LS Radiator with Fan for 1963-1972 Corvette Auto Transmission
Swapping an LS motor into a 1963-1972 Corvette Y Body with a 4L60E or 4L80E transmission often clashes with frame rails; the 1963-1972 Corvette Pin-Mount Radiator (Auto Trans) with Fan slips onto stock mounts while preserving original hoses. Its slim aluminum core promotes rapid heat rejection without adding front end mass, and full weld joints safeguard against leaks under repeated temperature cycles. Equipped with a single sixteen inch electric fan, it delivers steady airflow at idle with minimal amperage draw, protecting delicate wiring harnesses in your restored Corvette. Alignment to factory bolt locations ensures precise positioning and vibration resistance, making installation straightforward and reliable for any LS conversion project. Built in the USA, each radiator undergoes quality control to deliver consistent performance and long term durability under demanding driving conditions.
Precision Pin Mount Alignment for Corvette Y Body
This radiator assembly is engineered to slip directly onto the stock mounts of a classic Corvette Y body, preserving original steering and air conditioning line positions. By matching the factory bolt pattern for 4L60E and 4L80E transmissions, the unit maintains correct chassis geometry and coolant hose angles. Full weld joints at every tank and core intersection ensure that the assembly resists vibration and minimizes the risk of leaks during spirited runs or long highway stretches. The precise pin mount layout simplifies installation, eliminates the need for frame rail trimming, and results in a secure fit that holds coolant lines in their intended paths.
Optimized Aluminum Core for Rapid Heat Dissipation
Constructed entirely from high quality aluminum, the slim core maximizes thermal conductivity for quick transfer of engine heat to ambient air. An expanded tube layout combined with a dense fin pack increases surface area, promoting efficient heat rejection even under sustained high load conditions typical of an LS swap. Aluminum's innate resistance to corrosion keeps coolant passages clear over time, reducing maintenance intervals and preserving flow rates. Full penetration welding at all critical seams delivers long term durability and leak resistance under repeated temperature cycles.
Single 16 Inch Fan for Efficient Idle Cooling
Equipped with one 16 inch electric fan, this setup offers consistent airflow at idle without overtaxing the vehicle's electrical system. The fan pulls sufficient volume of air through the core face to prevent hotspots when traffic slows or the engine idles for extended periods. Direct mounting to the radiator frame removes the need for extra brackets or shrouds, ensuring uniform pressure distribution and improving overall fan performance. Low amperage draw protects the original wiring harness from excessive current, while quiet operation enhances enjoyment during restoration showcase events.
Coating Options for Corrosion Resistance and Visual Detail
Two distinct finish choices allow builders to tailor the aesthetic and protective properties to their project. The classic bare aluminum option highlights the workmanship of each weld seam and lends a bright, period-inspired appearance under hood. Alternatively, the black epoxy coating provides an extra barrier against moisture, abrasion, and chemical exposure without adding noticeable weight. Both finishes bond tightly to the core and tanks, resisting chipping and peeling even when exposed to fluctuating engine bay temperatures. This flexibility in appearance and protection ensures the radiator looks as good as it works for years to come.
