LS and LT Radiator for 1968-1972 A-Body and 1970-1972 Monte Carlo Manual Transmissions
When you retrofit an LS or LT engine into a classic 1968 to 1972 A body or 1970 to 1972 Monte Carlo manual transmission chassis, reliable cooling is essential to keep operating temperatures in check. Featuring a TIG welded aluminum core and matching tanks, this radiator resists leaks and withstands engine vibration for consistent performance under load. Installation is simplified by inlet and outlet ports that follow the factory hose routing and fasten to original support points without custom brackets. Its all aluminum construction facilitates rapid heat rejection while preserving hood clearance for a precise fit in the engine bay.
Precision TIG Welded Aluminum Core and Tanks
Every joint in this radiator is crafted using TIG welding to fuse the aluminum core to its tanks without the need for filler metals. This process delivers uniform material thickness across all welds, eliminating weak spots that can develop under engine vibration. As a result, the assembly resists leaks even in demanding driving conditions and simplifies routine inspections, since any discontinuity in the weld bead is easy to detect. Built in the USA from high quality aluminum, the radiator offers exceptional fatigue resistance and a long service life while preserving the purity of the coolant path.
All Aluminum Construction for Rapid Heat Dissipation
The core and tanks are formed entirely from premium aluminum prized for its thermal conductivity and corrosion resistance. This mono-metal design promotes fast heat transfer from coolant to ambient air, maintaining stable engine temperatures during spirited street runs or extended track sessions. A precision tube and fin layout ensures uniform fluid distribution and maximizes surface area exposure, preventing hotspots that could degrade performance or damage seals. At the same time, the lightweight assembly contributes to more responsive throttle inputs without sacrificing structural rigidity.
Classic Bare Aluminum and Black Epoxy Finish Options
Two finish selections let you tailor protection and style to your restoration or custom build. The natural bare aluminum finish showcases the core's craftsmanship and delivers maximum passive heat flow, while the black epoxy coat adds a durable barrier against moisture, road debris, and chemicals. Neither option impairs thermal performance, and both undergo rigorous adhesion and coverage testing to ensure consistent durability in harsh environments. Choosing between the finishes allows you to balance visual appeal with long term resistance to pitting and corrosion.
Direct Fit Installation for 1968 to 1972 A Body and Monte Carlo Vehicles
Designed specifically for manual transmission configurations in 1968 to 1972 A Body cars and 1970 to 1972 Monte Carlo models, this radiator attaches directly to factory support points without custom brackets. Inlet and outlet ports align precisely with the original hose routing, preserving hood clearance and the vehicle's structural integrity. The bolt-on design streamlines the engine swap process, eliminating time spent on fabrication and ensuring that service access remains straightforward for coolant changes or core inspections. This direct installation maintains the chassis geometry envisioned by the automaker while providing modern cooling capacity for LS or LT powerplants.
