1991-1996 Impala/Caprice/Roadmaster LS/LT Swap Radiator with Fans for Manual Trans
When swapping an LS or LT engine into a 1991 to 1996 Chevy Impala, Caprice or Roadmaster manual transmission model, maintaining stable coolant temperatures under load begins with the right radiator assembly. This unit aligns precisely within the B Body frame rails and features a full TIG welded aluminum core for rapid heat rejection. Featuring dual electric fans, airflow kicks in only when coolant heat rises, helping to prevent hotspots and minimizing electrical draw at idle. Mounting tabs match factory locations and clear instructions walk installers through hose routing and fan shroud placement for a straightforward, trim free fit.
Dual Electric Fans Deliver Consistent Cooling Under Load
The system integrates two independent electric fans that activate at the precise coolant temperature threshold, maintaining optimal airflow even when vehicle speed is low. By engaging only when needed, the fans minimize electrical demand and preserve engine power at idle. The shroud is engineered to channel air uniformly across the core, preventing thermal hotspots that can compromise coolant system life. In urban traffic or spirited highway drives, this dynamic response ensures that LS and LT powerplants run within safe temperature bands. The design also replaces bulky mechanical fan assemblies, freeing up under hood space for additional swap components.
Fully TIG Welded Aluminum Core for Durability and Heat Transfer
This radiator features a core and tanks assembled with 100% TIG welding, creating consistent, pore free seams that resist the pressure pulses of a swapped LS or LT engine. Aluminum is chosen for its superior thermal conductivity and reduced mass, enabling the radiator to dissipate heat rapidly as coolant flows through the tubes. The precise tube spacing and fin pattern maximize surface area contact, so heat is transferred efficiently into the passing air currents. This construction yields a lightweight package that stands up to the rigors of daily commuting and performance driving alike. Uniform manufacturing tolerances also simplify installation by aligning reliably with the B Body frame structure.
Coating Options Tailored for Efficiency and Protection
Customers may select either a classic bare aluminum finish or a durable black epoxy coat to suit their preference and driving conditions. The uncoated surface provides direct thermal contact for peak efficiency, while the epoxy variant forms a protective barrier against road chemicals, moisture and airborne contaminants. Both finishes are applied using adhesion methods that prevent flaking or blistering over time. By choosing the right option, installers can balance maximum heat rejection with enhanced resistance to environmental corrosion. This ensures sustained performance over many seasons without sacrificing the radiator's structural integrity.
Factory Style Mounting for Streamlined Installation
Precision welded mounting tabs align to the original B Body frame rails on 1991 to 1996 Impala, Caprice and Roadmaster chassis, eliminating the need for cutting or modification. Comprehensive instructions guide the installer through fan placement, hose routing and torque specifications, reducing the risk of common errors that lead to leaks or misalignment. The direct fit also shortens labor time, allowing mechanics to focus on fine tuning the engine and transmission interface. By replicating factory attachment points, the assembly integrates seamlessly with manual transmission models. This hassle free approach delivers a clean final installation without trimming or custom brackets.
