LS and LT Radiator with Dual Fans for 1970-1981 Chevy Camaros and 1978-1988 G-Body Vehicles
Whether you are swapping an LS or LT powerplant into a 1970 to 1981 Camaro or a 1978 to 1988 G Body with an automatic transmission this radiator assembly ensures consistent cooling under heavy traffic and spirited highway runs. Its TIG welded aluminum core teams with two electric fans to pull air evenly across the entire face at idle or when cruising at speed and prevents hot spots. Installation follows factory bracket points for 4L60E and 4L80E transmissions so mounts and frame rails remain unmodified for a straightforward drop in fit.
High-Grade Aluminum Core and Protective Coating
This radiator relies on a thick aluminum core prized for its outstanding heat transfer rate and light mass. Rapid extraction of thermal energy from the coolant helps keep LS and LT engines within optimal temperature windows under both cruising and traffic conditions. Builders can opt for an untreated aluminum finish to maximize raw conductivity or choose the black epoxy barrier to fend off corrosion and road debris. The epoxy layer bonds tightly without diminishing the core's ability to shed heat, preserving cooling efficiency. Made in the USA, this design balances toughness with thermal performance. Over a season of use, the coating maintains its adhesion and integrity, ensuring a long service life.
Precision TIG Welding for Leak Resistance
Every joint between the tanks and the core is executed using precision TIG welding, a process that produces a refined bead with minimal filler. By creating a uniform transition between aluminum pieces, these welds greatly reduce stress concentrations that can lead to cracks or leaks under thermal cycling. The smooth, continuous seams endure repeated expansion and contraction as coolant temperatures rise and fall, preserving the assembly’s structural integrity. This weld technique also resists warping, which can occur with less controlled methods. As a result, the radiator remains leak tight over many heat cycles without the need for reinforcement or rework.
Dual Electric Fans for Uniform Cooling
The assembly includes two high capacity electric fans mounted on a contoured shroud that directs airflow evenly across the full core surface. Because the fans operate independently from engine speed, they activate exactly when coolant temperature thresholds are reached, preventing hotspots during idling or in dense traffic. Carefully engineered blade profiles deliver a strong, steady flow of air while keeping acoustic levels in check. This arrangement mitigates heat soak and ensures stable engine temperature when tackling long climbs or extended periods of slow driving. The dual fan setup offers a performance edge over single fan configurations by covering a larger surface area without increasing electrical draw.
Factory Bracket Alignment for Straightforward Installation
Designed to match the original radiator support bracket locations on 1970-1981 Camaro and 1978–1988 G Body frames, this unit installs without altering mounts or frame rails for 4L60E and 4L80E automatic transmissions. Coolant lines follow the stock routing along the F Body frame rail, so there is no need for custom hose extensions or adapter fittings. This direct fit approach can cut installation time to a matter of hours, allowing builders to turn their attention to engine calibration instead of fabrication. By preserving the factory mounting structure, the assembly maintains the intended crash integrity and alignment. The broad compatibility of this solution makes it a reliable choice for a wide range of Chevy, Pontiac, Oldsmobile, and Buick models during an LS or LT swap.
