1973-1977 A-Body LS Radiator with Fans for Manual Transmission
Swapping an LS engine behind a manual transmission into a 1973-1977 A Body often reveals that the stock radiator can struggle to manage rising coolant temperatures under load. This 1973-1977 A Body LS Radiator (Manual Trans) with Fans addresses that challenge with a TIG welded aluminum core and dual electric fans that activate based on coolant temperature readings. Installed using original hose connections and factory mounting points it fits Chevelle, Monte Carlo, El Camino and other A Body models without modification. Corrosion resistant construction and solid welds maintain constant coolant flow whether idling in traffic or pushing the engine hard at the track.
Precision TIG Welding for Core Durability
Each radiator core and tank joint in this assembly is crafted using a precise TIG welding process that creates uniform bead patterns along aluminum surfaces. This method ensures consistent wall thickness and eliminates flow restrictions across the fin stack, promoting stable coolant circulation under sustained engine load. Aluminum's innate thermal conductivity combines with rigid welds to transfer heat rapidly from coolant to the core, preventing hotspots even during extended track sessions. The reinforced structure resists shock and vibration common in road use, securing long lasting performance for your LS swap.
Adaptive Dual Fan Control for Efficient Cooling
This radiator includes two electric fans that switch on independently according to coolant temperature, delivering variable airflow when and where it is needed most. At idle or in traffic a single fan operates to maintain engine temperature without drawing excessive electrical power, while both fans engage under heavy load to maximize heat rejection. The integrated shroud holds fan blades close to the core to ensure uniform air distribution across every row of fins. Prewired connectors and supplied clips streamline the electrical hookup, avoiding the need for custom splicing or brackets.
Direct Fitment with Factory Mounting Points
Designed for a bolt in swap, this radiator uses original hose end locations and factory mounting tabs to match 1973 to 1977 A Body chassis architecture. Installers can reuse stock plumbing and bracketry, which preserves underhood packaging and accessory clearances without requiring frame or firewall modifications. This direct fitment approach reduces labor time and simplifies routine service tasks like coolant flushes or fan replacements. Wire harnesses and fan connectors align with factory outlets so installers can complete the job with basic hand tools.
Corrosion Resistant Aluminum Finish Options
Choose between a bright bare aluminum surface or a rugged black epoxy coating tailored to protect against moisture and road debris. The epoxy layer bonds tightly to the metal, inhibiting corrosion and abrasion in demanding environments while still allowing easy cleaning and maintenance. Uncoated radiators can be refreshed with standard cleaners to preserve their bright appearance and thermal efficiency. Both choices deliver consistent heat rejection and durability, ensuring this radiator remains a reliable component in your LS equipped A Body.
