1965-1970 Chevy Impala LS Swap Radiator with Fans
When installing an LS engine into a 1965-1970 Chevy Impala, space around the power steering box and efficient coolant flow rank among the toughest obstacles; this radiator addresses both with an aluminum core contoured to the B Body frame. Its notched design aligns with factory mount points, letting the assembly drop in without trimming or relocating components. Paired with dual electric fans that respond to coolant temperature, it delivers steady air movement in traffic or spirited driving. Matching original fixings and shedding front end weight, the unit helps maintain steering geometry and handling balance. Constructed from corrosion resistant aluminum in the USA, it also trims mass up front and preserves structural strength for long service.
Engineered Core Notch for Seamless Power Steering Integration
The radiator core features a precision cut notch that aligns exactly with the Impala's power steering box, allowing the assembly to drop into the chassis without shaving or relocating any components. This tailored clearance maintains factory mounting points and preserves the original steering geometry, ensuring the B Body frame remains balanced and true to its intended design. By eliminating custom trimming, installers save time and reduce the risk of misalignment that could compromise handling. The result is a plug-and-play solution that integrates with the vehicle's structure while supporting spirited driving and precise control.
Temperature-Activated Dual Fans for Adaptive Airflow Management
Equipped with two electric fans governed by coolant temperature sensors, this assembly delivers airflow exactly when it's needed. In slow-moving traffic or idle conditions, the fans engage to prevent heat soak and keep the LS engine within its optimal operating range. Under heavy throttle or on hot days, both fans work in concert with the aluminum core to shed heat quickly, safeguarding horsepower and preventing overheating. Each fan mounts to factory-style brackets and connects via simple wiring, making the setup straightforward without requiring additional relays or custom switchgear.
High-Conductivity Aluminum Core for Rapid Heat Dissipation
Crafted from premium grade aluminum, the radiator core excels at moving heat from coolant into the surrounding air. Aluminum's superior thermal conductivity accelerates heat transfer-a must for the higher output of an LS swap-and its reduced mass lowers the front-end weight to improve overall handling. In addition, the natural corrosion resistance of aluminum helps prevent pitting and electrolysis, extending service life and reducing maintenance intervals. Together, these properties ensure reliable cooling performance for both daily cruising and track sessions.
Flexible Finish Options Balancing Style and Durability
Builders can choose the classic bare aluminum finish to showcase polished surfaces or opt for a robust black epoxy coating designed to resist moisture, abrasion, and environmental contaminants. The epoxy layer forms a protective barrier that holds up to road debris, frequent cleaning, and high under-hood temperatures without flaking or fading. All radiators undergo stringent quality control procedures in the United States to verify consistent fit, finish, and corrosion protection. This finish versatility lets enthusiasts match their engine bay aesthetics while ensuring long-term durability.
