1991-1996 B-Body Radiator Designed for LS/LT Swaps

Achieving consistent engine temperatures in your 1991 to 1996 B Body LS or LT swap with automatic transmission relies on the 100% TIG-welded aluminum tanks and core of this radiator, which offers superior thermal efficiency, fast heat rejection, and lasting durability. Built in the USA and tested for precise fit in Impala, Caprice, and Roadmaster applications, its lightweight design resists corrosion and ensures reliable long service life while preserving factory resale value.

LS and LT Radiator for 1991-1996 B-Body (Impala/Caprice/Roadmaster)

Swapping an LS or LT engine into a 1991-1996 B-Body makes the stock cooling system struggle and the 1991-1996 Impala Radiator (Auto Trans) is designed to handle that extra heat at the radiator core. Engineered with a TIG welded aluminum core and tanks it rejects heat quickly and resists corrosion for enduring service. Installation lines up exactly with factory mounting tabs and transmission cooler ports to save install time and maintain the original fan and shroud setup. The broad core and dense fin layout keep coolant temperature stable whether cruising highways or pushing the engine hard.

Precision TIG welded Aluminum Core and Tanks

The radiator's core and tanks are joined using a TIG welding process that fuses the aluminum at a molecular level, eliminating seams where cracks and leaks often occur under repeated thermal cycling. By opting for full aluminum construction, this unit responds rapidly to changes in coolant temperature while resisting the distortions that can arise during hard acceleration or towing. This method also yields a more uniform structure that withstands vibration from everyday driving or spirited throttle work. The result is a dependable heat exchanger that maintains integrity over many seasons of use.

Engineered Cooling Performance for LS and LT Applications

Swapping an LS or LT motor into a 1991–1996 B-Body platform tends to overload the stock cooling gear, but this radiator features a broad core and tightly packed fin arrangement that accelerates heat transfer into passing air. Such a design prevents the formation of hotspots around the cylinder heads and block rails, which can otherwise lead to gasket failures or oil degradation. The increased surface area also keeps coolant temperature within an optimal window whether you are cruising at highway speeds or navigating steep grades. This balanced approach to thermal management supports both daily driving and occasional track use.

Seamless Integration with Original Fan and Shroud Assembly

Every mounting tab and transmission cooler port is positioned to match the factory points on 1991 to 1996 Impala, Caprice, and Roadmaster chassis, so you can reuse the stock fan, shroud, and hoses without trimming or extra brackets. That direct alignment speeds up installation and preserves the underhood airflow pattern engineered by Chevrolet and Buick. Additionally, retaining the original fan assembly reduces the need to recalibrate electrical circuits or control modules. The end result is a clean fit that looks factory installed and performs as intended from the first start.

Corrosion Defense with Bare Aluminum and Epoxy Coating Options

Installers can choose a classic bare aluminum finish that naturally forms an oxide barrier or a black epoxy coating that offers extra resistance to road salts and moisture. The epoxy layer seals the metal surface against airborne contaminants and ensures the radiator retains its appearance even in harsh winter climates. Both finishes leave the core and tanks structurally sound while guarding against corrosion that can undermine cooling efficiency over time. This flexibility allows for a tailored look without sacrificing protection or resale appeal.
