LS Radiator for 1982-1992 Chevy Camaro and Pontiac Firebird Automatic Transmission
If you are swapping an LS engine into a 1982-1992 Camaro or Firebird automatic transmission, the 1982-1992 F-Body LS Radiator (Automatic Trans) delivers reliable coolant control from initial startup through spirited driving. Out of the box it mounts to stock points for both 4L60E and 4L80E applications and uses a fully TIG welded aluminum core to channel heat away faster than factory radiators without any aftermarket brackets. Builders will appreciate that the bare alloy finish promotes natural heat loss while the optional epoxy coat adds a barrier against corrosion in humid or salty environments. Made in the USA to exacting tolerances, it ensures consistent alignment with F-Body frames and maintains stable operating temperatures whether you are cruising back roads or heading for the strip.
Precision Alignment for F-Body Frame and Automatic Transmission
The 1982-1992 F-Body LS Radiator is engineered to bolt directly to the factory mounting points on both 4L60E and 4L80E automatic transmissions, eliminating the need for custom adapters or cutting. By maintaining exacting tolerances during assembly, each unit aligns perfectly with the Camaro and Firebird chassis, ensuring a snug fit that minimizes vibration and stress on surrounding components. This precision fit not only streamlines installation for experienced builders and first-time swappers alike but also preserves the integrity of the original frame openings. Because the radiator secures cleanly to stock points, there is less chance of misalignment over time, which can lead to leaks or premature wear on hoses and fittings. With a product made in the USA under tight quality controls, installers gain confidence that every radiator will meet the same exact standard for fit and finish.
Fully TIG Welded Aluminum Assembly for Structural Integrity
This radiator features a fully TIG welded construction that joins the tanks and core with consistent, high quality weld beads free of voids or splatter. TIG welding offers superior penetration and clean joints, creating a robust seal that resists cracking under thermal cycles and vibration seen in spirited driving or track use. The reliability of these welds translates directly into long term leak protection, reducing maintenance concerns and downtime. Additionally, the precise nature of the TIG process helps maintain internal coolant pathways without distortion, supporting unrestricted flow from the engine to the core. By combining craftsmanship with modern welding techniques, the assembly withstands the demands of an LS engine swap while preserving core strength and alignment.
Premium Aluminum Core for Rapid Heat Dissipation
Aluminum is chosen for its excellent thermal conductivity, allowing the core to absorb and release heat faster than traditional materials. The optimized design maximizes internal surface area and coolant velocity, helping to stabilize operating temperatures during sustained high load or stop-and-go traffic. As coolant circulates through the precision-formed tubes and fins, heat is shed quickly into passing air, reducing the risk of hot spots and boil over that can plague underdeveloped systems. This characteristic is especially valuable in performance applications where cylinder head and oil temperatures must remain in a narrow window for consistent power output. By harnessing the innate properties of aluminum, the radiator ensures efficient cooling without bulky size or excessive weight.
Coating Choices to Guard Against Corrosion
Customers can select a classic bare aluminum finish for maximum radiant heat loss or opt for a uniform black epoxy coating to protect against moisture, salt spray, and road debris. The bare surface allows unimpeded heat radiation, while the epoxy layer adds a durable barrier that retards oxidation and pitting in humid or coastal environments. Each finish is applied under controlled temperature and curing conditions, ensuring consistent thickness and adhesion for reliable long term performance. Keeping internal passages free of rust is critical for maintaining coolant flow and avoiding blockages, particularly when using aftermarket coolants or additives. By offering two treatment options, this radiator adapts to a range of climates and driving styles without compromise.
