Detailed Description

This OSC Premium New Automotive Radiator is built to match original equipment dimensions and cooling layout. Core measurements include 26 in. height, 14 1/2 in. width, and 5/8 in. thickness, with 1 5/16 in. inlet and outlet diameters. The transmission oil cooler is included, with a 11 1/2 in. distance between fittings, while engine oil cooling is not included. Part Number 2520 is designed for direct replacement service in Chevrolet Classic, Pontiac Grand Am, and Oldsmobile Alero applications.

OSC uses engineering updates to address common failure points in higher-mileage vehicles, including improved fin density and thicker core construction where applicable. This helps maintain cooling performance while preserving OE-style packaging and appearance. This part cross-references Spectra Premium CU2520 for the same application.

What This Radiator Helps Address

• Overheating caused by a leaking or restricted radiator
• Transmission temperature concerns tied to a failing cooler circuit
• Coolant loss from cracked tanks or weakened seals
• Poor heat transfer from a clogged or damaged core
• Fitment issues from non-OE-style replacement radiators

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and transmission cooler line spacing before installation. Flush the cooling system, inspect hoses and clamps, and confirm the mounting points and fittings match the original layout. This radiator is a direct-fit style replacement for 2004-2005 Chevrolet Classic, 2002-2005 Pontiac Grand Am, and 2002-2004 Oldsmobile Alero applications.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the core before assembly, and pressure tests the completed radiator again after assembly. The unit is engineered to OE-style cooler design standards and built for consistent fit and cooling performance. Part Number 2520 is also referenced under 8012520 and 22666459.
