Radiator for LS and LT Engine Swaps in 1991-1996 Impala/Caprice/Roadmaster
When swapping an LS or LT engine into a B-Body Impala the 1991-1996 Impala Radiator (Auto Trans) delivers reliable coolant management for automatic transmissions. Engineered from TIG-welded aluminum tanks and core this unit offers fast heat rejection and resistance to corrosion for sustained operation. Installation is straightforward with a direct fit design that aligns with stock mounting points in Impala Caprice and Roadmaster models within the 1991-1996 range. For builders seeking LS and LT compatibility without extra fabrication this radiator provides the essential cooling performance needed for street or track applications.
Precision TIG-Welded Aluminum Construction
Tanks and core are welded using a process that yields contiguous metal bonds offering superior strength and resistance to leaks. Aluminum's high tensile capacity and low mass ensure the radiator resists distortion under repeated temperature changes. This welding method endures vibration from both daily driving and spirited acceleration. This robust construction guarantees lasting reliability while maintaining a lightweight profile for consistent performance.
Efficient Thermal Management for LS and LT Swaps
A generously sized core combined with an optimized fin pattern accelerates heat transfer from coolant into passing air. This design keeps engine temperatures in check, especially when powering Chevy LS or LT engines at high load. Stable coolant circulation prevents hot spots that can compromise head gaskets or piston rings. The result is predictable cooling performance whether cruising on the highway or pushing the engine on a back road.
Straightforward Installation in 1991 to 1996 B-Body Models
Engineered to match the original mounting points in Impala, Caprice, and Roadmaster models from 1991 to 1996, this radiator requires no cutting or extra brackets. Hose connections and transmission cooler ports align precisely with factory fittings, reducing install time and complexity. Built domestically to meet strict tolerances, it works seamlessly with the stock cooling fan and shroud. Owners gain a hassle free upgrade that preserves the vehicle's stock architecture.
Corrosion Resistance with Dual-Style Finish Options
Choose between classic bare aluminum for a timeless underhood appearance or a black epoxy finish for added surface protection. The epoxy finish seals the core and tanks against road salt, moisture, and debris, while untreated aluminum forms a natural oxide barrier to limit corrosion. Both finishes maintain structural integrity over time and support sustained resale value. This flexibility lets builders match aesthetics without sacrificing durability.
