1965-1970 Chevy Impala LS Radiator with Fans for Automatic Transmission
When fitting an LS powertrain into a classic Impala, radiator clearance around the power steering box can force cutting or component relocation. The 1965-1970 Impala Radiator (Auto Trans) with Fans uses a notched upper support rail and original mounting bosses so it drops into factory frame rails without modification. Equipped with dual electric fans and a full height aluminum core, it sustains stable coolant flow in busy traffic and spirited driving. Its lightweight, corrosion resistant design preserves front end balance and keeps the swap process focused on tuning rather than fabrication.
Precision Notched Upper Support Rail
The notched upper support rail is engineered to clear the factory power steering box without trimming frame rails or relocating pumps. By aligning with original mounting bosses the radiator drops directly into the factory rails exactly as the stock unit did. This preserves the front suspension geometry and reduces alignment challenges during installation. The result is a clean under hood presentation and a straightforward bolt in process that lets builders concentrate on dialing in engine performance rather than wrestling with fitment modifications.
Integrated Dual Electric Fans for Balanced Cooling
The pair of electric fans activates with the ignition to sustain airflow across the entire core even during heavy stop and go traffic or spirited highway runs. Each fan's motor housing is optimized to limit noise while drawing heat evenly from the radiator surface. Their lightweight assemblies help maintain front end balance when paired with an LS powertrain. This integrated cooling solution keeps engine and transmission temperatures within ideal limits under varying load conditions without the need for auxiliary shrouds or brackets.
Full Height Aluminum Core for Efficient Heat Rejection
This radiator core is crafted from premium aluminum valued for exceptional thermal conductivity and inherent resistance to corrosion. Its full height design provides a maximized surface area for coolant flow and rapid heat extraction. Closely spaced cooling channels remove heat more effectively than conventional cores and help prevent localized hotspots. The low mass of the aluminum core also reduces the overall weight beneath the hood, contributing to improved handling on the classic B-Body chassis.
Coating Choices for Visual Appeal and Corrosion Protection
Builders can choose a raw aluminum finish to highlight the metal's natural luster or select a black epoxy coating that adds a chemical barrier against road salts and moisture. The epoxy is applied in a domestic facility under stringent quality inspections to ensure uniform coverage and long term adhesion. Both finishes resist coolant drips and repeated temperature cycles without flaking or pitting. These finish options merge period-correct style with durable protection so the radiator retains both performance and appearance over time.
