1991-1996 Radiator for LS and LT Swap in Impala/Caprice/Roadmaster
The 1991-1996 Impala Radiator (Manual Trans) with Fans is designed to manage coolant temperatures in LS and LT swaps for Impala Caprice and Roadmaster manual models from 1991 to 1996. Engineered to bolt into the B Body frame rails this assembly features a full aluminum core assembled with 100% TIG welding for consistent pore free seams. Equipped with dual electric fans the system activates airflow only when coolant reaches a set point preventing electrical draw at idle and avoiding thermal hotspots under load. Detailed instructions and factory aligned mounting tabs guide installers through hose routing and fan shroud placement ensuring a trim free fit within the B Body chassis.
Precision Fit within B Body Frame Rails
This radiator is crafted to align precisely with 1991 to 1996 Chevy Impala, Caprice, and Buick Roadmaster manual chassis. Factory style mounting tabs are welded to match the original attachment points on the B Body frame rails, eliminating the need for cutting or custom brackets. Clear instructions guide installers through hose routing and fan shroud placement, ensuring a trim free fit that won't interfere with other swap components. By replicating stock locations, this design reduces labor time and delivers consistent alignment under all operating conditions. The result is a clean final installation that integrates seamlessly into the chassis.
Dual Electric Fans Optimized for LS and LT Cooling
The assembly features two independent electric fans that engage at a calibrated coolant temperature threshold to maintain steady airflow at low vehicle speeds. By activating only when needed, the fans minimize power draw at idle while preventing thermal pockets under load. The shroud channels air evenly across the core to promote uniform heat rejection, replacing bulkier mechanical fan assemblies and freeing up under hood space. In stop and go traffic or sustained highway use, these fans ensure that LS and LT engines run within their ideal temperature range without manual intervention. This dynamic response enhances both daily driveability and track performance.
100% TIG Welded Aluminum Core for Efficient Heat Dispersion
Built with high quality aluminum tubes and fins, the core and tanks are assembled using precise TIG welding to create consistent pore free seams that resist repeated pressure pulses from a swapped LS or LT engine. Aluminum is selected for its excellent thermal conductivity and low mass, allowing rapid heat transfer from the coolant into passing air currents. The fin density and tube spacing are calibrated to maximize surface contact, accelerating heat rejection during hard driving or heavy traffic. This lightweight construction supports both daily commuting and spirited performance use without adding excess weight to the front end. The robust welds also guard against leaks and ensure longevity through many heat cycles.
Versatile Protective Coatings for Enduring Performance
Customers may select a natural bare aluminum finish for peak thermal efficiency or a black epoxy coat to add a protective barrier against moisture, road chemicals, and airborne contaminants. The epoxy layer is applied with adhesion methods that prevent peeling or bubbles over time while still allowing effective heat transfer. Choosing the right finish lets installers balance maximum cooling performance with enhanced corrosion resistance, ensuring the radiator maintains its structural integrity and appearance through changing seasons. Both options demonstrate attention to detail and deliver reliable operation mile after mile.
Built to deliver consistent cooling performance, this radiator ensures reliable operation under the rigors of everyday driving. To complete your swap with the same radiator but without fans see our 1991-1996 Impala Radiator (Manual Transmission).
