LS Swap Radiator for 1963-1972 Chevy Corvette Y-Body Manual Transmission
Whether you're installing an LS engine behind the manual transmission of a 1963-1972 Corvette, this Pin Mount Radiator restores coolant flow where the original design falls short. Crafted from TIG welded aluminum tanks and core, it slides into the Y Body chassis at factory mounting points without cutting or adapters. Its optimized core layout and aluminum construction enable rapid heat rejection under both street and track conditions. Drivers benefit from reliable temperature control and lasting corrosion resistance for many seasons on the road.
Precision TIG Welding Ensures Structural Integrity
All seams between the tanks and core are fused using TIG welding techniques that produce consistent and smooth beads. This method creates a seal that resists leaks under constant pressure and vibration when fitted to a classic Corvette chassis. By controlling heat input precisely, the welding preserves the properties of the aluminum, reducing the risk of warping even during repeated temperature cycles. The result is a cooling component that maintains its form and function over many seasons on both the street and the track.
Premium Aluminum Core Optimized for Rapid Heat Rejection
The core is fabricated from high conductivity aluminum that excels at drawing heat away from the coolant and transferring it to the air. Its fin density and tube layout maximize surface area without hindering flow, so the engine maintains safe temperatures under heavy loads. Aluminum resists corrosion naturally, protecting against electrolysis and the effects of road chemicals. Drivers will notice faster cooldown after spirited runs, ensuring consistent performance on long drives or track sessions.
Effortless Installation Using Original Pin Mounts
This radiator slides into the factory pin locations on the Y body chassis, eliminating the need for cutting or bracket fabrication. It aligns precisely with the manual transmission clearance and hood latch geometry, making installation straightforward even for those with limited shop experience. OE style hardware secures the unit in place, reducing install time and minimizing errors. That turn key fitment means you get back on the road faster with confidence in the assembly.
Coating Choices for Durability and Aesthetics
Choose a natural bare finish that highlights the aluminum grain and requires minimal upkeep, or select a black epoxy layer for added protection against moisture and grime. Both options go on in a controlled environment to ensure even coverage without altering heat transfer characteristics. The epoxy layer adds a barrier that helps prevent oxidation in harsh conditions, while the bare option delivers a classic look that blends seamlessly under the hood. Each finish supports lasting corrosion resistance and a clean appearance year round.
