbulence and hot spots, helping to prevent thermal breakdown during extended operation. The result is a consistently lower coolant temperature that promotes reliable power delivery and component longevity.
Seamless Vehicle Integration
Engine swaps and restoration projects benefit from exact fitment to the 1991-1996 Impala chassis. Compatibility with MuscleRods mounts ensures proper engine placement and drivetrain angles, eliminating the need for custom bracket fabrication. The radiator’s inlet and outlet ports are positioned to match factory hose connections, preserving original plumbing paths. Core support brackets align precisely, allowing a bolt-in installation that keeps assembly time to a minimum.
Reliability and Quality Assurance
Every radiator undergoes rigorous pressure testing to verify leak-free performance before shipment. Weld beads and seams receive nondestructive inspection to ensure long service life under demanding conditions. The robust aluminum construction resists fatigue from thermal cycles, offering consistent performance from initial startup through high-load scenarios. Backed by a limited warranty, this radiator delivers proven cooling capability for LS and LT engines in 1991-1996 Impala manual transmission conversions.
