1968-1972 A-Body and 1970-1972 Monte Carlo Radiator for LS and LT Engine Swaps (Auto Trans)
Ready to mount an LS or LT powerplant with an automatic transmission in your 1968 through 1972 A Body or Monte Carlo project? This radiator bolts into original frame locations on Chevelle, Skylark, Cutlass, GTO, LeMans and El Camino chassis without cutting or welding and provides clearance for 4L60E and 4L80E transmissions. It pairs a full aluminum core with a 400 lph water pump to maintain stable coolant flow under sustained load or spirited highway driving. Engineers designed each unit in the USA for reliable fitment, tidy hose routing and consistent cooling performance on both stock and supercharged engines while lightweight construction reduces front end mass.
Optimized Aluminum Core for Consistent Thermal Management
The radiator's core is crafted from high quality aluminum to take advantage of the metal's excellent heat transfer properties and inherent corrosion resistance. Multiple rows of precision formed tubes and fins create an open cell structure that maximizes surface area and airflow, ensuring rapid dissipation of heat generated by LS and LT engines. A 400 lph water pump maintains steady coolant circulation across the entire core during sustained load or spirited driving, preventing rapid temperature spikes. By keeping engine temperature within its ideal range, the design minimizes stress on seals and gaskets, helping to extend service life of critical components. The combination of durable construction and lightweight material also reduces front end mass without compromising strength.
Direct Fit to Classic A Body and Monte Carlo Frames
Engineers designed this radiator to bolt into the original mounting points of 1968-1972 A Body and 1970–1972 Monte Carlo frames without any cutting or welding. This direct installation preserves the factory crossmember location and tunnel shape, simplifying hose routing and maintaining a clean engine bay appearance. Built-in clearance for popular automatic transmissions including 4L60E and 4L80E ensures unobstructed space around the bell housing and prevents interference with accessories. Installers benefit from reduced alignment concerns and shorter assembly times, turning a complex swap into a straightforward upgrade. A tidy layout under the hood enhances both functionality and show quality.
Custom Finish Options for Enhanced Durability and Appearance
Choose between a natural bare aluminum finish or a protective black epoxy coating to suit your build and environmental needs. The bare surface highlights the precision core construction and allows for quick visual inspection of tubes and fins, making it easier to detect any early signs of wear or damage. The epoxy option adds a tough barrier against road debris, moisture and chemical contaminants, which is especially valuable in coastal or winter climates. Both finishes maintain the same cooling efficiency and flow characteristics, ensuring consistent performance. This flexibility lets you coordinate under hood styling without sacrificing thermal capability.
United States Assembly Ensuring Quality and Reliability
Every radiator is assembled and tested in the United States using domestically sourced aluminum for full traceability of material properties. During production each unit undergoes pressure testing to confirm leak-free operation and visual inspection of brazed joints to verify structural soundness. Strict manufacturing tolerances guarantee uniform tube spacing and precise fin alignment, which are essential for effective heat transfer. Local assembly also enables rapid response to quality concerns and ensures compliance with industry standards. The result is a cooling upgrade you can trust to deliver consistent performance drive after drive.
