LS Swap Radiator with Fans for 1965-1970 Chevy Impala Automatic Transmission
When adapting an LS automatic transmission into a 1965 to 1970 Chevy Impala B Body, finding a radiator that aligns with factory mounting points and clears the power steering box can be a major hurdle. This 1965 to 1970 Impala Radiator (Auto Trans) with Fans solves that by incorporating a notched upper rail and original style mounts so the unit installs without cutting frame rails or relocating components. Equipped with dual electric fans and a durable aluminum core, it sustains consistent cooling flow in heavy traffic or spirited street use while its lightweight construction maintains proper front end balance.
Seamless Integration with Impala Power Steering Packaging
This radiator is engineered with a precision notched upper rail that clears the factory power steering box without any modifications. By maintaining original mounting bosses and using stock hardware, the unit drops into the 1965 to 1970 Impala frame rails without cutting or relocating components. Builders benefit from a true bolt-in solution that preserves factory geometry, reducing installation time and eliminating alignment headaches. Retaining the factory style mounting points also ensures a clean, period-correct appearance under the hood. The result is a seamless fit that lets you focus on tuning the LS automatic transmission swap rather than fabricating custom brackets.
Engineered Dual Fan Setup for Optimal Airflow
Two high-capacity electric fans are preinstalled and wired to engage whenever the ignition is on, guaranteeing continuous airflow even in heavy stop-and-go traffic. Their strategic placement along the core draws heat away from coolant rapidly, preventing hotspots that can degrade seals and gaskets under hard driving. Because the fans are tuned for both cooling efficiency and quiet operation, you gain reliable performance without excessive noise on street runs or road-course laps. Lightweight fan housings also help maintain balanced front axle weight when pairing this radiator with an LS powertrain. This integrated cooling package delivers consistent temperature control for automatic transmission applications under a wide range of driving conditions.
Premium Aluminum Core and Protective Coating Choices
At the heart of this assembly lies a full-height aluminum core crafted from high quality alloy prized for its superior thermal conductivity and natural corrosion resistance. Aluminum’s ability to transfer heat quickly keeps coolant temperatures in check, giving your LS engine and transmission a dependable thermal envelope. Builders can select a classic bare finish to maximize heat reflection and showcase the metal’s raw sheen, or opt for a black epoxy coating that repels road salts, coolant drips, and moisture. The epoxy barrier extends service life by guarding against pitting and chemical attack, while still allowing for rapid heat rejection. Both finishes are applied in the USA to ensure consistent coverage and durability under repeated heat cycles.
