LS Radiator with Fans for 1965-1970 Chevy Impala Auto Trans B-Body
Fitting an LS powertrain into a 1965-1970 Impala brings one common challenge, radiator clearance around the factory steering box that often demands cutting or component relocation under the hood. This radiator drops into factory B-Body rails without modification by using a notched upper support rail and original mounting bosses for precise alignment. Equipped with dual electric fans and a full height aluminum core it sustains stable coolant flow from city streets to high speed runs. Built from corrosion resistant aluminum and designed to preserve front end balance it removes fitment headaches and keeps the swap focused on performance tuning rather than fabrication.
Precision Notched Upper Mount for Power Steering Clearance
The notched upper support rail is engineered to clear the steering box without any trimming of frame rails or relocation of pumps. By matching original mounting bosses the radiator installs in the factory frame rails exactly like the stock unit. This arrangement preserves front suspension geometry and prevents alignment issues during assembly. The direct drop in fit means installers can focus on tuning performance instead of worrying about fabrication tasks.
Dual Electric Fans Ensuring Consistent Cooling Under Load
The pair of fans activates with ignition and draws air evenly across the entire core. Their motor housings are designed to limit noise while maintaining strong airflow in city traffic or highway speeds. Locating the fans within the shroud helps keep airflow balanced across the surface and sustains transmission temperature control. This integrated solution eliminates the need for additional brackets and helps maintain front end balance when paired with an LS powertrain.
Full Height Core for Superior Heat Extraction
This radiator core is built from premium aluminum for its thermal conductivity and corrosion resistant properties. The full height design provides ample surface area for coolant to pass through closely spaced channels that accelerate heat transfer. Removing heat more rapidly prevents hotspots and keeps engine and transmission temperatures within safe ranges at the track or on open roads. The low mass of the aluminum core also contributes to reduced overall weight under the hood improving handling of the classic chassis.
Finish Variants Combining Protection and Classic Appeal
Builders can choose the bare aluminum that highlights the metal s natural sheen or select a black epoxy coating that adds a protective layer against road salts and moisture. The coating is applied locally under strict quality checks to ensure even coverage and adhesion through repeated heating cycles and coolant exposure. Both finishes resist surface pitting and maintain their integrity over time. This choice of finish delivers corrosion defense while preserving the period correct look of the Impala engine bay.
