Detailed Product Overview

This radiator is engineered to match original equipment cooling layout while adding design improvements for durability and service life. OSC uses cadmium-plated tubes inside and out to help reduce premature failure, and the radiator is assembled with a die-cut gasket to support leak resistance. The unit is built with a concentric transmission cooler and is designed for vehicles originally equipped with this cooler style. Part number 2576 is a practical OE-style replacement for Nissan 350Z cooling system service.

This part cross-references APDI 8012576 and Spectra Premium CU2576 for the same application.

Common Problems This Radiator Can Address

• Overheating caused by a worn or restricted radiator core
• Transmission fluid temperature concerns related to a failing internal cooler
• Coolant leaks from aged tanks, seams, or gasket surfaces
• Reduced cooling efficiency from damaged fins or deteriorated tubes
• Fitment issues from a radiator that no longer matches factory dimensions

Installation Notes and Tips

Verify the vehicle uses the correct downflow layout and concentric transmission cooler configuration before installation. Inspect hoses, clamps, and mounting points during replacement, and confirm the inlet and outlet connections match the original radiator. For a 2003-2006 Nissan 350Z radiator replacement, part number 2576 is built for direct-fit service with factory-style attachment points and included fittings or hardware where required by the unit.

Quality Assurance

OSC tests the radiator core before assembly, then tests the completed unit again after assembly. The transmission and engine oil coolers are also tested prior to installation into the tank, supporting consistent quality control across production.
