LS and LT Engine Swap Radiator for 1968-1972 A-Body and 1970-1972 Monte Carlo
If your 1968 through 1972 A-Body or 1970 through 1972 Monte Carlo project calls for reliable heat management, this radiator with dual fans is built to handle the extra thermal load of an LS or LT engine in a manual transmission setup. It features a TIG welded aluminum core that bolts directly to original brackets and aligns with factory hose routing to maintain firewall clearance without modifying sheet metal. The quiet fans engage at a preset coolant temperature to pull air evenly across the entire core and prevent heat spikes during urban traffic or spirited driving sessions. Together these details deliver steady engine temperatures and a truly plug and play fit that simplifies installation for custom muscle car swaps.
Precision TIG Welding and Aluminum Core Strength
Every radiator and end tank is united by tungsten inert gas welding to form a continuous, pore free bond that resists leaks under repeated thermal cycling. TIG welding delivers precise control over heat input, preventing distortion of the high quality aluminum while creating strong, fatigue resistant seams. Aluminum's excellent thermal conductivity ensures rapid heat transfer from coolant to fin array, while its light weight helps maintain balanced vehicle handling. This construction method yields a durable heat exchanger that can endure the elevated demands of LS or LT engine swaps without compromise.
Optimized Dual Fan Airflow Management
Two high capacity electric fans activate at a preset coolant temperature threshold to draw air uniformly across the full face of the core. This approach prevents temperature spikes in stop and go traffic or during steep climbs, protecting internal engine components from overheating. The fans are engineered to run quietly and pull minimal current from the charging system, so they do not overtax wiring or alternator capacity. Consistent airflow under varying driving conditions translates directly to stable engine temperatures and improved reliability.
Factory Mounting and Hose Routing Preserve Clearance
This radiator mounts directly to the original brackets on 1968–1972 A-Body frames and 1970–1972 Monte Carlo chassis, aligning with factory hose paths to keep firewall clearance intact. By retaining the stock mounting points, installers avoid time consuming modifications to sheet metal or brackets. The plug and play design simplifies fit up for both home builders and professional shops, ensuring a precise installation every time. Maintaining the manufacturer's layout also prevents interference with surrounding components, which is critical in a manual transmission setup.
Durable Bare and Epoxy Coating Options
Choose the classic bare aluminum finish, which forms a natural, self healing oxide layer that resists corrosion over time, or select the black epoxy coating for added protection against moisture and road debris. Both options adhere directly to the aluminum substrate without reducing thermal rejection, so cooling performance remains unchanged. The epoxy option delivers enhanced chemical and impact resistance, while the untreated surface offers minimal weight and intrinsic corrosion defense. Either finish preserves the radiator’s integrity and appearance through years of use.
Count on consistent temperature control even without the fans. For the same radiator but without fans see 1968-1972 A-Body and 1970-1972 Monte Carlo Radiator (Manual Transmission) Without Fans.
