LS and LT Swap Auto Trans Radiator for 1968-1972 A-Body Vehicles
Enthusiasts tackling LS or LT swaps in classic GM A-Body cars will appreciate how the 1968 to 1972 A-Body and 1970 to 1972 Monte Carlo Radiator (Auto Trans) keeps coolant temperatures in check even under heavy load. It installs into original mounts on Chevelle, Skylark, Cutlass, GTO, LeMans and El Camino models without cutting or welding and provides clearance for 4L60E and 4L80E transmissions. With a durable aluminum core paired to a 400 liter per hour water pump, this radiator sustains efficient heat rejection while fitting seamlessly within existing engine bay layouts.
Superior Heat Transfer with Bare Aluminum Core
The radiator's all-aluminum core delivers exceptional thermal conductivity, rapidly moving heat away from the engine under demanding conditions. Its lightweight structure reduces front-end mass while providing structural strength that resists vibration and stress. Opting for a bare finish preserves the classic engine bay look and simplifies visual inspection for corrosion or damage. For users seeking extra defense against road salts and airborne debris, the optional black epoxy coat adds a durable, protective layer without hindering heat rejection.
Seamless Integration into 1968 to 1972 A Body Framework
Engineers designed this radiator to match factory mounting points on Chevelle, Skylark, Cutlass, GTO, LeMans and El Camino models from 1968 to 1972. No cutting or welding is required, allowing installers to retain the original crossmember, tunnel and hose routing. The precision fit also clears popular automatics such as the 4L60E and 4L80E, eliminating interference with the transmission or accessories. This attention to detail reduces installation time and ensures a clean, stock-looking engine bay.
High Volume Pump Performance for Sustained Flow
At the heart of this cooling solution is a water pump rated at 400 liters per hour, engineered to maintain robust coolant circulation even when output is pushed to the limit. By preventing localized hotspots, the system guards against boil-over and keeps engine temperatures within optimal range during highway runs or track sessions. This flow capacity is especially critical for LS and LT powerplants equipped with turbos or superchargers, where stable coolant delivery supports consistent power output. The pump and core pairing work in concert to deliver reliable thermal management session after session.
American Craftsmanship for Reliable Durability
Built in the USA, each radiator undergoes stringent quality checks to uphold tight tolerances and uniform weld integrity. Sourcing domestic aluminum ensures consistent material properties, while local assembly supports precise routing of tubes and fins for maximum efficiency. This level of craftsmanship contributes to long lasting performance and can enhance the vehicle's resale appeal. Enthusiasts benefit from a product backed by regional support and proven reliability on both street and strip applications.
