LS and LT Radiator with Fans for 1991-1996 Chevy Impala Caprice Roadmaster
When installing an LS or LT engine in a 1991 to 1996 Impala, Caprice, or Roadmaster with a manual transmission, keeping coolant temperatures stable under varying loads becomes critical, and this radiator with fans is engineered to meet that demand. Featuring a full TIG welded aluminum core paired with dual electric fans, it delivers consistent heat rejection whether carving city streets or cruising on the highway. Direct fit mounts align this assembly precisely within the B Body frame rails to eliminate trimming, and clear instructions guide secure installation. Built in the USA to resist corrosion while shedding heat rapidly, this radiator safeguards your swap from dangerous temperature spikes.
Efficient Cooling from Dual Electric Fans
This radiator assembly features two dedicated electric fans that activate precisely when engine heat rises, ensuring consistent airflow through the core even at low road speed. By cycling on only at the specified coolant threshold, these fans avoid unnecessary power draw and permit quieter idling. The fan shroud directs air evenly across every tube and fin, preventing uneven cooling and hot spots that can stress an LS or LT engine under severe conditions. In urban driving and on winding back roads, this system keeps temperatures stable without the need for bulky mechanical fan assemblies.
Precision TIG Welding Meets Full Aluminum Core
The core and tanks are assembled entirely with TIG welding, producing uniform, porosity free seams that resist the pressure and vibration generated by swapped LS and LT powerplants. Aluminum is selected for its exceptional heat conductivity and low mass, allowing the radiator to respond rapidly to changes in engine load. Optimized tube spacing and fin density maximize surface area contact between coolant and passing air, accelerating heat rejection. This construction method also delivers consistent manufacturing tolerances so installers experience minimal fit adjustment during swap projects.
Coating Options for Enhanced Corrosion Resistance
Customers can choose between a bare aluminum finish or a protective black epoxy coating, both designed to complement the raw performance of the core while addressing environmental challenges. The uncoated surface offers direct thermal transfer for peak efficiency, while the epoxy barrier protects against road salts, moisture and other corrosive elements that develop over time. Each option meets stringent adhesion standards to prevent peeling and degradation, ensuring the radiator retains both its appearance and functionality through harsh seasons.
Direct Fit Mounting for Hassle Free Installation
Engineers aligned mounting tabs to the factory B-Body frame rails for a precise, no-trim fit on 1991–1996 Impala, Caprice and Roadmaster models with manual transmissions. Clear, step by step instructions guide the secure placement of both the radiator and fan assembly, including torque specifications and hose routing. This approach eliminates guesswork, reduces install time and avoids common hot spots that occur with ill-fitting aftermarket units. The result is a streamlined installation process that lets technicians focus on tuning rather than fabrication.
