1965-1970 Chevy Impala LS Swap Radiator with Fans
When installing an LS engine into a 1965-1970 Chevy Impala B Body, space around the factory power steering box often demands custom trimming and relocation of components. This 1965-1970 Impala Radiator (Manual Trans) with Fans addresses that challenge with a precision notched aluminum core that hugs factory mount points and guides coolant through its rows without interference. Dual electric fans governed by coolant sensors kick on at low speed and in heavy load scenarios to maintain stable temperatures. Built in the USA, it matches original fixings and trims front end mass for balanced steering geometry and handling.
Precision Engineered Notch for Power Steering Clearance
The radiator core features a precision cut that aligns with the 1965-1970 Impala's power steering box, allowing the assembly to drop into place without modifying the chassis. This exact fit preserves factory mounting points and retains original steering geometry, ensuring balanced handling. By eliminating the need for trimming or part relocation, installers save time and avoid potential errors that can arise when custom modifying sheet metal. The notched design was developed specifically for the B Body frame, delivering a direct solution for LS engine swaps. This approach ensures the cooling assembly works in harmony with the vehicle’s structural layout.
Adaptive Dual Fan System for Reliable Cooling
This assembly includes two electric fans governed by coolant temperature sensors to deliver airflow precisely when it is needed. In stop-and-go traffic or during idle periods, a single low-speed fan can engage to prevent heat soak, while heavy load conditions trigger both fans for maximum air movement. These fans mount to factory-style brackets and connect via straightforward wiring, avoiding the need for extra relays or aftermarket controls. The system maintains optimum engine temperature under varied driving scenarios, from daily commuting to spirited backroad runs. Cooling performance remains consistent without user intervention or guesswork.
High Conductivity Aluminum Core Design
Constructed from premium grade aluminum, the radiator core excels at transferring heat from the coolant to the surrounding air. Aluminum’s natural thermal properties accelerate heat dissipation, which is critical for the higher output of an LS powerplant. The reduced mass of the material also trims weight from the front of the vehicle, helping retain responsive steering and cornering balance. Moreover, aluminum offers inherent corrosion resistance, minimizing the risk of pitting and electrolysis over time. Together, these properties combine to provide efficient cooling and maintain long engine life.
Finish Options Delivering Style and Protection
Customers can choose a classic bare aluminum look to highlight polished surfaces or opt for a durable black epoxy coating that resists moisture and abrasion. The epoxy finish forms a protective layer that stands up to road debris and high under-hood temperatures without peeling. Both finish options undergo rigorous quality checks in the United States to guarantee fit, finish and corrosion resistance. This versatility lets builders match the engine bay aesthetics while ensuring lasting protection against environmental factors. Regardless of choice, the result is a radiator that looks as good as it performs.
