Detailed Description

Universal Air RA1051C is a crossflow radiator made for the listed GM platforms, including Buick Regal, Chevrolet Lumina, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix. The crossflow design routes coolant across the radiator core to support heat transfer in the vehicle’s cooling system, making this radiator a practical replacement when the original unit is worn, leaking, or no longer cooling effectively. For buyers comparing a 1990-1993 Buick Regal radiator or a 1992-1993 Chevrolet Lumina radiator, RA1051C provides a fitment-specific option. This part cross-references no listed interchange numbers in the provided data.

What It Helps Address

• Coolant leaks from a damaged or corroded radiator
• Overheating caused by restricted coolant flow
• Reduced cooling performance in stop-and-go driving
• Replacement needs for aging factory radiator assemblies
• Fitment-specific repair for select GM cooling systems

Installation Notes and Tips

Verify radiator dimensions, hose connections, and transmission or oil-cooler provisions against the removed unit before installation. This application includes 1991-1993 Oldsmobile Cutlass Supreme with engine oil cooler, so confirm that the replacement matches the vehicle’s cooling configuration. Flush the cooling system, inspect hoses and clamps, and refill with the correct coolant mixture after installation.
