1968-1972 A-Body and Monte Carlo Auto Trans Radiator for LS and LT Swaps
When tackling an LS or LT powerplant swap into a 1968 to 1972 A-Body or Monte Carlo, ensuring reliable cooling under the demands of an automatic transmission is essential. This radiator mounts directly to original Chevelle, Skylark, Cutlass, GTO, LeMans and El Camino points without cutting or welding and its design clears popular 4L60E and 4L80E applications. Its full aluminum core combined with a 400 liter per hour water pump maintains under hood temperatures even during spirited driving. With precise alignment and direct-fit construction, enthusiasts preserve a tidy engine bay while coolant flow stays rock solid on extended highway runs.
All Aluminum Core for Rapid Heat Rejection
The radiator's full aluminum core delivers exceptional thermal conductivity, moving heat away from LS and LT powerplants even when output peaks. Its open cell structure increases surface area for coolant to air contact, so temperature spikes are kept in check during spirited driving or heavy towing. Choosing a bare finish preserves the classic engine bay appearance and allows for easy visual inspections of tube and fin integrity. An optional black epoxy coat is available for those who need extra protection against road debris and environmental corrosion without sacrificing cooling efficiency.
Direct Mount Design for Classic GM A Body Models
Engineers crafted this radiator to bolt directly into original mounting points on 1968 through 1972 A Body vehicles and 1970 through 1972 Monte Carlo frames. No cutting, welding, or bracket fabrication is required, so installers retain stock crossmember, tunnel, and hose routing. The precise clearance accommodates popular automatics such as the 4L60E and 4L80E, avoiding interference with transmission housings or accessories. This attention to fitment detail reduces installation time and preserves a factory-styled engine bay layout.
400 Liter per Hour Pump Ensures Consistent Flow
At the heart of this cooling system lies a water pump rated at 400 liters per hour, designed to maintain robust coolant circulation under sustained load. By keeping fluid moving steadily, it prevents localized hotspots that can lead to boil-over or engine knock. This consistent flow is especially important for LS and LT swaps equipped with forced induction, where stable coolant delivery supports reliable power output and component longevity. The pump and core work in harmony to deliver controlled temperatures across a wide range of driving conditions.
Domestic Assembly Backed by Rigorous Quality Control
Every radiator is assembled in the USA using premium domestic aluminum, ensuring material consistency and traceable production standards. Each unit undergoes multiple quality checks, including pressure testing and weld inspection, to confirm leak-free performance and structural integrity. Local manufacturing allows for tighter production tolerances, which translates into uniform tube spacing and fin alignment for maximum thermal efficiency. This level of craftsmanship not only supports reliable everyday use but also enhances resale value for classic vehicle restorations.
