LS/LT Radiator for 1970-1981 GM A-Body and 1978-1988 G-Body Cars
Swapping an LS or LT engine into a 1970 to 1981 Camaro or a 1978 to 1988 G Body chassis often runs hot, and this radiator is engineered to maintain stable coolant temperatures when using a 4L60E or 4L80E automatic transmission configuration. It features a core and tanks fully welded with TIG technology in pure aluminum for rapid heat rejection under spirited driving, with a long service life free from corrosion and domestically built for consistent quality. Installation takes advantage of existing frame rails and upper mounts so there is no need for cutting or custom brackets, and compatibility covers Camaro Monte Carlo Regal Grand National Cutlass Grand Prix Nova Caprice Impala Malibu El Camino and other G-Body variants.
Precision TIG Welding for Enduring Strength
By joining the core and tanks with 100 percent TIG welding, this radiator delivers uniform bonds that stand up to constant vibration and temperature cycling. This method ensures coolant pressure remains stable under spirited driving and prevents leaks over time. High quality aluminum allows these welds to conduct heat efficiently across joints, speeding coolant flow and reducing hotspots near the engine. Domestic fabrication under strict protocols guarantees consistent weld integrity and long service life.
Advanced Thermal Management for LS and LT Applications
A carefully engineered tube and fin arrangement maximizes the surface area over which coolant circulates, promoting rapid heat rejection even under heavy acceleration. The internal flow path guides fluid through sequential channels tuned to LS and LT V8 cooling demands, preventing thermal buildup during high load operation. Automatic transmissions such as 4L60E and 4L80E benefit from this temperature control, which preserves fluid viscosity and enhances torque converter efficiency. Consistent coolant management also extends the life of engine components by minimizing expansion and contraction stress.
Finish Options Guarding Against Corrosion
Owners can choose a bare aluminum finish that naturally resists moisture or opt for a black epoxy coating that provides an extra barrier against road salt and grime. The epoxy layer conforms to all surfaces, sealing microscopic pores and halting oxidation before it starts. In uncoated form, the metal may be polished to a factory style shine with minimal effort. Both finishes are applied in a controlled environment to ensure uniform thickness and reliable corrosion protection from day one.
Seamless Fit with Stock Frame Mounts
Installation uses the factory frame rails and upper radiator mounts of classic Camaros and G body chassis, requiring no cutting or custom supports. It aligns precisely with the transmission cooling lines of 4L60E and 4L80E setups, reducing plumbing adjustments and the chance of leaks. This direct fit design shortens installation time and lowers the risk of alignment issues that can hamper performance. Technicians and hobbyists alike benefit from a streamlined swap process that keeps the classic appearance intact.
