Radiator for LS and LT Swaps in 1991-1996 B-Body Impala/Caprice/Roadmaster
Keeping engine temperatures in check is critical when installing an LS or LT engine swap into a B-Body Impala from 1991 to 1996 with manual transmission. The 1991-1996 Impala Radiator (Manual Trans) is engineered precisely for that task. It delivers reliable heat rejection through its full aluminum core and tanks while fitting straight into Impala, Caprice and Roadmaster chassis without trimming factory mounts. Offering LS and LT compatibility and corrosion resistance, it ensures consistent cooling under sustained load so your project maintains peak performance.
100% TIG Welded Aluminum Core and Tanks
This radiator is assembled with precise TIG welding at every joint to create a uniform, leak free structure. The controlled welding process minimizes heat distortion and maintains consistent wall thickness, which translates to improved strength under pressure. By eliminating weak points around seams, the design prevents coolant loss and extends the life of the cooling system even under sustained load. Fabricated entirely in the USA, it assures reliable performance from the shop to the track.
High Quality Aluminum for Rapid Heat Rejection
Constructed from high quality aluminum alloy, the core and tanks combine low weight with exceptional thermal conductivity. Aluminum channels heat quickly from the engine coolant to the thin, wide cooling fins, delivering superior heat transfer rates compared to traditional materials. This rapid rejection of excess heat helps maintain stable operating temperatures during spirited driving or heavy towing. The lightweight nature of the assembly also reduces front end mass without sacrificing durability.
Classic Bare Aluminum or Durable Black Epoxy Finish
Choose between a polished bare aluminum surface that maximizes raw heat radiation or a black epoxy coating that adds an extra layer of corrosion protection. The bare option provides a timeless industrial look while ensuring no reduction in thermal efficiency. The epoxy alternative resists moisture and road contaminants, preserving the radiator's appearance and performance over time. Both finishes are applied with precision to cover every corner and edge for uniform coverage.
Direct Fitment for 1991 to 1996 B Body Impala Caprice Roadmaster
Engineered for a straightforward installation into manual transmission models, this radiator mounts directly to factory locations without any trimming or modification. It is fully compatible with LS and LT engine swaps in the 1991-1996 B Body chassis, aligning fluid passages and mount brackets exactly as the original unit. This plug in style fitment reduces the risk of fitment errors and speeds up the swap process. Whether you are updating a project car or restoring a classic cruiser, the exact match to stock dimensions streamlines assembly.
