1973-1977 A-Body LS Radiator with Fans for Auto Transmissions
When fitting an LS powerplant into a 1973 to 1977 Chevy A-Body with an automatic transmission the stock radiator often struggles to maintain coolant flow and temperature stability risking engine and transmission wear in traffic or track use. The 1973 to 1977 A-Body LS Radiator (Automatic Trans) with Fans combines a TIG welded aluminum core and tanks with a pair of electric fans installed in the factory locations for consistent airflow and to reduce hotspots. Designed for direct fit on Chevelle Monte Carlo El Camino Laguna and other A-Body vehicles this unit preserves original coolant line routing and mounting points so no chassis modifications are required. Every radiator undergoes pressure and leak testing to ensure durability and reliable performance under varied driving loads.
Seamless TIG-welded Aluminum Core and Tanks
The radiator core and tanks are joined with a TIG-welded process that creates a uniform bond without filler metal. This technique produces a leak resistant seal capable of withstanding repeated thermal cycles and pressure spikes common in stop and go traffic. Aluminum's natural thermal conductivity works in concert with the precision welds to reject heat rapidly, reducing load on the cooling system during spirited driving or highway cruising. At the factory each assembly is pressure tested to confirm structural integrity and coolant containment before it ships to ensure reliable performance under varied operating conditions. The combination of high quality aluminum and TIG-welded strength keeps overall weight lower than traditional designs while delivering robust durability.
Strategic Dual Fan Placement for Consistent Cooling
A pair of electric fans is mounted in the original fan shroud locations to deliver balanced airflow across the entire heat exchanger surface. These fans engage based on coolant temperature, eliminating hotspot formation during idling or slow traffic and boosting core efficiency under heavy load on the track. Their synchronized operation spreads cooling air evenly over both the radiator core and the integrated transmission cooler, safeguarding the automatic gearbox from excessive heat. By running only when needed, the system conserves electrical power without sacrificing temperature control in harsh summer conditions. This intelligent fan arrangement ensures stable engine and transmission temperatures regardless of driving style.
Classic Bare or Epoxy Coating Defends Against Corrosion
Choose the natural finish of bare aluminum to take advantage of the metal's self protective oxide layer or upgrade to a black epoxy coating for enhanced resistance to moisture and road debris. The epoxy is applied before assembly to guarantee continuous barrier coverage across tanks, core fins and internal passages. This pre assembly treatment prevents undercoating voids and ensures that every welded seam receives the same level of protection. As a result, the radiator maintains a factory fresh appearance and extends its service life even in coastal regions or on salted winter roads. Both finishes preserve thermal efficiency while guarding against the onset of corrosion.
Direct Bolt in Fit for 1973 to 1977 A Body Installations
This radiator installs using the stock mounting points and aligns with the factory coolant lines on Chevelle, Monte Carlo, El Camino, Laguna and other A Body models from 1973 through 1977. No frame modifications or custom brackets are required, so installation time is minimized and the risk of fitment error is reduced. Transmission cooler lines plug directly into the integrated cooler ports, preserving factory routing and preventing kinks that can impede fluid flow. The drop in design safeguards original chassis geometry and maintains under hood clearance for other accessories. Together, these features deliver a straightforward installation that keeps your classic vehicle looking and performing as intended.
