LS and LT Radiator for 1970-1981 F-Body and 1978-1988 G-Body Vehicles
Swapping an LS or LT motor into a 1970 to 1981 Camaro or 1978 to 1988 G Body with a manual transmission demands reliable coolant management whether the vehicle is idling in traffic or tackling track laps. This radiator features a TIG welded aluminum core paired with cast aluminum tanks and dual high flow fans to maintain steady coolant temperatures in stop-and-go traffic or during spirited runs. Mounting brackets and hose connections align precisely with factory points on both F Body and G Body chassis to preserve under hood clearance and simplify installation without custom tubing. Customers can choose a natural finish for passive oxidation protection or a black epoxy coat for moisture and road chemical resistance giving lasting service and a clean appearance under any driving condition.
Precision TIG Welding Enhances Core Integrity
The radiator core and tanks are fused using tungsten inert gas welding, a process prized for its deep metal fusion and minimal distortion. By applying concentrated heat only where needed, TIG welding prevents small fissures that can develop under repeated heat cycles, ensuring each joint remains leak free through daily driving or spirited track sessions. Constructed entirely from premium aluminum, the heat exchanger achieves a high strength to weight ratio while speeding thermal transfer from coolant to fins. Domestic fabrication of each unit allows for strict quality control at every stage, so weld consistency and surface finish meet rigorous build standards. The result is a robust assembly that resists fatigue and maintains service integrity over many seasons of use.
Dual Fan Configuration for Balanced Airflow
This cooling solution pairs two electric fans directly against the core face to generate uniform airflow when natural movement is limited. Splitting the workload trims electrical draw per motor and reduces audible output compared to a single larger blower, making for a quieter cabin during idle periods or tight traffic conditions. Each fan is governed by a temperature sensing switch that activates only when coolant temperature rises above the ideal band, preventing wasted energy when airflow from vehicle motion suffices. Even distribution of moving air across the core eliminates hot spots, so coolant never exceeds safe limits whether cruising on the highway or navigating winding back roads. This balanced design protects engine components from heat stress without placing undue strain on the charging system.
Tailored Fitment for F Body and G Body Chassis
Designed for 1970 to 1981 Chevrolet Camaro and Monte Carlo plus 1978 to 1988 G Body variants, this radiator lines up precisely with original frame mounts and factory hose ports. By matching the 1970 era block to frame clearance and preserving stock hood height, no special brackets or custom tubing are required to complete a swap. The drop in nature of this unit streamlines installation, allowing professional shops and home builders alike to secure the core and connect plumbing in minimal steps. Proper alignment prevents contact with inner fender panels, power steering lines, or alternator housing, reducing the risk of wear or vibration noise. As a result, underhood space remains unchanged and the classic engine bay layout retains its authentic presentation.
Selective Finish Options for Corrosion Protection
Customers choose between an untreated aluminum surface or a black epoxy barrier to suit aesthetic and environmental needs. The bare metal option quickly develops a thin oxide film that actively resists corrosion while maintaining maximum heat transmission. Alternatively, the epoxy layer adds moisture and chemical resistance, safeguarding against road salts or frequent wash cycles. Both finishes shed dirt and debris easily from fin surfaces, simplifying maintenance and preserving cooling performance. This flexibility ensures the radiator retains its structural integrity and underhood appearance across a wide range of climates and driving conditions.
