1968-1972 A-Body and Monte Carlo LS and LT Radiator with Fans for Manual Transmissions
When fitting an LS or LT engine into a 1968 to 1972 A Body or 1970 to 1972 Monte Carlo with a manual transmission the stock cooling system often struggles to maintain engine temperatures under load. Designed as a direct replacement this radiator uses factory mounting points and stock hose ports to preserve firewall clearance and eliminate custom fabrication. Pairing a TIG welded aluminum core with dual high capacity fans the assembly draws air evenly across the full surface for reliable heat rejection in both traffic and spirited driving. Mounting points align with original brackets so builders can install without adapters or new hard lines making it an ideal choice for LS or LT conversions.
Precision Aluminum Core with TIG Welds
The radiator core and end tanks are assembled using TIG welding to fuse high-quality aluminum with pinpoint heat control. This technique produces uniform seams that eliminate gaps and guard against leaks as temperatures cycle under load. With flat fin alignment maintained throughout fabrication, coolant flows smoothly and heat is transferred rapidly from liquid to metal surfaces. The result is a durable heat exchanger that sustains steady performance across the demands of LS and LT engine applications.
Optimized Airflow from Dual Electric Fans
Two high-capacity electric fans are positioned for even pull across the entire radiator face, ensuring hotspots do not develop during slow traffic or spirited driving. Each fan engages automatically when coolant reaches a set threshold, maintaining consistent temperature without manual intervention. Quiet operation and modest electrical draw keep alternator load in check while still delivering robust cooling. Builders benefit from standard GM wiring compatibility for simple set up and fine tuning of activation points.
Direct Bolt In Fit for Manual Transmission Models
Engineers designed mounting points and hose ports to match original factory locations on 1968-1972 A bodies and 1970-1972 Monte Carlo chassis. This plug in configuration prevents interference with steering linkages, hard lines or firewall components. By retaining stock routing, installers avoid custom brackets or cutting and bending hoses. The result is a streamlined swap process that reduces labor time and minimizes the chance of alignment errors in home or professional shops.
Choice of Bare or Epoxy Coating for Lasting Protection
Owners may select classic bare aluminum, which forms a thin oxide layer naturally, or opt for a black epoxy finish to bolster resistance against moisture and road debris. Both options preserve efficient heat rejection, so thermal performance remains unaffected. The epoxy layer provides an extra barrier to chemical exposure and impacts, while the untreated core relies on aluminum's inherent corrosion resistance and minimal added weight. Each finish extends service life and retains a clean appearance over years of use.
