LS Radiator for 1963-1972 Chevy Corvette Y-Body Auto Transmission
When preparing to swap an LS motor into a 1963-1972 Y Body Corvette with automatic transmission, maintaining proper coolant flow and temperature control can become a serious challenge. This 1963 to 1972 Corvette Pin Mount Radiator (Auto Trans) installs directly into existing frame pins, aligning with the factory fan shroud and preserving hood clearance without any custom brackets. Constructed from TIG welded aluminum tanks and a high efficiency core, it delivers consistent coolant circulation and rapid heat rejection to protect both engine and automatic transmission under demanding driving conditions. It supports spirited runs and highway cruises in your classic Corvette by combining perfect fitment for the original chassis with reliable temperature regulation.
Precision TIG Welding for Structural Integrity and Consistent Cooling
This radiator employs full TIG welding on both tanks and the core to create smooth, seamless joints that enhance coolant flow and heat transfer. Unlike less precise methods, TIG fusion produces minimal weld spatter and reduces turbulence inside the passages, helping maintain steady circulation at all engine speeds. The robust welds withstand vibration and repeated pressure cycles, lowering the chance of fatigue cracks or leaks over time. Production in the United States ensures each unit meets rigorous quality control and delivers dependable performance for spirited drives and extended highway runs.
Direct Fit into 1963 to 1972 Y Body Frame Pins
Designed to install using the factory pin mounts, this radiator drops into the 1963 to 1972 Corvette Y Body chassis without cutting or custom brackets. It aligns perfectly with the stock fan shroud and retains proper hood clearance, preserving the car's original airflow pathways and under hood appearance. Builders only need the standard hardware to secure it in place, reducing installation complexity and shop time. By maintaining factory mounting geometry, airflow remains efficient from idle through high-speed operation.
Coating Options for Corrosion Resistance and Classic Appearance
Choose the raw aluminum finish to maximize thermal conductivity through direct metal exposure, or opt for the black epoxy layer to guard against moisture and road debris. The epoxy is applied in a controlled process so it adheres uniformly without adding excess thickness that could impede heat transfer. Both finishes retain the clean, period-correct look beneath the hood while protecting the aluminum from oxidation in varied climates. This flexibility allows owners to balance corrosion protection and under hood style based on local conditions and maintenance habits.
All-Aluminum Construction for Rapid Heat Rejection and Weight Savings
Constructed entirely from premium aluminum, this radiator excels at shedding heat to protect an LS engine and automatic transmission under heavy load. Aluminum tubes and fins offer high thermal conductivity for quick exchange between coolant and ambient air, while the reduced coolant volume design helps the powertrain reach optimal temperature faster. The lightweight assembly also minimizes added front-end mass, preserving the Corvette's original handling characteristics. Together, these design choices ensure reliable temperature control during spirited runs and long-distance cruising.
