Performance Radiator for Pontiac GTO (1968-1973)

High-Capacity Performance Radiator for 1968-1973 Pontiac GTO

Replaces the aging factory brass-and-copper radiator with a high-efficiency aluminum core and dual-fan setup to eliminate heat soak during high-rpm driving and heavy traffic.

The Stock GM A-Body Cooling Problem

The factory GM A-Body cooling system relied on traditional brass and copper construction with inefficient tube spacing. Over decades, these OEM cores suffer from solder bloom, internal scaling, and degraded fin-to-tube contact, drastically reducing thermal transfer efficiency. Paired with the immense engine bay heat soak generated by high-displacement Pontiac V8s, the factory mechanical clutch fan struggles to pull sufficient airflow at low RPMs, resulting in dangerous coolant temperature spikes during heavy traffic or aggressive driving.

The Engineering Solution

This complete cooling overhaul features a TIG-welded, 3-row aluminum core engineered to maximize cooling surface area and coolant fluid agitation. Aerospace-grade aluminum offers vastly superior heat dissipation compared to stock brass while significantly cutting front-end weight. The system utilizes a precise aluminum shroud housing dual 12-inch, 10-blade electric fans pulling a combined 3,460 CFM (at 2,250 RPM and 12.7 amps per fan). This active thermal management guarantees high-velocity airflow through the core even at idle. Designed for direct saddle mounting, it includes a built-in internal transmission oil cooler suitable for both automatic and manual configurations.
