1991-1996 B-Body Manual Transmission Radiator for LS and LT Swaps in Impala Caprice Roadmaster
Swapping an LS or LT engine into model years 1991 through 1996 Impala, Caprice or Roadmaster with a manual transmission demands a radiator that aligns exactly with your full size chassis mounting points while managing heavy loads on the highway and track. This 1991-1996 Impala Radiator (Manual Trans) installs without chassis alterations, bolting directly to OEM brackets and fluid lines to save workshop hours and eliminate shroud trimming. Crafted in the USA with a fully TIG welded aluminum core and tanks, the assembly offers superior thermal conductivity and stands up to corrosion and vibration for reliable performance. Its LS and LT compatibility design maintains stable coolant temperatures during extended highway runs or spirited driving so you can concentrate on your swap without cooling worries.
Precision TIG Welded Aluminum Assembly
The radiator features TIG welded joints at every tank connection and core seam, delivering a uniform wall thickness that prevents stress concentrations and leak paths. Precise heat control during welding preserves the original flow geometry of the fins and tubes, ensuring coolant travels smoothly without disruption. This fabrication method produces a robust one-piece structure capable of withstanding repeated thermal cycles and high vibration levels common in full size chassis applications. As a result, the assembly maintains its integrity under sustained loads, providing dependable cooling in highway cruising or spirited driving.
Rapid Heat Rejection with High Quality Aluminum Core
Crafted entirely from premium aluminum, the core maximizes thermal conductivity to transfer heat quickly from the engine coolant to surrounding air. An optimized fin spacing and tube layout promote even coolant distribution and prevent hotspots during heavy towing or long highway runs. Aluminum's low mass also reduces overall system weight, improving vehicle balance and responsiveness. Together, these factors ensure coolant temperatures stay within an ideal range, minimizing the risk of overheating under demanding conditions.
Protective Bare Aluminum or Black Epoxy Finish
Choose the natural bare aluminum variant for unobstructed radiant heat rejection and a classic engine bay appearance that develops a protective patina over time. Alternatively, the black epoxy option applies a uniform barrier against moisture, salt and road debris, safeguarding the metal from corrosion without hindering thermal performance. Both finishes are precisely applied to critical areas, sealing weld seams and core surfaces while maintaining the structural robustness of the assembly. This attention to surface protection extends radiator lifespan and preserves resale value.
Direct OEM Fitment for Manual Transmission B Bodies
Engineered for 1991-1996 Impala, Caprice and Roadmaster models with manual gearboxes, this radiator aligns perfectly with factory brackets and fluid fittings. No trimming of shrouds or chassis modifications are required, so you can secure and plumb the unit using basic hand tools and existing hardware. By matching original mounting points and hose connections, installation time is slashed and the vehicle's serviceability remains intact. This straightforward drop-in design keeps your engine swap project on schedule and professional in appearance.
