1965-1970 Chevy Impala LS Radiator for Automatic Transmission with Fans
When installing an LS engine into a 1965 to 1970 Chevrolet Impala with an automatic transmission, radiator clearance near the power steering box can derail a project. The 1965-1970 Impala Radiator (Auto Trans) with Fans addresses this with a notched upper rail that mounts to factory bosses for drop in fit with no cutting or relocation. Constructed from corrosion resistant aluminum, its full height core and dual electric fans deliver stable coolant flow in city and track use. Lightweight design reduces nose weight while supporting thermal management at idle and speed. Made in USA for direct fit installation, this radiator lets you focus on tuning instead of fabrication.
Precision Fitment for 1965-1970 Impala with Auto Trans and LS Power
This radiator is engineered specifically for 1965 through 1970 Chevrolet Impala installations paired with an automatic transmission and an LS engine. Each core is notched precisely around the power steering box location, eliminating modification or trimming during installation. Compatibility with MuscleRods frame mounts ensures correct engine placement and proper drivetrain angles, preserving factory driveline geometry and reducing stress on universal joints. The precise tank-to-frame clearance maintains the original firewall setback and preserves underhood aesthetics.
Efficient Cooling System Integration
The dual fans installed on this radiator are arranged to deliver consistent airflow across the entire core surface. Mounted on the rear face of the core, they create a concentrated cooling curtain that prevents hot spots under sustained highway or track use. Dual fan operation is driven by a high amp relay kit that responds to thermostat signals for on demand performance, keeping coolant temperatures within optimal range. This approach ensures continuous heat dissipation even in slow traffic or heavy load scenarios, improving reliability of the LS engine and automatic transmission under all driving conditions.
Premium Aluminum Construction and Endurance
Constructed from premium aluminum, the core features brazed tube and fin architecture for maximum heat transfer efficiency. Aluminum end tanks resist corrosion and handle thermal expansion without cracking, while internal baffles guide coolant flow to eliminate air pockets. Every unit is manufactured in the United States under stringent quality controls, assuring weld integrity and precision brazing processes. This domestic production guarantees consistent material standards and delivers long operational life for classic Impala powertrains that demand both performance and durability.
Engineered for 1965 to 1970 Impalas with an automatic transmission and an LS engine, this radiator offers corrosion resistant aluminum construction and stable coolant temperatures in stop and go traffic or track use for reliable cooling under all conditions.
