LS Radiator with Cooling Fans for 1965-1970 Chevy Impala Auto Trans
Installing an LS engine into a 1965 to 1970 Chevy Impala with an automatic transmission usually runs into radiator clearance hurdles around the power steering box. This Impala Radiator (Auto Trans) with Fans solves that by using a notched upper support rail and original mounting bosses for a true drop in fit. Equipped with dual electric fans mounted within the shroud and a full height aluminum core, it sustains stable coolant flow whether crawling through traffic or winding down the highway. Built from corrosion resistant aluminum for lightweight durability, this radiator keeps focus on tuning performance instead of fabrication tasks.
Precision Mounting Rail for Seamless Power Steering Clearance
The notched upper support rail is engineered to clear the original power steering box without any cutting or relocation of components. By aligning with the factory mounting bosses, the radiator installs directly into the 1965 to 1970 Impala frame rails just like the stock unit. This approach preserves front suspension geometry and prevents misalignment issues during assembly. Installers can focus on tuning the LS swap rather than fabricating custom brackets or modifying the frame.
Dual Electric Fans Deliver Consistent Engine and Transmission Cooling
Equipped with two high-capacity electric fans mounted within a purpose-built shroud, this radiator maintains steady airflow when idling in traffic or cruising at speed. The integrated design balances air delivery across the full core surface, preventing hotspots and ensuring both engine and automatic transmission remain within safe temperature ranges. Fans activate with engine temperature and eliminate the need for aftermarket brackets or external wiring loops. This built-in solution also helps retain correct front end weight distribution in your classic Impala.
Full Height Aluminum Core for Rapid Heat Rejection
The full height core is fabricated from high quality aluminum prized for its thermal conductivity and resistance to corrosion. Coolant passes through closely spaced tubes and thin fins, accelerating heat transfer away from the LS engine under intense load. This rapid heat rejection reduces the risk of overheating on the street, the autocross circuit, or long highway hauls. The lightweight nature of the aluminum core also eases overall nose weight, benefiting handling and steering response in the vintage chassis.
Custom Finish Choices for Durability and Classic Engine Bay Style
Builders may opt for the natural bare aluminum finish to highlight the core's metallic sheen, or choose a black epoxy coating to add a protective layer against road salts and moisture. The coating process follows strict quality checks to ensure uniform coverage and adhesion through repeated heat cycles and coolant exposure. Both finishes resist surface pitting and maintain their integrity over years of operation. This level of corrosion defense allows you to preserve a period-correct underhood appearance while safeguarding long term performance.
