Radiator for LS and LT Engine Swaps in 1970-1981 Camaro and 1978-1988 G-Body
The 1970-1981 Camaro and 1978-1988 G body Radiator (AutoTrans) is engineered to keep coolant temperatures under control when fitting an LS or LT V8 to a classic Camaro or G body chassis with a 4L60E or 4L80E automatic transmission. Its 100 percent TIG welded aluminum core and tanks resist corrosion while delivering fast heat rejection in demanding driving conditions. Leveraging existing frame rails and upper radiator mounts, installation avoids cutting or relocating factory supports. Examples of compatible platforms include Chevy Camaro, Monte Carlo, Buick Regal and Grand National, Oldsmobile Cutlass, Pontiac Grand Prix, Chevy Nova, Caprice, Impala, Malibu, El Camino and other G body models, ensuring a precise fit without custom brackets.
Precision TIG Welding for Core Durability
The radiator core and tanks are joined with 100 percent TIG welding using high-grade aluminum to form uniform, leak-free joints. This method creates strong bonds that withstand thermal cycling and vibration, ensuring coolant pressure remains consistent during spirited driving. Uniform weld beads also enhance heat conduction across the tank-to-core interface, speeding heat transfer away from the engine. Built domestically under strict standards, these welds deliver reliable service in both street and track settings.
Optimized Cooling Path for LS and LT Engines
A meticulously designed tube and fin layout increases the surface area in contact with coolant, promoting rapid heat rejection even under heavy load. The flow path guides fluid through a precise sequence of channels that maintain stable operating temperatures for both LS and LT V8 powerplants. By matching the demands of automatic transmissions such as 4L60E and 4L80E, this system reduces the risk of overheating and supports sustained performance. Consistent coolant management also protects engine components from thermal stress.
Durable Finish Options to Prevent Corrosion
Choose between a classic bare aluminum surface that naturally resists moisture or a black epoxy finish that puts an extra barrier against salt, road grime, and oxidation. The epoxy coating conforms to metal for even coverage and seals microscopic pores, blocking corrosion before it starts. In bare form, the aluminum can be polished to maintain a factory fresh appearance, while the coated version requires only minimal cleaning. Both finishes are applied in controlled environments to guarantee uniform protection.
Straightforward Installation Using Stock Mounts
The radiator is engineered to fit directly into existing frame rails and upper radiator mounts on classic Camaros from 1970 to 1981 and G body platforms built between 1978 and 1988, eliminating the need for custom brackets or cutting. It aligns perfectly with factory support structures and lines up with automatic transmission connections for 4L60E and 4L80E setups. This direct-fit approach reduces installation time and minimizes the chance of fitment issues. Enthusiasts can rely on this radiator to simplify their engine swap project without compromising on performance or reliability.
