LS and LT Engine Swap Radiator for 1959-1964 Chevy Impala B-Body
When you fit a modern LS or LT engine behind the automatic transmission in a 1959-1964 Impala, the stock cooling system often falls short. This 1959-1964 Impala Radiator (Auto Trans) features a full aluminum tube and fin core paired with precision TIG welded tanks that resist corrosion and vibration while dissipating heat rapidly. Installation is simplified by aligning inlet and outlet ports with factory locations, and matching original mounting points ensures a true drop in fit for the Impala B Body. Consistent coolant flow under varied driving conditions protects both engine and transmission components and maintains chassis integrity.
TIG Welded Aluminum Tanks for Leak Free Performance
The radiator uses TIG welding to fuse tanks and core elements into one sturdy unit. This process employs a precise weld pool and inert gas shield to form seams with deep penetration and minimal porosity. As a result the joint walls resist crack initiation under constant vibration and thermal cycling. Clean bead profiles also help maintain unblocked passages for coolant flow. This method plus a full aluminum structure enhances reliability under daily drive loads and towing duty.
Efficient Aluminum Tube and Fin Core Heat Transfer
At the center of the design a full aluminum tube and fin core balances rapid heat extraction with lightweight construction. Thin walled tubes carry hot coolant into dense fin arrays where moving air strips heat quickly. The core geometry is tuned to preserve coolant velocity without overloading the pump impeller. This ensures stable engine temperatures even at high output or highway speed. The lightweight design also contributes to a balanced front weight distribution and more responsive steering feel.
Black Epoxy and Bare Aluminum Finishes for Durability and Style
Owners can choose a classic bare aluminum look or a protective black epoxy coating applied in an oven for uniform coverage. Bare aluminum highlights weld artistry and accepts arrive patina or polish for a custom look. The epoxy finish forms a barrier against road salt and moisture to inhibit corrosion without affecting thermal performance. Both options are engineered to preserve cooling efficiency and resist chipping under debris impact. This choice lets builders match engine bay aesthetics to overall restoration themes.
Factory Alignment and Bolt In Fit for Effortless Installation
Designed specifically for Impala B Body models from 1959 through 1964 the radiator aligns precisely with original support points and fluid lines. No adapters brackets or custom tubing are required to secure the unit within the stock core support structure. This direct bolt in approach cuts installation time and reduces the chance of leaks from misaligned hoses. Matching inlet and outlet placements also preserves frame integrity and resale value. Installers can focus on plug in wiring and plumbing details instead of metal fitting.
