1991-1996 Impala/Caprice/Roadmaster Radiator with Fans for LS and LT Swaps
Swapping an LS or LT motor into a 1991 to 1996 Impala with a manual transmission often exposes the stock cooling system's limits under sustained load. With a full aluminum core paired to dual high velocity fans, this radiator delivers consistent heat rejection whether you're cruising on the freeway or crawling through traffic. Installation is straightforward thanks to direct-fit mounts and clear instructions that guide placement within the B-Body frame rails. By eliminating hot spots, it keeps coolant temperatures stable for Impala, Caprice and Roadmaster applications.
Advanced Aluminum Core Design for Enhanced Heat Rejection
The full aluminum core is engineered to handle the increased thermal load of LS and LT engine swaps in B-Body platforms. With optimized fin density and tube spacing, it maximizes surface area for rapid heat transfer from coolant to air. Aluminum's inherent light weight reduces front-end mass, improving overall vehicle balance. This design ensures stable coolant temperatures during sustained highway runs and demanding urban traffic conditions.
Integrated Dual High Velocity Fans for Consistent Airflow
Equipped with two electric fans, the radiator maintains steady airflow across the entire core regardless of vehicle speed. Temperature-sensing controls activate the fans at precise thresholds, preventing coolant temperatures from spiking in slow traffic. The custom-fit shroud directs air evenly through every channel, eliminating hot zones that can lead to engine stress. This configuration delivers reliable cooling when passive airflow alone cannot suffice.
Precision TIG Welding for Leak-Proof Durability
All joints between tanks and core tubes are fabricated using TIG welding, a process renowned for its clean, uniform weld beads and minimal porosity. This method yields exceptional resistance to high coolant pressure and vibration, ensuring the radiator remains leak free under extended use. Tighter dimensional tolerances from TIG welding also guarantee a precise fit within factory mounting points, reducing installation adjustments.
Coating Options for Corrosion Protection and Visual Appeal
Choose a natural bare aluminum finish or a rugged black epoxy coating to match your vehicle's style and environmental exposure. The bare finish allows direct heat shedding from the core, while the epoxy layer adds a durable barrier against road salts and moisture. Both finishes adhere to rigorous standards to resist peeling and flaking, preserving both function and appearance over time.
