LS Pin-Mount Radiator for 1963-1972 Chevy Corvette Manual Transmission
When fitting an LS powerplant behind the manual transmission of your 1963-1972 Corvette, this pin mount radiator delivers targeted cooling where stock units fall short. Constructed from TIG welded aluminum tanks and core, it installs directly into the original chassis without cutting or fabrication. It supports LS engine swaps with manual gearboxes and offers superior thermal efficiency and corrosion resistance for both street driving and track days.
Precision TIG Welding for Lasting Durability
Every tank and core joint on this Corvette radiator is completed with TIG welding to deliver smooth, consistent beads that stand up to stress and vibration. This welding method ensures a virtually leak-free seal, critical when adapting modern LS engines into a classic chassis. The precise heat control of TIG welding also preserves the strength of the aluminum, reducing the risk of warping under extreme temperature cycles. As a result, owners benefit from a cooling solution that resists fatigue and maintains integrity year after year.
Optimized Thermal Efficiency with Premium Aluminum Core
The core is crafted from high-conductivity aluminum that excels at drawing heat away from the coolant and shedding it into passing air. Its fin density and tube layout are calibrated to maximize surface area without restricting flow, so the engine runs cooler under heavy loads. Aluminum's natural corrosion resistance further protects against electrolysis and road salt exposure, extending service life. Drivers will notice quicker recovery after hard pulls, whether on the street or at the track.
Seamless Direct-Fit into 1963 to 1972 Corvette Manual Models
This radiator retains the factory pin-mount locations, requiring no cutting, trimming, or custom brackets. It aligns perfectly with stock transmission clearance and hood latch geometry, allowing even novice mechanics to bolt it in using OE-style hardware. The plug-and-play nature of the design cuts install time dramatically and eliminates guesswork. That simplicity translates to more time behind the wheel and less time in the garage.
Finish Options to Match Style and Protection
Choose between a natural bare finish that emphasizes the aluminum's grain or a sleek black epoxy coat that adds an extra barrier against road grime and moisture. Both finishes are applied in controlled conditions to ensure uniform coverage and adhesion, with no effect on cooling performance. The bare option offers a classic look and minimal maintenance, while the epoxy choice enhances corrosion resistance and complements darker engine bays. Either way, your Corvette retains a clean aesthetic without sacrificing function.
Built to maintain optimal engine temperatures under hard use this radiator is the reliable choice for LS conversions. For the same radiator but with fan see our 1963-1972 Corvette Pin-Mount Radiator (Manual Transmission) with Fan.
