1973-1977 A-Body LS Radiator with Fans for Automatic Transmissions
Whether you're navigating traffic or cruising on freeways this 1973 to 1977 A Body LS radiator is built to handle the demands of an LS engine and automatic transmission swap in Chevelle, Monte Carlo, El Camino and other A Body classics. Featuring a TIG welded aluminum core and dual electric fans mounted to the factory locations it promotes uniform coolant circulation and eliminates hot spots across the full tear drop profile of the heat exchanger. Installation requires no frame changes or custom brackets since the precise fit retains stock mounting points and original chassis geometry. With consistent cooling performance on city streets or longer drives it protects both engine and transmission components in all driving conditions.
Precision TIG Welded Aluminum Core Integrity
The core and tanks of this radiator are joined with TIG welding, which fuses high quality aluminum components without the need for filler material. This technique forms a continuous, homogenous bond that resists leaks even under repeated thermal cycling. The choice of aluminum delivers superb thermal conductivity while keeping overall weight low, ensuring heat generated by an LS engine and automatic transmission is expelled efficiently. Each unit is inspected for weld consistency and pressure tested to guarantee long lasting coolant containment and reliable performance in all driving scenarios.
Dual Electric Fans for Balanced Cooling Performance
Featuring two high performance electric fans mounted in factory locations, this radiator maintains consistent airflow across the entire heat exchanger. The fans operate based on coolant temperature, engaging during urban driving conditions or spirited runs on the track to prevent hotspots. Their dual arrangement spreads cooling air evenly and reduces strain on the engine and transmission cooler, while limiting electrical draw by running only when necessary. This strategy ensures stable operating temperatures in slow-traffic situations and sustained highway cruising alike.
Direct Factory Fitment for 1973 to 1977 A-Body Models
Engineered specifically for 1973–1977 Chevy Chevelle, Monte Carlo, El Camino and related A-Body platforms, this radiator bolts directly into original mounting points without frame alterations or custom brackets. By preserving the stock chassis geometry and existing coolant line routing, installation time is minimized and alignment issues are eliminated. Transmission cooler hoses connect seamlessly to the automatic transmission, maintaining proper clearances and ensuring a precise fit that upholds the vehicle's handling characteristics.
Versatile Finishes for Extended Corrosion Protection
Select either a natural bare aluminum finish or a resilient black epoxy coating to suit both aesthetic preferences and environmental challenges. The bare option allows for easy inspection of weld integrity while benefiting from aluminum's natural oxide layer. The black epoxy provides an added barrier against moisture, road debris and brake dust, protecting external tanks and core surfaces. Both coatings are applied prior to assembly to ensure complete coverage of internal passages and deliver durable corrosion resistance for years of dependable service.
