LS Radiator with Fans for 1973-1977 A-Body Automatic Transmissions
Anyone tackling an LS engine swap into a 1973-1977 Chevy A-Body with an automatic transmission will find that the 1973-1977 A-Body LS Radiator (Automatic Trans) with Fans addresses the common challenge of maintaining stable coolant temperatures under varied load. A carefully designed TIG welded aluminum core and integrated fans in original mounting points deliver consistent airflow across the entire heat exchanger. Fitting models like Chevelle Monte Carlo El Camino and Laguna, this radiator preserves factory coolant routing and uses stock mounting points to avoid custom chassis work. Each unit is pressure and leak tested to confirm reliable performance in traffic or on the track.
Precision TIG Welding for Aluminum Radiator Durability
The core and tanks of this LS radiator are assembled using a 100 percent TIG welding process that creates a seamless bond without filler material. By fusing high quality aluminum at precise temperatures, each joint resists leaks and endures repeated thermal cycles that occur during stop and go traffic or spirited driving. The result is a structure that maintains integrity under coolant pressure spikes and rapid temperature changes, while keeping overall weight lower than cast or brazed alternatives. Every weld is inspected and pressure tested to confirm long term resilience before the radiator leaves the factory.
Dual Fan Airflow System for Stable Temperatures
A matched pair of electric fans is mounted in the original shroud positions to ensure balanced airflow across the entire heat exchanger surface. Controlled by coolant temperature sensors, these fans engage only when needed to eliminate hotspots and maintain a steady heat rejection rate during idling or heavy load conditions. Their even distribution protects both the engine coolant passages and the integrated transmission cooler, safeguarding the automatic gearbox from excess heat. This intelligent arrangement supports consistent operating temperatures whether cruising on the highway or crawling through city traffic.
Corrosion Resistance with Bare Aluminum or Black Epoxy Finish
Choose a natural aluminum appearance that benefits from the metal's self limiting oxide layer or opt for a black epoxy coating applied prior to assembly for complete coverage. The pre coating process guarantees that tanks, core fins and welded seams receive a continuous protective barrier against moisture, road chemicals and debris. Both finishes preserve the radiator's thermal conductivity while extending service life in coastal or winter driving environments. This focus on corrosion defense maintains reliable cooling performance and keeps the unit looking factory fresh over years of use.
Direct Bolt In Installation for 1973 to 1977 A Body Vehicles
This radiator drops neatly into 1973-1977 Chevy and GMC A Body models, including Chevelle, Monte Carlo, El Camino and Laguna, by using the stock mounting points and hose connections. No frame modifications or custom brackets are required, so the lines from the engine and automatic transmission slide directly into place without bending or kinking. That precise fitment preserves original chassis geometry, under hood clearance and coolant routing while reducing installation time. The integrated transmission cooler ports align perfectly with factory lines, ensuring reliable fluid flow from day one.
