1965-1970 Chevy Impala LS Swap Radiator
Adding a high output LS engine swap to your 1965 to 1970 Impala demands reliable cooling and precise fitment and this radiator delivers just that. Designed specifically for automatic transmission layouts in the B-Body chassis, it features notches that clear the power steering box for a straightforward installation. Every core is built from premium aluminum for fast heat rejection under increased torque and horsepower loads. Its factory style profile preserves the classic lines of your Impala while taming modern power levels.
Precision Fitment Tailored for LS Swaps in the B-Body Impala
Installing a modern LS powerplant into a 1965-1970 Impala often requires custom radiator modifications to clear steering components and maintain factory rail alignment. This radiator arrives pre-notched at the lower corners to clear the automatic transmission power steering box, ensuring the system fits exactly within the B-Body chassis mounting points. By holding tight manufacturing tolerances, it removes the need for cutting or shimming during installation, delivering a professional result with minimal effort. Even under the torque loads of an LS swap, this design prevents interference with the frame while preserving your vehicle's original structure and appearance.
High-Performance Aluminum Core for Rapid Heat Rejection
Constructed entirely from premium aluminum, this radiator leverages the metal's high thermal conductivity to pull heat away from coolant faster than traditional brass and copper units. The low overall weight reduces front-end mass, while the optimized fin and tube layout accelerates coolant flow to combat the increased heat output of a high-performance LS engine. On city streets or long highway drives, you'll see more stable operating temperatures and resistance to heat soak during heavy towing or spirited runs. Consistent engine cooling extends component life and sustains peak power without compromise.
Dual Finish Choices for Corrosion Resistance and Classic Appeal
Choose between a classic bare aluminum surface or a durable black epoxy coating to suit both aesthetic and longevity goals. The bare finish offers a period-correct look that can be hand-polished or left to age gracefully, while the epoxy layer adds a protective barrier against road salts, moisture, and engine bay chemicals. Each finish is applied under strict quality control to ensure uniform coverage and adhesion, standing up to vibration and temperature cycles. Beyond protection, these options allow you to maintain an authentic restoration theme or introduce a modern visual accent in your engine compartment.
