Performance Radiator for Chevrolet Chevelle (1968-1973)

High-Capacity Performance Radiator for 1968-1973 Chevrolet Chevelle

What it Does: Replaces the restrictive factory cooling system with a 3-row aluminum core and dual 12-inch electric fans to drastically lower coolant temperatures under heavy load.

The Stock Chevelle Heat Soak Problem

The original copper-brass radiators equipped in GM A-Body vehicles suffer from inherent heat soak and poor thermal efficiency, especially when paired with modified Small Block (SBC) or Big Block (BBC) Chevy engines. The factory mechanical fan and standard core design fail to provide adequate airflow during idle or stop-and-go traffic. This lack of low-speed airflow leads to dangerous coolant temperature spikes, vapor lock, and potential head gasket failure under high-performance driving conditions.

The Engineering Solution

This cooling package replaces the outdated OEM unit with a 3-row aluminum racing-spec radiator core, maximizing surface area and thermal dissipation. Aluminum construction sheds heat faster than traditional brass while reducing front-end chassis weight. The integrated aluminum shroud ensures the dual 12-inch, 10-blade electric fans—each pulling up to 1730 CFM at 2,250 RPM—draw air evenly across the entire 16.85" x 28.25" core, eliminating static hot spots. A built-in transmission oil cooler (φ32*215*G1/4) stabilizes fluid temperatures for both automatic and manual applications. Operating efficiently at a 12.70 amp draw per fan, this system provides consistent, on-demand airflow regardless of engine speed.
