LS and LT Radiator with Fans for 1991-1996 B-Body Impala/Caprice/Roadmaster
Swapping an LS or LT powerplant into a 1991-1996 Impala, Caprice, or Roadmaster with a manual transmission often pushes the stock cooling system beyond its design limits and this radiator is engineered to maintain stable coolant temperatures under these demands. Featuring a full aluminum core matched to dual electric fans this unit provides consistent heat rejection whether you are cruising on the highway or crawling through urban traffic. Direct fit mounts align the radiator precisely within factory frame rails and clear instructions guide installation to eliminate hot spots and protect LS and LT swaps from temperature spikes.
Precision TIG Welding and Full Aluminum Core
The core structure of this radiator is crafted entirely from high quality aluminum and assembled using a full TIG welding process that ensures uniform weld beads and virtually no porosity. By choosing TIG welding, each joint between tank and tube is made durable enough to endure high coolant pressure and vibrations that come with powerful LS and LT engines. Aluminum is prized for its ability to conduct heat rapidly while weighing less than traditional copper options, and this allows it to respond swiftly to changes in engine load. The combination of optimized tube spacing and fin arrangement increases surface area contact between coolant and air to accelerate thermal transfer. Technicians will appreciate the consistent build tolerances achieved through this method, which reduces the need for additional adjustments during installation. Overall, the welding and material choice result in a radiator that can handle sustained highway speeds and heavy traffic conditions without performance loss.
Dual Electric Fans Maintaining Engine Temperature
This radiator integrates two custom electric fans that work together to guarantee stable airflow across the entire core whenever engine demands rise. Sensor driven controls activate the fans only when coolant reaches a specified threshold, preventing needless power draw at lower speeds. The shroud is tailored to focus incoming air evenly through every tube row so that no section of the core remains under cooled. In urban areas or on the track where airflow from forward motion is limited, these fans maintain consistent temperatures and prevent heat buildup. This design also reduces stress on the engine and prolongs component life by avoiding spikes in coolant heat. Mechanics will find that wiring the fans into the existing harness is straightforward thanks to the provided connectors and instructions.
Choice of Bare Aluminum or Epoxy Coating
Owners may select between a classic bare aluminum surface or a robust black epoxy coating to suit both aesthetic and environmental needs. The uncoated finish allows the core to shed heat directly into the air with minimal interference, preserving peak thermal performance. The epoxy layer offers a protective barrier against road salts, moisture, and other corrosive elements, which is essential for areas subject to winter weather or coastal air. Both finishes adhere to industrial standards that prevent peeling and ensure appearance over time. This dual option appeals to enthusiasts who value either the raw metallic look or a finish that blends seamlessly with modern engine bays. Whichever form is chosen, the protective qualities are engineered to match the radiator's structural reliability.
Direct Fit Mounts for Streamlined Installation
The design uses direct fit mounting points that align precisely with the B Body frame rails of 1991 to 1996 Impala, Caprice and Roadmaster models fitted with a manual transmission. This alignment ensures the radiator seats correctly without the need for trimming or fabrication, cutting installation time significantly. Clear, step by step instructions guide placement and securement of the radiator and fan assembly, highlighting torque specs and hose connections. By following the diagram, installers can eliminate common hot spots and maintain even coolant paths through the core. The result is a uniform cooling surface that reduces temperature variation across different engine speeds and loads. For shops taking on LS or LT conversions, this direct fit approach boosts efficiency and eliminates guesswork, allowing focus on tuning and performance tasks.
