LS and LT Swap Radiator for 1991-1996 Chevy B-Body Impala Caprice Roadmaster
When installing an LS or LT powerplant into a 1991 through 1996 Chevrolet Impala Caprice or Buick Roadmaster manual chassis proper heat control is made as simple as a bolt in procedure with the 1991-1996 Impala Radiator (Manual Trans) with Fans that mounts directly to B Body frame rails. Constructed from aluminum with tanks and core joined by 100% TIG welded seams this radiator resists leaks while promoting efficient heat transfer across its fin array. Two performance fans actuate at a calibrated coolant threshold to limit idle draw and prevent hot spots under load. Available with a bare aluminum or durable black epoxy finish this USA built assembly aligns factory hose ports and mounting tabs for a trim final installation you can rely on.
Product Overview
The 1991-1996 Impala Radiator for manual transmission applications is purpose built to support LS and LT engine swaps while delivering dependable cooling under all driving conditions. Dual high performance fans are preinstalled to provide immediate airflow and rapid heat rejection during hard acceleration or slow speed traffic. Precision engineering incorporates fully TIG welded tanks and core for superior strength and resistance to leaks over time. Every unit is made in the USA and subjected to strict quality inspections to guarantee consistent fit and function. The design respects the factory engine bay layout so it installs without interference to service access or exhaust routing.
Construction and Cooling Performance
Central to this radiator is a flat tube core that maximizes coolant contact area and encourages uniform temperature distribution. The dual fan assembly is wired through a standalone harness with adjustable relays, allowing builders to choose manual on off control or automatic activation via a temperature switch. Fully TIG welded joints employ an inert gas shield to create pure metal bonds free of microscopic flaws, an important factor when components repeatedly expand and contract under thermal cycling. High grade aluminum tanks are formed to uniform thickness to resist bulging under pressure and maintain consistent coolant flow. In testing this configuration reduced coolant temperatures by up to 15 percent compared to the original equipment unit, enhancing engine longevity and preventing hot spots in heavy traffic or towing scenarios.
Compatibility and Integration
This radiator is tailored specifically for 1991 through 1996 Impala bodies equipped with manual transmissions and LS or LT V engines. It aligns precisely with MuscleRods mounting pads, ensuring correct engine positioning and optimal drivetrain angles that protect couplings and U joints from added stress. No cutting or filler panel trimming is necessary, as the package includes all brackets and hardware needed for a bolt in installation that maintains factory appearance. Detailed instructions guide installers through each step, from core support bolt torquing to fan shroud alignment. By choosing this radiator, restorers and performance builders gain an upgrade in thermal management without sacrificing chassis integrity or service convenience.
