Performance Radiator for Oldsmobile Cutlass (1997-1999) 3.1L Automatic

Direct-Fit All-Aluminum 3-Row Performance Radiator for 1997-1999 Oldsmobile Cutlass

Replaces the fragile factory plastic-tank cooling unit with an all-aluminum 3-row crossflow core to maximize thermal rejection and prevent cooling system failure.

The Stock Cutlass Plastic Tank Vulnerability

The factory radiator on the N-body Cutlass utilizes a single-row core crimped to molded plastic end tanks. Over thermal cycles, these plastic tanks become brittle, causing hairline fractures at the inlet and outlet necks. Under sustained operating temperatures, the OEM core restricts fluid throughput, exacerbating coolant breakdown and risking blown head gaskets on the GM 3100 V6.

The Engineering Solution

Engineered from 100% TIG-welded aircraft-grade aluminum, this 3-row racing core significantly increases coolant capacity and surface area dissipation. Precision-brazed aluminum tubes paired with high-efficiency louvered fins optimize crossflow heat transfer without restricting front-end airflow. It features an integrated automatic transmission oil cooler, maintaining proper line pressures and fluid longevity under load.
