LS Radiator for 1965-1970 Chevy Impala Manual Transmission
Installing an LS engine behind a manual transmission in a 1965 to 1970 Impala often creates space constraints up front, especially around the power steering box. This radiator for manual transmission swaps fits the original core support and offers precision clearance for the steering box with no frame rail trimming or hose rerouting. Featuring a full width aluminum core for rapid heat release and inherent corrosion resistance, it preserves stock layout for a tidy engine bay and reliable coolant circulation. Each unit is made to precise domestic standards, arrives ready for drop in installation, and preserves chassis geometry for reliable service and strong resale appeal.
Engineered Notch for Power Steering Box Clearance
The radiator includes a precision machined notch that aligns exactly with the power steering box location on 1965-1970 Impala B-body frames. By preserving original core support and avoiding any frame rail trimming, installers achieve a true drop in fit without modifying the chassis. This clearance maintains the factory layout, allowing hoses and lines to route correctly and eliminating potential interference with the steering gear. Fitment brackets engage reliably, so minimal adjustment is needed to secure the unit and uphold the Impala's stock geometry. The outcome is a clean engine bay and an installation process that saves time while protecting surrounding components.
Full Width Aluminum Core Maximizing Heat Rejection
At the heart of this cooling solution lies a full width core crafted from high quality aluminum, chosen for its exceptional thermal conductivity. The expanded surface area accelerates heat transfer from coolant to air under sustained or spirited driving conditions. Internally, uninterrupted flow channels promote uniform distribution, preventing local hotspots that can stress joints or cause premature boil-over. The lightweight nature of aluminum also contributes to a modest reduction in front-end mass, which can improve steering feel and overall balance on the road. Corrosion resistance inherent to this material further helps maintain peak performance across seasons.
Corrosion Protection with Bare Aluminum or Black Epoxy Finish
Enthusiasts may choose between a classic bare aluminum surface or a black epoxy finish, both applied under strict quality controls to ensure consistent coverage. The epoxy option creates a robust barrier against moisture, road additives and airborne contaminants, extending service intervals without compromising heat rejection. Conversely, the bare metal treatment highlights the natural sheen of aluminum, seamlessly integrating with restorations that value period-correct engine bay aesthetics. Neither option alters the core's precise dimensions or disrupts its thermal characteristics, so cooling efficiency remains at the designed level. This flexibility lets builders tailor appearance while safeguarding long-term durability.
Domestic Fabrication Ensuring Consistent Fit and Quality
Manufactured in the United States, each radiator is produced under rigorous inspection standards that guarantee dimensional accuracy and material traceability. Multiple checks during welding, machining and final assembly eliminate the fitment variances often found in imported replacements. Local sourcing of high quality aluminum and a controlled production process yield consistent bracket alignment and reliable mounting to the factory core support. This close oversight preserves chassis geometry and supports daily reliability, whether on spirited drives or in stop-and-go traffic. In addition, domestic production offers faster access to technical support and replacement parts, helping maintain resale value and ownership satisfaction over time.
