1965-1970 Chevy Impala Radiator with Fans for LS Engine Swap
The 1965-1970 Impala Radiator (Manual Trans) with Fans was engineered to address clearance and cooling needs when installing an LS engine into a Chevy Impala B Body with a manual transmission. Aluminum core notches precisely around the factory power steering box to preserve original mounting points and maintain steering geometry as coolant flows uninterrupted. In traffic or under heavy load, sensor governed dual electric fans adjust speed to keep engine temperatures in check. Assembly in the USA ensures consistent fitment, trims mass at the front for balanced handling, and drops into place without modifications.
Precision Notched Core for Power Steering Clearance
Our radiator core is expertly notched to match the contour around the factory power steering box on 1965 to 1970 Chevy Impala B Body models. This exact alignment preserves original mounting points and the factory steering geometry. Installers can drop the assembly into the frame rails without trimming sheet metal or relocating hoses. The result is a streamlined swap process that safeguards chassis integrity and ensures precise coolant flow path around the steering gear.
Sensor Governed Dual Electric Fans for Adaptive Cooling
Two electric fans respond to coolant temperature signals to provide airflow exactly when engine heat rises. In slow traffic or idle, one fan runs at a reduced speed to prevent heat soak. When load increases or speed drops, both fans operate to maximize air movement across the aluminum core. Factory style mounting brackets and straightforward wiring simplify connection without extra relays or modules. This adaptive design keeps LS engines running within ideal temperature range under varied driving conditions.
Premium Aluminum Construction for Thermal Efficiency
Constructed from high quality aluminum, the radiator core excels at transferring heat from the coolant to the surrounding air. Aluminum’s natural thermal conductivity allows rapid heat rejection critical for LS engine output. Its lightweight nature reduces front end mass, helping maintain balanced handling on the Impala chassis. Additionally aluminum resists corrosion and pitting over time, protecting against electrolysis in mixed metal cooling systems and extending service intervals.
Durable Bare or Epoxy Coating Options
Customers can choose a polish ready bare aluminum finish to showcase engine bay detail or select a black epoxy coating for long term protection. The epoxy layer resists moisture, road debris, and under hood heat without peeling or cracking. Both options are produced and inspected in the United States to guarantee consistent quality and fit. This ensures that the radiator not only looks factory precise but also stands up to rigorous daily use and performance driving.
