Detailed Description

OSC part number 2251 is a replacement radiator engineered to match original equipment dimensions and cooling function. It features a 30 1/2-inch core height, 15 1/16-inch core width, and 1-inch core thickness, along with 1 5/16-inch inlet and outlet diameters. The radiator uses a crossflow configuration, plastic tanks, and a plated transmission oil cooler, making it a practical choice for vehicles that need dependable heat transfer and stable operating temperatures. This radiator is a direct-fit solution for 1996-2001 Chevrolet Lumina, 1998-1999 Chevrolet Monte Carlo, and 1996 Oldsmobile Cutlass Supreme applications. For buyers searching for a 1996-2001 Chevrolet Lumina radiator or a 1998-1999 Chevrolet Monte Carlo radiator, part number 2251 provides an OE-style replacement built around the original cooling system layout.

This part cross-references APDI 8012251 and Spectra Premium CU2251 for the same application.

What It Helps Address

• Overheating caused by a worn or restricted radiator core
• Coolant leaks from aging tanks, seams, or gasket surfaces
• Reduced cooling efficiency in high-mileage Chevrolet Lumina and Monte Carlo models
• Transmission heat management concerns where an integrated cooler is required
• Fitment issues from damaged or previously repaired cooling assemblies

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and cooler line spacing before installation. This radiator is built for factory-style placement, and the included fittings or hardware support a cleaner install where required by the application. Inspect hoses, clamps, and cooler lines before assembly to reduce the chance of repeat leaks. For 1996 Chevrolet Cutlass Supreme and other listed applications, confirm that the vehicle uses the same crossflow layout and transmission cooler configuration before final fitment.

Quality Assurance

OSC tests the radiator core before assembly, checks the transmission and engine oil coolers prior to installation into the tank, and tests the completed unit again after assembly. The design also incorporates engineering updates aimed at addressing original failure points and improving durability in higher-mileage vehicles. Part number 2251 is built to OE-style standards for consistent cooling performance and dependable service.
