Radiator for Acura Legend (1991-1995) 3.2L

High-Efficiency All-Aluminum Radiator for 1991-1995 Acura Legend

What it Does: The all-aluminum performance radiator replaces the failure-prone plastic-tank factory cooling unit on the 1991-1995 Acura Legend to eliminate coolant leaks and optimize heat dissipation under load.

The Stock Acura Legend Cooling System Weakness

Factory cooling systems on the second-generation Acura Legend utilize an OEM radiator built with crimped nylon-composite plastic end tanks mating to an aluminum core. Over decades of thermal expansion and contraction, these aged polymer tanks become brittle, routinely developing hairline stress fractures around the upper hose inlet neck and failing along the crimped tank-to-core o-ring seals. In the longitudinally mounted C32A V6 engine, cooling failure quickly leads to warped cylinder heads and blown head gaskets due to localized hot spots within the aluminum block.

The Engineering Solution

Engineered as a robust direct-replacement upgrade, this all-aluminum unit eliminates OEM failure points by replacing fragile plastic tanks with durable, 100% TIG-welded aluminum end tanks. The brazed aluminum tube-and-fin core increases surface contact area and coolant capacity, promoting superior convective heat transfer across the cooling fins. Designed with factory-matched mounting locations, port geometry, and transmission cooler provisions, it delivers drop-in reliability without cutting or custom bracket fabrication.
