1973-1977 A-Body LS Radiator with Fans for Automatic Transmissions
Anyone installing an LS engine into a 1973 to 1977 A Body with an automatic transmission will value how the 1973 to 1977 A Body LS Radiator (Automatic Trans) with Fans stabilizes coolant temperature in traffic and at speed. The assembly features 100% TIG welded tanks and core, constructed from high quality aluminum, coupled with dual high performance electric fans in stock shroud positions. It fits Chevrolet Chevelle, Monte Carlo, El Camino, Laguna, GMC Sprint, Buick Regal, Oldsmobile Cutlass and Pontiac Grand Am or Grand Prix by using factory mounting points and coolant hose connections. Available in bare aluminum or black epoxy finish, each radiator is pressure tested and includes integrated transmission cooler ports. Made in USA at Michigan assembly plant; allow longer lead times due to slowed production.
Precise Cooling for A Body LS Applications
The 1973 to 1977 A Body LS radiator for automatic transmission equipped cars brings targeted temperature control to your classic ride. Dual high performance fans are installed at the factory to ensure even air flow across the entire core surface, keeping coolant within optimal range under varied driving demands. By maintaining stable temperatures, the system prevents hot spots that can degrade seals or reduce engine efficiency. Manufactured in the USA, this unit meets stringent quality benchmarks and retains full compatibility with GM LS powerplants common to A Body conversion projects.
Rugged Aluminum Structure
Constructed entirely from premium aluminum, both tanks and core undergo 100 percent TIG welding for a uniform seam that stands up to thermal cycles and vibration. The metal resists corrosion far better than traditional copper or brass, extending service life and reducing the risk of coolant leakage over time. Lightweight yet robust, this all-metal assembly lowers front end mass compared to heavier designs, delivering a slight handling benefit and less stress on mounting points. Every joint is visually inspected and pressure tested to guarantee leak free operation right out of the box.
Seamless MuscleRods Integration
Designed to mate directly with MuscleRods mounting hardware, this radiator aligns engine placement and transmission angle precisely for correct drive line geometry. The finished package preserves factory style hose routing and simplifies installation by eliminating the need for custom brackets or fan shrouds. Cooling fan connectors and mounting ears match the MuscleRods kit dimensions, so installers save time and avoid guesswork. Whether you are swapping an LS mill into a 1974 or a 1977 model, this radiator offers a drop in solution that supports both engine performance and drivetrain longevity.
This radiator is pressure tested and made in the USA for reliable LS swap cooling. For the same radiator but without fans, consider our 1973-1977 A-Body LS Radiator (Automatic Transmission) Without Fans.
