Radiator for Buick Regal (2014-2016) 2.0L

All-Aluminum Performance Radiator for 2014-2016 Buick Regal

What it Does: The all-aluminum radiator replaces the failure-prone composite factory cooling unit on the 2014-2016 Regal to maximize thermal heat dissipation and prevent coolant loss under sustained boost conditions.

The Stock Buick Regal Plastic Tank Fatigue and Crimp Seam Failure

The OEM cooling unit installed in the Epsilon II platform relies on crimped glass-filled nylon end tanks bound to an aluminum core with synthetic rubber o-rings. Over repeated thermal cycles driven by the forced-induction LTG 2.0L engine—which generates continuous cylinder head heat and cooling system operating pressures above 15 psi—the polymer tanks dry out, harden, and micro-fracture. Thermal expansion variances between plastic and aluminum eventually breach the crimp tabs, precipitating rapid coolant loss, dangerous overheating, and warped cylinder heads.

The Engineering Solution

This high-efficiency replacement is fabricated entirely from aircraft-grade aluminum, utilizing fully TIG-welded tanks to eliminate plastic construction and crimped gasket interfaces permanently. The core is constructed with controlled-atmosphere furnace-brazed tubes and high-density multi-louvered cooling fins to optimize laminar airflow heat transfer. By decreasing fluid restriction and eliminating factory thermal choke points, this radiator maintains stable coolant temperatures during aggressive throttle inputs and hot-weather operation.
